1. ANTI-BIOTERRORISM ORGANIZATION "DSO" EQUIPMENT DEVELOPMENT PROJECT
The Necessity Of Anti-Bioterror Equipment
The operations of DSO agents are mainly investigation and espionage.
They're supplied with firearms and high-performance handguns with portability as the main focus, but firearms developed for military and law enforcement organizations weren't developed with special situations like bioterror and biological weapons in mind.
It could be said it was a natural flow to provide equipment, developed daily "for proprietary use", to agents facing special situations and missions.
Reviving The Sentinel Project
A large anti-bioterror force named the "FBC" (Federal Bioterrorism Commission) once existed in the United States of America. The FBC was a military unit tasked with suppressing bioterrorism as an organization with different properties than the DSO, but it conducted proprietary development of equipment using its abundant financial power, equivalent to the military budget of a small country.
The codename "Sentinel" was given to this equipment development project specializing in anti-bioterror.
The Sentinel Project also vanished due to the FBC's dissolution.
However, the DSO had its eyes on a vast quantity of data, such as analysis of the various equipment and manufactured trial products devised in this project, as well as the unique circumstances brought by bioterror, and they revived the Sentinel Project.
Leon S. Kennedy & Sentinel Project
Participating as a supervisor to the Sentinel Project revived by the DSO was Leon S. Kennedy, a representative agent of the DSO who has experienced scenes of bioterror time and time again.
This was because Leon's abundant experience in surviving bioterror was useful for developing equipment, such as Raccoon City in 1998, Operation Javier in 2002, and the kidnapping of the President's daughter in 2004.
He once used the powerful "Desert Eagle" magnum handgun and became well versed in small arms through much combat experience, gradually becoming an expert.
● What Is The DSO?
An American organization formed to defend the nation from many threats, including "bioterrorism."
DSO is an abbreviation of "Division of Security Operations."
Agents with the flexibility and readiness for responding to special circumstances were selected from various organizations and operate within an agent organization under the President's direct command.
In many cases, their operations are centered on espionage and investigations conducted "solo" or with "a small number of people."
● Material Left By FBC (Excerpt)
There's an interesting passage in the documentation of the FBC's Sentinel Project.
"...OVERALL: As a result of studying and analyzing every weapon in the world; we, the FBC Small Arms Resarch Group, have decided on the gun to become the handgun's base from the Beretta corporation's "M92F", the IMI corporation's "Desert Eagle" and the SIG corporation's "P226R" which squeezed three marks (omitted) the SIG corporation's P226R led to the desirable result in the end..."
The interesting thing is that, among handguns, it means the FBC Small Arms Research Group narrowed down the M92F, Desert Eagle and P226R.
"The usefulness of the Samurai Edge in combat" is present in another file, proving that the "Samurai Edge" used by S.T.A.R.S. was thoroughly analyzed.
※1: SAMURAI EDGE SYSTEM
The Samurai Edge which appears in the games is a M92F-based handgun that was custom-made by the gunsmith Joe Kendo for the S.T.A.R.S. officers.
In addition to the standard model provided to S.T.A.R.S. officers, Chris, Jill, Barry and Wesker each personally asked Joe Kendo for further customs.

2. SITUATIONAL ANALYSIS, THREE KEYWORDS, AND SELECTING THE BASE GUN
What Are Unique Situations Caused By Bioterrorism?
Unlike developing normal equipment, developing anti-bioterror equipment must account for critical situations such as "confronting creatures mutated by virus-infected organisms and intentionally-made B.O.W. (Bio Organic Weapons)", and "environments where bioterrorism has paralyzed lifelines and logistical support."
Some creatures and B.O.W.'s possess tremendous strength and athletic capabilities, covered with hard skin that can block bullets, or attack with bodily fluids that harm the human body and materials, and all are extremely aggressive toward humans.
Additionally, combined with the fear of bioterror in areas overawed by chaos, destruction by creatures and B.O.W.'s will also extend the damage to lifeline and traffic functions. Even when acting as members of an anti-bioterror organization, logistical support such as supplying ammunition doesn't always go smoothly.
