XCOM 2/ADVENT Officer

''"The officers seem a little more capable than the grunts. We're not sure whether to chalk it up to training or stricter mind control." ~Central Officer Bradford''



Throughout the game, many alien pods are led by ADVENT Officers. These deep red enemies have more HP and higher aim than the troopers they frequently lead. They also possess a single grenade and a single supportive ability: Mark Target. On Commander and Legend difficulties, they have innate 10 crit on their weapon. They are sometimes referred to as ADVENT Captains.

Skulljacking an officer will kill it instantly and spawn a codex. Doing so at least once is required if you want to win the game.

Abilities
Mark Target: Costs 1 action and does not end turn. The Captain marks an XCOM unit within its squadsight vision range. Can only be used on a target which is not already marked. Shots taken against a marked target have +10 aim. The Mark lasts for 2 turns and has a 2 turn cooldown. A mind-controlled ADVENT Officer cannot use this ability.

Appearance
ADVENT Officers can only appear as pod leaders except on retaliations, where they may be led by stun lancers.

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 Officer 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.
