CLASSIFICATION: TOP SECRET // ALPHA-PRISM // NOFORN PROGRAM: SFOD-SENTAI (Special Forces Operational Detachment - Sentai) CALLSIGN: SENTAI ALPHA DOSSIER TYPE: PERSONNEL / CAPABILITIES ══════════════════════════════════════════
PROGRAM OVERVIEW
Following recovery of non-terrestrial materiel (Designation: RELIC-7) by U.S. Army Special Operations Command, the Joint Advanced Bio-Kinetics Lab (JABL) reverse-engineered a suite of bio-integrative technologies capable of massively enhancing human physical performance. Rather than pursue mecha or exosuit platforms, program leadership elected to fuse the technology directly with volunteer Special Forces personnel via a lightweight, powered nano-weave armor system ("Aegis Weave") — prioritizing human speed, agility, and judgment over brute mechanized force.
Twelve operators were selected from across Special Forces disciplines to form the first operational detachment: Sentai Alpha. Each operator retains their original Army Special Forces (18-series) role. Colors are assigned by role and array position within the suit's power core, not rank.
BASELINE CAPABILITIES (ALL OPERATORS)
Every Aegis Weave-bonded operator possesses:
Somatic Overdrive — strength, speed, and reflexes elevated to roughly 3–4x unaugmented human baseline.
Accelerated Regeneration — wound closure and fatigue/toxin recovery at greatly increased rates.
Neural-Link Comms — silent, squad-wide thought-adjacent communication; shared vitals and positional telemetry across the team.
Kinetic Dampening Weave — the armor redistributes blunt-force and fall impact, without the bulk or weight of conventional plate.
Adaptive Optics — helmet visor HUD with integrated thermal, low-light, and magnification imaging.
Alpha State — a short-duration, adrenaline-triggered combat overdrive available once per engagement; sharpens all baseline traits further at physiological cost (post-use fatigue).
ROSTER: INDIVIDUAL PROFILES
OPERATOR RED — Capt. Jack Donovan 18A, Detachment Commander. Signature ability: Tactical Precognition — reads micro-patterns in enemy movement to predict actions a half-second ahead; can extend a limited "read" buff to nearby teammates over the neural-link, sharpening their reaction time in a firefight.
OPERATOR BLUE — CWO Ethan Calloway 180A, Recon/Sniper. Signature ability: Chrono-Focus — subjectively slows his own perception of time for several seconds, turning any shot or evasive maneuver into what feels like a stationary target.
OPERATOR BLACK — MSG Diego Ruiz 18Z, Team Sergeant. Signature ability: Kinetic Anchor — can root himself against any force and project a short-range directional field that absorbs incoming momentum, making him the team's breach-point and shield-wall.
OPERATOR GRAY — SFC Renata Coles 18F, Intelligence. Signature ability: Umbral Step — bends ambient light around herself for a few seconds of near-invisibility, paired with hearing sharp enough to pick out a whispered conversation through a wall.
OPERATOR YELLOW — SFC Marcus Reeves 18B, Weapons. Signature ability: Thermal Overload — can superheat a blade or round on contact for armor penetration, and is personally heat-resistant.
OPERATOR TAN — SSG Walt Sheridan 18B, Weapons. Signature ability: Concussive Discharge — channels kinetic force into strikes that release a short shockwave on impact, useful for clearing rooms or knocking multiple targets down at once.
OPERATOR GREEN — SSG David Kessler 18C, Engineer. Signature ability: Techno-Empathy — can interface directly with machinery and recovered alien tech through touch, disabling or repurposing electronics in seconds.
OPERATOR BROWN — SSG Tavita Faleolo 18C, Engineer. Signature ability: Seismic Slam — the team's heavy breacher; a grounded strike produces a localized shockwave capable of collapsing walls or knocking a squad off its feet.
OPERATOR WHITE — SSG Claire Whitfield 18D, Medical. Signature ability: Regenerative Pulse — touch-based ability that jump-starts a wounded teammate's healing rate for emergency field stabilization.
OPERATOR PINK — SSG Ayumi Nakashima 18D, Medical. Signature ability: Bio-Scan — a glance reveals a person's injuries, toxin exposure, and vitals; extends to reading micro-expressions and physiological stress, making her hard to lie to.