Planned routes to a destination can be blocked, forcing you to search dark and narrow roads devoid of light. Even in situations like that, creatures and B.O.W.'s attack mercilessly.
On the basis of such situations, Leon, who became supervisor of the Sentinel Project, presented to the DSO "three keywords" to guide the development of anti-bioterror equipment.
The Keys Are "Versatility, Certainty, Stability"
When developing a dedicated anti-bioterror handgun for DSO agents, a base gun was selected first. The keywords for that purpose are the three keywords presented by Leon: "versatility", "certainty", and "stability."
● VERSATILITY
Generally means "wide-ranging usage", but here refers to "ease of replenishing ammo during mission."
Powerful "magnum ammo" is effective against creatures and B.O.W.'s possessing tough outer skin and high durability. This ammo's very difficult to secure in Japan.
As a result, focus was given to handguns that use "9mm Parabellum bullets", which has a high penetration rate and is relatively easy to replenish ammo anywhere. 9mm Parabellum bullets can be found not only in urban gun shops, but also in ordinary households with handguns for self-defense.
● CERTAINTY
"Ensure it works in any situation" is the most important point in developing combat equipment. There should never be an accident on-scene. Malfunctions such as jamming lead to life-threatening conditions.
Developing handguns usually takes into account changes in weather and the environment.
Dust and sand getting inside, damage and deformation of parts due to extreme high and low temperatures, rust due to rain and seawater, etc. In order to prevent malfunctions caused by these, various ingenuities have been applied to the gun's structure, materials and surface finishing.
However, when taking bioterror into account, this isn't enough.
As Leon himself has experienced, creatures and B.O.W.'s may eject bodily fluids similar to strong acids. Therefore special measures need to be considered particularly for the materials and surface finishing.
● STABILITY
Handguns are much smaller and lighter than assault rifles or submachine guns and enable swift movement while standing, often used to confront targets at short distances.
In close combat it's important to "hit the target quickly and accurately." There are some creatures and B.O.W.'s that attack by closing the distance from a few meters away. In the field of bioterror, not taking a shot is simply exposing yourself.
Manipulating a gun's trigger and lever without stress leads to "swiftness." In addition, Leon argues that ease of aiming and accuracy of hitting, and especially the sense of stability when holding a gun, are points of "accuracy" and that a grip which fits in the hand is indispensable.
A gun that reflects the shooter's ideals is the agent's partner. Leon also states that such a great sense of trust in a gun will bring stability to one's mind in situations where they're mentally driven into extreme conditions.
Selecting The "P226E2"
As the custom base for the handgun dedicated to anti-bioterrorism, from the three keywords of "versatility", "certainty" and "stability", Leon chose the handgun "P226E2" from SIG, a well-established firearms manufacturer prided by the industrial powerhouse Switzerland.
The "P226", elaborate and Swiss-made, once competed with the M92F for final selection by the US military. The M92F has evolved into the S.T.A.R.S. "Samurai Edge." How will the P226E2 evolve in the hands of the DSO?
Through this, the "Sentinel Project" finally entered the full-scale development phase.

3. WHAT CUSTOMS SPECIALIZE IN BIOTERRORISM?
US Navy Special Operations Force SEALS & SIG P226
The P226E2 selected as the base for the DSO's dedicated anti-bioterrorism handgun is an improved model of the P226 adopted by the US Navy Special Operations Force "SEALs."
SEALs have many "grand" missions such as infiltration, reconnaissance and surveillance and are particularly adept at underwater ops.
The "sentinel" in the Sentinel Project advanced by the DSO is one of the vital roles of "sentry." DSO agents head into the field first to advantageously combat bioterrorism, DSO agents will be first on the scene and, acting as the organization's "eyes", their espionage and investigation lead to the resolution of incidents.
The P226 was selected as a buddy by the SEALs who, like the DSO, take on the role of sentries. One could say the improved model P226E2 is an ideal model as a base for handguns dedicated to anti-bioterrorism.
