XCOM 2/ADVENT Trooper

"These guys make up the bulk of the ADVENT forces we've dealt with. They're disciplined and well-equipped but their obedience makes them predictable" ~Central Officer Bradford.



ADVENT troopers are the earliest and most common enemy type encountered in XCOM 2. They possess a relatively straightforward set of abilities consisting mostly of offensive actions.

Stats
Assume unlisted values are 0 or N/A. Unless otherwise specified, all damage ranges are uniformly distributed - each outcome is equally likely.

The grenade has a 67% chance to deal 3 damage and a 33% chance to deal 4 damage

Behavior
Enemy behavior is processed one action at a time. Figure out what they will do in the first action, and then figure out what they will do in the second action from their new position with their last action point. Actions are bolded. Actions higher on the list are always attempted first if the conditions are met. The conditions are italicized.

The ADVENT Trooper may take on one of many AI jobs. These generally affect their behavior in extremely minor ways, such as causing them to attack civilians in retaliations, attack the device in protect device missions, or randomly enter overwatch when they could have shot at you.
