Chance to ignore melee damage and instantly respond with a melee strike.
Execute
Mutons can perform a finishing move on an adjacent stunned enemy.
Suppression
Fire a barrage that pins down a target, grants reaction fire against it if it moves, restricts the use of many abilities, and imposes a -30 penalty to the target's aim. If multiple targets suppress a target, the aim penalty will stack. Suppression is canceled if the suppressing unit is damaged. Costs two ammo.