● What Are SEALs?
US Navy Special Operations Force "Navy SEALs." "SEALs" is an acronym of Sea, Air and Land, but as the name suggests, they're an elite unit of small number that conduct missions on the sea, in the air and on land.
Their missions are complex and diverse, such as coastal patrols, airborne infiltration and enemy area recon, so their equipment is often developed independently or made-to-order by manufacturers.
The P226 used by the SEALs was also changed to rust-resistant specifications per their request.
"SIG P226E2" Basic Performance & Improvements
The P226E2 balances "safety" to prevent accidental discharge while carrying, and "quick response" able to react quickly to situations without operating the safety. Also, "E2" stands for "Enhanced Ergonomics", and as the words indicate, it adopts a design that incorporates "ergonomics" and has favorable operability.
Of course, the model is exceptional in terms of accuracy and durability, but if it's to be provided to DSO agents, further improvements are required with "anti-bioterrorism" in mind.
The DSO will solve the following issues based on the keywords of "versatility, certainty and stability" and perfect the P226E2 as a handgun dedicated to anti-bioterrorism.
P226 E2
Caliber: 9 mm
Overall Length: 112 mm
Weight: 964 g
Capacity: 15 Rounds (+1 in Chamber)
Increase Magazine Load
If the 9mm Parabellum bullet's inferior in power compared to the Magnum bullet, it'll be compensated by the number of bullets. The magazine should be loaded with as much ammo as possible.
[Main Improvements] Magazine
Improve Corrosion Resistance of Exterior Parts
Considering the effects of bodily fluids generated by creatures and B.O.W.'s, it's essential to review the materials and finish processing, especially for moving parts, in order to prevent the parts from deteriorating and malfunctioning.
[Main Improvements] Slide, hammer, trigger, magazine catch, slide stop, decocking lever, take-down lever, etc.
Improve Speed of Operation
Endeavoring to improve the operability of the various levers to prevent any operational mishaps will lead to quicker shooting.
The setting should be based on the notion of single action (※1) fire.
[Main Improvements] Hammer, trigger, magazine catch, slide syop, etc.
Improve Accuracy
There's a need to further pursue stability when holding the gun, and ease of aiming in the dark.
Especially when gripping, think not only of the ease of gripping but also the difficulty of sliding. Additionally since it's effective to shoot multiple creatures and B.O.W.'s in weak points, we need to further reduce recoil so it can be used easily during continuous firing.
[Main Improvements] Grip, muzzle (barrel), front/rear sight, etc.
※1 "Single action" refers to a handgun's firing mechanism, meaning that the hammer moves (action) when pulling the trigger. If the hammer is raised prior to pulling the trigger, it will fire in single action.

6. CUSTOM ANALYSIS (1) ADAPTABILITY TO SPECIAL ENVIRONMENTS
Birth Of The Sentinel Nine
Within the DSO's Sentinel Project, various custom-made handguns dedicated to anti-bioterrorism were developed, based on the P226E2.
In the final stage, two types of custom candidates were narrowed down, and after passing through a trial (*1), the "Sentinel Nine" won the DSO's adoption.
The model name Sentinel Nine was originally a codename attached during development to represent the "9th prototype", but the ammunition it uses is sometimes the 9mm Parabellum bullet, so it would simply be used as the name after being formally adopted by the DSO.
The Sentinel Nine was reborn from the P226E2 at the hands of the DSO as a handgun dedicated to anti-bioterrorism.
First let's look at the final specifications from "adaptability to special environments."
※1. When a new firearm is adopted by the military or police an employment test is conducted, referred to as a "trial." Within the trial, tens of thousands of shots are fired to test accuracy and durability, and rigorous tests against drops, impacts, high and low temperatures etc. are performed, and improvements and tests are repeated until it attains a standard of adoption. If it's a DSO trial with a focus on anti-bioterrorism, the contents will be even more severe.
The Field Of Darkness Agents Face
The most inevitable situation in the field of bioterrorism is "darkness." It's always night out once a day and even during the day there are many dark indoors. Situations where the power supply is cut and there's no lighting are also conceivable.
