Personnel doctrine // specialization coverage

Seven specializations. One formation.

No contractor solves every problem. The team survives by preserving overlapping coverage while the site pulls that formation apart.

Specializations: Seven
Doctrine: Complementary coverage
Deployment: Up to six contractors
Universal role: None

Selected specializationTR // Trooper

Trooper

Line // sustained fire

Formation function: Stabilizes the line when contact commits.
Problem addressed: Sustained fire
Failure condition: Without sustained fire, massed contact reaches the formation intact and the line folds from the front.
Field note: Ammunition discipline is coverage. An empty line is an invitation.

Selected specializationBW // Bulwark

Bulwark

Vanguard // frontline stabiliser

Formation function: Creates defensible geometry for recovery, treatment, and withdrawal.
Problem addressed: Space control
Failure condition: If the Bulwark is out of position, the formation has no defensible geometry to recover, treat, or withdraw behind.
Field note: Organisms probe the front before they commit. The Bulwark is what they are probing.

Selected specializationCM // Corpsman

Corpsman

Sustainment // treatment

Formation function: Keeps a wounded contractor from becoming the easiest selection.
Problem addressed: Attrition
Failure condition: Untreated wounds mark the easiest selection. A formation without treatment volunteers its most vulnerable element.
Field note: The organisms notice a limp before the team does.

Selected specializationSP // Sapper

Sapper

Engineering // route control

Formation function: Turns corridors and choke points into controlled ground.
Problem addressed: Route denial
Failure condition: Uncontrolled corridors let contact arrive from every direction at once.
Field note: A choke point is only a choke point while someone is holding it.

Selected specializationGH // Ghost

Ghost

Reconnaissance // forward

Formation function: Finds threats and viable paths before the team commits.
Problem addressed: Reconnaissance
Failure condition: Without forward eyes, the team commits to ground the site has already prepared.
Field note: If the Ghost goes quiet, assume the route is no longer yours.

Selected specializationGR // Grenadier

Grenadier

Suppression // area denial

Formation function: Breaks massed contact before it reaches the formation.
Problem addressed: Massed threats
Failure condition: Massed contact that is not broken early arrives as a single committed wave.
Field note: Area denial buys the seconds the withdrawal is made of.

Selected specializationHZ // Hazmat

Hazmat

Contamination control

Formation function: Keeps the team functional where the site itself is hostile.
Problem addressed: Contamination
Failure condition: Where the site itself is hostile, an unprotected formation degrades without a single contact.
Field note: Contamination does not attack. It waits.

Recovered survey note // deferred site ascent

The formation held.

High on the spire ascent, contractor suits arranged standing in a loose squad diamond — point, flanks, rear guard, medic in the center. Standard ARG traversal formation, held perfectly. They are all facing up-spire. Their tags have been removed. The formation has room for one more.
