Overwatch
Overwatch is an action that ends a unit's turn, and has them hunker down and fire at any enemy unit that moves through their Target Area. The Overwatching unit can fire a number of times equal to the amount of Action Points invested. Overwatch Shots have a 50% chance to immediately Stop a target's movement. If an Operator holding an Overwatch takes damage, they will exit Overwatch and all remaining shots are lost.