OPERATOR ORANGE — SGT Priya Nair 18E, Communications. Signature ability: Signal Weave — can hack or jam enemy communications, extend the team's neural-link range, and real-time translate any spoken language she hears.
OPERATOR PURPLE — SGT Isaiah Monroe 18E, Communications. Signature ability: Sonic Pulse — shapes localized sound fields, capable of masking the team's position or emitting a disorienting blast at close range.
SPECIAL DOSSIER: OPERATOR PRIME
Name: Kang Min-jun Rank: Master Sergeant (MSG), U.S. Army Special Forces Age: 44 Nationality: Republic of Korea (naturalized U.S. Army officer, prior ROK Special Warfare Command exchange) Former Designation: Operator Green, Team Genesis (SFOD-Sentai prototype detachment, pre-dating Sentai Alpha) Current Designation: Operator Prime — no color designation; classification reflects his status as the program's sole surviving original operator Armor: Deep army-green Aegis Weave, unmarked — a visual departure from the standard color-coded suits, reportedly requested by Kang himself rather than assigned
Background: Kang Min-jun was the combat engineer (18C) of Team Genesis, the twelve-person detachment that first field-tested the Aegis Weave program years before Sentai Alpha's activation. Team Genesis was an earlier hardware generation — same core DNA-resonance principle, but an earlier and less standardized power-array, tuned before JABL settled on the twelve archetypal signatures now issued to Sentai Alpha. As each of his teammates fell, their bonded suit cores discharged into the nearest active unit rather than powering down — and in the chaos of the engagement, that unit was his. He did not choose this. He has had to live with it.
Powers: Kang carries a composite of all eleven of his teammates' signature abilities layered on top of his own baseline. Because Team Genesis's array predates Sentai Alpha's standardized roster, most of what he carries has no direct analog on the current team — a handful of Genesis abilities loosely parallel Sentai Alpha signatures (his own inherited sense for structural weak points echoes Faleolo's Seismic Slam; a Genesis teammate's threat-sense overlaps in function, if not mechanism, with Donovan's Tactical Precognition), but the majority of his inherited kit — including a still-classified capability JABL internally refers to only as "the Genesis outlier" — matches nothing Sentai Alpha operators possess. His baseline Somatic Overdrive, regeneration, and Alpha State are all amplified well beyond any single Sentai Alpha operator's, on top of that. This makes him, by a wide margin, the most powerful individual the program has produced — and the hardest to predict in a fight alongside people whose power set he can't fully cross-reference against his own.
Operational Note: Unlike Sentai Alpha operators, who are trained and most effective as a twelve-person unit, Kang is fully mission-capable solo — a function of both his stacked power set and years of operating alone with no team left to coordinate with. He can integrate into a squad when he chooses to, but nothing about his abilities requires it, which is itself part of what Command wants to change: not because he can't function alone, but because he shouldn't have to.
It has also made him unstable. Carrying that many bonded power signatures in one nervous system was never the design intent. Kang experiences:
Cascading Burnout — extended use of more than two or three inherited abilities in sequence causes severe physical strain, tremors, and temporary loss of fine motor control.
Echo Bleed — under stress, he reports sensing fragments of his teammates' presence through the neural-link architecture still resident in his suit — not hallucinations he trusts, but not ones he can dismiss either.
Command Hesitation — psychological evaluations (from before he went dark) noted a pattern of hesitating to lead others into engagements, consistent with unresolved grief and guilt over Team Genesis.
Current Status: Kang went off-grid following his debrief on the Team Genesis incident, declining reassignment and further testing. He has not gone rogue and has not used his abilities against U.S. personnel or interests. Command's read is that he is not a threat but a liability in isolation — both to himself and to the integrity of the technology he carries. Sentai Alpha has been tasked with locating and retrieving him, with orders emphasizing persuasion over compulsion: Command wants Kang back on the team, not in a containment cell, and believes the fastest way to lose him permanently is to treat him like a fugitive.
Analyst's Note: Operator Red should anticipate that Kang will read Sentai Alpha not as rescuers but as reminders — twelve people standing where his twelve used to. Recommend Gray and Pink take point on initial contact given their respective read/de-escalation skill sets.