If the enemy is a human like the agents, the darkness is a five minute situation. However, some creatures and B.O.W.'s can detect prey via sound or smell. Fighting in the dark can be an overwhelming disadvantage for an agent.
The Sentinel Nine assumes the following measures for use in the dark.
● Front Sight & Rear Sight
The Sentinel Nine's sights are focused on acquiring a target. The dot parts of the sights are filled with a "phosphorescent agent" that stores and emits light, and are visible even in the dark.
The dots on the front sight are square and the dots on the rear are shaped a very rare triangular, but this is designed to ensure you can reliably see and act quickly against unexpected attacks.
The sights have a "stealth shape" where light reflection is less likely to affect sighting, and the sights have been made smaller and less likely to catch on clothing.
● Body Color
Taking operations in the dark into consideration, it's usually desirable to unify the color of equipment with black that can't be noticed.
However, it could fall to bad footing. It can be blown away by a creature's strong blow. In the unlikely event you lose that gun, it'll be difficult to find a black-colored gun in the dark.
The Sentinel Nine dares to make some parts, such as the slide, silver in order to "make it easier to see the gun even in dim darkness."
● Mount Rail
The mount rail is a specification of the base P226E2 and isn't a custom of the Sentinel Nine, but it's an indispensable specification for operations in the dark.
The grooves at the front of the trigger on the gun's bottom are called the mount rail and most guns use a 20mm wide (Picatinny standard) mount rail. This part can be equipped with flashlights and laser pointers of the same standard.
With the gun grasped in both hands, you can turn on and illuminate the light etc, so mount rail models are increasingly being adopted especially in units that take part in much indoor and night combat.
Thorough Measures Against "Corrosion"
The Sentinel Nine has been subjected to a phosphate film treatment (parkerizing). This is a major surface treatment to prevent rust that can cause malfunctions, which is also utilized on the P226 of the US Navy Special Operations Force SEALs, who are highly active in water.
However there's something else to watch out for in the bioterror field besides rust caused by rain or moisture. Bodily fluids from creatures or B.O.W.'s.
These bodily fluids not only harm the human body but may also corrode materials and deterioate them. For that reason, the Sentinel Nine adds a special surface treatment, unaffected by bodily fluids, onto the phosphate film treatment.
From the precaution that these treatments are applied not only to the external parts but also the internals, it's possible to grasp the magnitude of the effect of "corrosion."
The slide which is key to its operation is made through cutting using a special alloy material resistant to rust, special chemicals, etc, taking its strength and durability into account.
On the slide's left side is the model name (SENTINEL NINE), caliber (9mmX19), organization name (Division of Security Operations), and engraved with the DSO's motto "PEACE THROUGH FIGHTING." From these words engraved on the slide you can feel the strong philosophy of DSO agents.

7. CUSTOM ANALYSIS (2) MUZZLE CONTROL AND OPERABILITY
Challenging Bioterrorism With The 9mm Parabellum
The 9mm Parabellum bullet used in the Sentinel Nine is one of the "most readily available ammunition" popular around the world.
Although within a single shot it's inferior in power to the Magnum bullets used by the Desert Eagle, the 9mm Parabellum bullet has the advantage of supplementation. That is, "recoil is minor" and because the size (diameter) of the bullet is small, "the magazine number is large." If recoil's minor, it's easy to control the muzzle direction even if firing in quick succession, and you can aim for a hit after the second shot.
If you can shoot multiple bullets at the weak point of a creature or B.O.W., even the 9mm Parabellum can expect significant damage. If you have a DSO agent's skills and the Sentinel Nine's performance, you can expect a bigger effect than a Magnum bullet.
▲ 9mm Parabellum Bullet
The name "Parabellum" is derived from the Latin phrase "If you want peace, prepare for war" and it's connected to the DSO motto "Peace Through Fighting."

A gun's bullets don't hit as intended if aim's inaccurate. In the action of "pulling the trigger to fire the bullet", there are many elements that cause a decrease in hit rate such as shaking when using the trigger, significant recoil when firing, and muzzle flash.
