Suppression reduces Aim of the affected unit by 50 and triggers an Overwatch shot if the unit moves. The suppression can be broken if the unit dies and sometimes when it receives damage. Uses 2 ammunition.


Fire a barrage that pins down a target, granting reaction fire against it if it moves, and imposing a -50 penalty to the target's aim.

–In-game description

  • Suppression costs 2 ammo points to use, but has no cooldown.
  • Suppression will be canceled if the suppressing unit is damaged.
  • If multiple units suppress a target, the aim penalty will stack.

1. Verify if Suppression is guaranteed to be canceled when the suppressing unit takes damage.
2. Test and determine what other means can remove the Suppression, and which do not affect it.
3. Test if multiple Suppressions can stack (as stated in-game) and, consequentially, nullify the enemy's Aim..
