Specialized Entity Neutralization Tactical Ammunition

The Specialized Entity Neutralization Tactical Ammunition (SENTA) is a highly specialized version of the 10mm Auto round, designed to neutralize supernatural entities. While the 10mm Auto is renowned for its balance between penetration and stopping power and is favored in specialized roles within the U.S. Department of Justice, the SENTA Round takes it a step further by incorporating a unique and classified blend of metals. This specialized composition enhances its capabilities against supernatural threats like vampires and werewolves. Ideal firearms for deploying the SENTA Round include the Glock 20, known for its high magazine capacity and reliability; the Colt Delta Elite, a 1911-style pistol; and the Smith & Wesson 610 revolver, which offers the flexibility of using moon clips for faster reloading.

Capabilities

The SENTA Rounds are specialized versions of the 10mm Auto round, designed to neutralize a variety of supernatural entities. The standard 10mm Auto round, which serves as the foundation for the SENTA Rounds, has a muzzle velocity ranging from 1,200 to 1,600 feet per second (fps) and a muzzle energy of 550 to 750 foot-pounds (ft-lbs). These ballistics contribute to the round's penetrating power, allowing it to pass through various barriers, including clothing and some soft body armor. The effective range of the SENTA Rounds is up to 50 yards, similar to the 10mm Auto, but skilled operators can achieve accurate shots at even greater distances.

Specialized Composition and Target Entities

The SENTA Rounds are specialized ammunition designed for use against various supernatural entities and come in three distinct types: SENTA-A, SENTA-B, and a specialized sub-type, SENTA-C. SENTA-A rounds, officially designated as "Primary Entity Rounds," are specifically engineered for use against vampires and lycanthropes (werewolves). These rounds feature a silver core encased in an Ethylene-vinyl acetate (EVA) shell. SENTA-B rounds, known as "Exotic Entity Rounds," are primarily intended for use against Fae creatures and some types of demons. These rounds have an iron core and are also encased in an EVA shell. SENTA-C rounds were developed at Ad Undas in Los Angeles in response to a demon threat that rendered SENTA-B rounds ineffective. These specialized rounds are designed to penetrate even thick demonic hide and are particularly useful against entities with significant regenerative capabilities.

Stopping Power and Cumulative Effect

While the SENTA Rounds possess significant stopping power against mortal targets, their effectiveness against powerful supernatural entities may be limited with a single shot. The specialized composition of the rounds, which includes either a silver or iron core depending on the type, allows for incremental damage to most supernatural creatures when used successively. It is crucial to understand that the effectiveness of the SENTA Rounds will vary depending on the specific vulnerabilities and resistances of the supernatural entity in question.

Composition

The SENTA Rounds come in two basic types: SENTA-A and SENTA-B, with a specialized sub-type known as SENTA-C based on the SENTA-B design. SENTA-A rounds are identified by a bright blue tip, and their corresponding magazines are labeled with a blue mark. Conversely, SENTA-B rounds feature a bright purple tip, and their magazines are similarly marked with a purple label. SENTA-C rounds are identified by a yellow tip and magazines are also marked with a yellow label. SENTA-A and B rounds utilize a thin Ethylene-vinyl acetate (EVA) shell that acts similarly to a sabot as the round is fired. SENTA-C rounds use a polycarbonate shell.

SENTA-A: Primary Entity Rounds

SENTA-A rounds, officially designated as "Primary Entity Rounds," consist of an EVA shell with a silver core. The round is engineered to penetrate the target while leaving its EVA shell behind, thereby exposing the target to the silver core. Given that most supernatural entities susceptible to silver are physically more resilient than humans, the silver core is particularly effective.

SENTA-B and SENTA-C: Exotic Entity Rounds

SENTA-B rounds are designated as "Exotic Entity Rounds" and are tailored for less commonly encountered entities. These rounds feature an iron core with lead channels equidistant along the core's exterior, all of which is covered by the EVA coating. The channels are designed to increase the likelihood of the core breaking apart upon hitting bone, thereby enhancing the round's cumulative harmful effects. However, some exotic entities are resistant to this design, leading to the development of SENTA-C rounds. These rounds replace the EVA coating with polycarbonate and do not feature the lead channels. SENTA-C rounds are intended for use against entities with significant regenerative or penetration-resistant capabilities. The polycarbonate coating remains intact until impact, allowing for maximum penetration.

Security Protocols and Classification

The SENTA Rounds remain a highly classified ammunition to this day. Their distribution and use are strictly controlled by the Pentagon and DARPA. Only personnel with specific security clearances and command authorization are allowed access to this ammunition. This level of classification ensures that the round is used only in the most critical of applications, maintaining its exclusivity and strategic importance. The existence of supernatural entities is a closely guarded secret, and any widespread knowledge of the SENTA Rounds would compromise that secret and jeopardize the uneasy truce that keeps vampires and humans from the potential of open conflict.

Design History

The Specialized Entity Neutralization Tactical Ammunition (SENTA) Rounds have a complex history that traces its roots back to 1983 with the development of the 10mm Auto round by Jeff Cooper. However, the initial designs for SENTA moved at a sluggish pace and yielded poor results until the late 1990s. A significant turning point came with the advent of the Russian 9×21mm Gyurza ammunition, which utilized a sleeve almost akin to a sabot. This Russian innovation was instrumental in the development of the SENTA round, as it required specialized materials to achieve its unique capabilities.

The Pentagon initially took an interest in the 10mm Auto round for its potential military applications against supernatural entities. However, it wasn't until 1995 that the development of SENTA Rounds truly began, inspired by the Russian 9×21mm Gyurza ammunition. Prototypes were created in 1997, and rigorous tests were conducted in collaboration with the Defense Advanced Research Projects Agency (DARPA) to ensure the round met stringent performance and reliability criteria. By 2005, the SENTA Rounds had gained popularity among specialized military units.

Parallel to its military use, the SENTA Rounds also saw adoption by U.S. Law Enforcement agencies by 2005. The Federal Government strictly controlled the distribution of this highly classified ammunition to various law enforcement departments. Access to the SENTA Rounds required specific security clearances and was authorized only through command channels within both the Pentagon and DARPA.