In order to strike several bullets at the weak points of creatures and B.O.W.'s, the Sentinel Nine compensates for the aspects that cannot be covered by the shooter's skills alone.
● Flash Hider & Long Barrel
The Sentinel Nine's barrel is about 10mm longer than that of the P226E2. By extending the barrel length, the trajectory of the bullets fired is more stable, and the tip is threaded to allow silencers to be easily installed. (※1)
A "flash hider" for suppressing muzzle flash is standard on this thread. The front face-like spike shape is designed to limit the spread of the muzzle flash.
In addition, the side port (hole) is for releasing the gas to be blown and has the effect of suppressing the muzzle of the blown-out gas that pops up upon reacting.
● Hybrid Grip
Although the power of the 9mm Parabellum bullet is inferior to the Magnum bullet, the fired bullets have sufficient offensive power and recoil when firing them is small enough to be easily restrained by human strength.
The Sentinel Nine seeks ease of grip and fit to hold the recoiling gun firmly with both hands. As a result of thorough research on the differences in roundness and angle, we arrived at this "hybrid grip."
A grip loaded with much pickiness such as a thumb rest intended for right-hand use, a DSO medallion on just one side, and a rubber finish making sliding harder, providing perfect holdability.
● B Trigger
The Sentinel Nine trigger is called a "B Trigger" because it resembles the letter "B." Handgun trigger shapes vary but the B Trigger's a particularly unique design.
The Sentinel Nine's for single-action use that can respond immediately even in emergencies, and the trigger in single action is at position (B). The reason why the front of the trigger (the part touching the finger) is flat is to transmit the force of the finger to the trigger without waste when pulling the trigger from position (B).
The more force applied to the finger pulling the trigger, the easier the muzzle will shake. Smooth triggering is an important factor in precision shooting.
In addition, the B Trigger has two cut-out holes.
When the trigger returns to position (B) after firing, the trigger's lightened and returns faster. It's a slight difference that goes unnoticed initially, but the nerves in the fingertips are sensitive to differences in how quickly the trigger returns. Especially when pulling the trigger many times and firing rapidly (sequential firing without pause), if the trigger feels uncomfortable it'll cause the shooter significant stress.
Increasing Bullet Number & Smooth Magazine Changing
When using 9mm Parabellum bullets, the DSO enables rapid-fire attacks against creatures and B.OW.'s which means that more bullets are spent.
If the magazine placed in the gun is empty, you'll be unprotected while changing the magazine. However, if the number of bullets in the magazine's increased as much as possible, the number of magazine changes will be reduced, and if the magazine can be replaced quickly and smoothly, the gap will be reduced.
● Long Magazine
The long magazine used in the Sentinel Nine holds 20 rounds. This is five more than the usual magazine for the P226E2, and the magazine's also longer.
This magazine, also referred to as a "SEALs magazine", is heavy because the bottom's reinforced with an iron plate. If you press the magazine catch it'll easily fall by its own weight and you can efficiently change the magazine.
● Magazine Catch
A large square-type magazine catch is used to ensure the magazine can be replaced in any situation. Although it's large and easy to push, it's designed to not jam when handling the Sentinel Nine.
The DSO resurrected the Sentinel Project previously advanced by the FBC and finally created the Sentinel Nine handgun, dedicated to anti-bioterrorism.
At the DSO only a few were initially manufactured and combat data was collected by Leon, the Sentinel Project's supervisor.
However in 2013, before Leon received the Sentinel Nine, a large-scale bioterror incident occurred at Tall Oaks in the United States.
Although it was finally in Leon's hands after the incident was resolved, combat data collection has yet to be completed. Full-fledged production of the Sentinel Nine and the official issuing date to DSO agents remain undecided.
● Gun Case
The gun case containing the Sentinel Nine is also supplied by the DSO. Made of high-strength polymer with excellent shock absorption, it's a tough case that doesn't affect the gun stored inside even if dropped from the sky or run over by a tank.
