Steps for AI_engage_bug_AT_test.Stratis_2.zip:
1) Load the enclosed repro mission.
2) Order your AT mate to stop.
3) Move through the 3 checkpoints to the waypoint until you see an enemy Ifrit HMG.
4) Reveal the Ifrit HMG to your AT mate.
5) Order your mate to target the revealed enemy.
6) Order your mate to engage the targeted enemy.
7) Nothing should happen at all. There should be silence in the radio and no action taken by the AT mate.
8) Now order your AT mate to move to a position in a third checkpoint marked by a blue arrow with the target and engage command still active.
9) He will say "Engaging" after directly spotting the Ifrit HMG but after a while of movement reports "Negative" and stops the engagement.
10) Experiment with another positions where you move your mate and try to make him engage the target. You may find something interesting.
