1965, Vietnam.

You arrive at the 173rd Airborne Brigade not as a frontline fighter, but as the administrative officer responsible for keeping a platoon alive on paper.

Your decisions determine everything:
– who deploys,
– who rests,
– who gets promoted,
– who goes home,
– and who will remain forever inside a personnel file.

12 Months: Vietnam is a minimalist yet emotionally heavy, paper-based military simulation inspired by historical statistics, period-accurate organization, and real wartime casualty patterns.

Your task is simple only on paper — survive your Tour of Duty while keeping your unit combat-ready.

In reality… nothing about it is simple.

► Tour of Duty Simulation (12-Month Cycle)

Every soldier serves a 12-month tour, with optional extensions up to 3 tours — if morale allows it.

Soldiers constantly:
– arrive
– rotate out
– get wounded
– recover
– die
– change roles
– or extend their service

You must maintain a deployable platoon at all costs.

► Morale System That Truly Matters

Every decision affects morale:

– medals
– rest
– casualties
– promotions
– injuries
– deployments

Low morale collapses the entire unit.
High morale boosts survival — but nobody is bulletproof.

► Injuries and Consequences

– Three wounds = automatic discharge
– Severe wounds = permanent removal from duty
– Every death lowers morale and adds pressure on you

► Promotions & Qualifications

Wartime cares nothing for protocol.
If a leader is needed, even a fresh replacement may be promoted instantly.
The machine must keep turning.

► Paper-Based Presentation

The entire game takes place inside the administrative reality of the platoon:

– dossiers
– reports
– assignment boards
– personnel files
– wounded and casualty logs

No combat.
No cinematics.
Just the quiet horror of paperwork in war.

► A System Built on Chain Reactions

Every choice ripples outward:

→ bad choises

→ more injuries

→ morale collapse

→ an undeployable unit

→ you are relieved from duty

Every campaign is different:

– different timings

– different casualties

– different outcomes

Infinite replayability — with a finite number of men.

► You Can Send Them Out — But You Can’t Bring Them Back

The game offers:
no reload
no undo
no alternate saves

Every choice is final.

This Is Not…

 Not an action game
 Not a shooter
 Not a power fantasy

This is a responsibility–morale–decision simulator, depicting the most invisible yet most brutal side of war: the administrative burden of keeping a unit alive.

The game does not depict:
– civilian casualties
– graphic violence
– real historical tragedies
– war crimes

Everything occurs within fictionalized military structures.