Displayed on top of the case are the DSO emblem, model name, serial number, etc., which prove the product is supplied by the DSO.
Challenging Bioterrorism With The 9mm Parabellum
The 9mm Parabellum bullet used in the Sentinel Nine is one of the "most readily available ammunition" popular around the world.
Although within a single shot it's inferior in power to the Magnum bullets used by the Desert Eagle, the 9mm Parabellum bullet has the advantage of supplementation. That is, "recoil is minor" and because the size (diameter) of the bullet is small, "the magazine number is large." If recoil's minor, it's easy to control the muzzle direction even if firing in quick succession, and you can aim for a hit after the second shot.
If you can shoot multiple bullets at the weak point of a creature or B.O.W., even the 9mm Parabellum can expect significant damage. If you have a DSO agent's skills and the Sentinel Nine's performance, you can expect a bigger effect than a Magnum bullet.

"SENTINEL NINE" DEVELOPMENT KICKS OFF
CAPCOM Managing Executive Officer Takeuchi-san is quite a gunmaniac and we meet every time at the Osaka Shot Show (a military event). Whenever we met up, our favorite phrase is "we want to do some new collaboration project."
It was when we met in 2011 that we were able to develop the Sentinel Nine. That year was exciting with BIOHAZARD's 15th anniversary and we could expect further excitement in 2012 with the release of the movie "biohazard DAMNATION", so we said "let's get started with the collaboration model project" in earnest.
Of course at that time, the concept of the Sentinel Nine hadn't been made yet. However we resold the Chris and Barry models of the Samurai Edge in 2011 and were about to begin a new development with the Samurai Edge.
The main character of "BIOHAZARD 6" was Leon, so we decided on the "Leon Model" early.
We also wanted to use the familiar Desert Eagle as the base. If you've purchased the "Desert Eagle 50AE 10-inch Barrel Leon Custom", you'll find the "Desert Eagle 10-inch Full Barrel Custom" in the manual as "Leon's own rough sketch." We thought this would be a good product.
・Desert Eagle 10-inch Full Barrel Custom
Leon's rough sketch that was published in the manual of the Leon Custom released as a limited edition in 2008.
But Leon's Desert Eagle has been released in three types, and within Tokyo Marui there were voices asking "Is the Desert Eagle really better?", so we considered other models as well.
Then we received a request from the CAPCOM producers to "make it a model different from the Desert Eagle", so we decided on the direction of "a new model, organized like the Samurai Edge, different from the Desert Eagle." (※1)
HANDGUNS THAT AROSE AS CANDIDATES FOR THE CUSTOM BASE
The direction of "a new model, organized like the Samurai Edge, different from the Desert Eagle", had been decided, and next was squeezing the handgun that would be the base.
Tokyo Mari is constantly considering custom models for various handguns. Firstly we chose two proposals based on the "Glock" and "SIG P226" and asked for CAPCOM's opinion.
There are actually not many handguns that can be used as custom bases.
In addition to the Glock and SIG P226, there's the M92F, Government, Desert Eagle, high capacity models (our Hi-CAPA 5.1 and such), which are popular around the world and have an abundance of custom parts.
However, the "M92F" is the base gun for the Samurai Edge, and the "Desert Eagle" was excluded from these candidates.
We've already developed various variations of the "Government" and "Hi-CAPA" so there'd be little impact as precious collaborative models.
There are other models such as the "XDM-40", "PX4" or "FN5-7", but these are relatively new models and questions arose relating to their popularity compared to major models like the M92F and Government.
CAPCOM seems to have wanted a "SIG P226 Custom" and we received the OK because we based it on the P226E2, which is an improved model of the P226.
The "SIG P226" gun is an exceptionally "perfect tool" and is an ideal model for chosen DSO agents. Taking advantage of its strengths, we will apply a biohazard-like custom that takes "anti-bioterror" into account.
● SIG SAUER P226R
A high-performance automatic pistol used by military and police organizations in various countries, including the US Navy Special Operations Force SEALs. The P226E2 is an improved model of the P226R.
