This ticket is regarding the AI's inability to change stance in order to shoot over an obstacle he is already behind. If an AI team mate is manually ordered to move behind some form of cover, he cannot utilize the it effectively. Consider the following example:

If an AI is in a "Combat" state, he will often lie prone no matter where he is - this is okay. However, if the unit is behind a short obstacle he will never change stance to engage enemies on the other side. The ideal behavior is the unit change stance temporarily to shoot enemies if a squad mate has called them out and the squad is in a combat state (unless of course you explicitly set the AI's stance).

With the current implementation, even if you give the unit an explicit order to engage, he will change stance but then also move out of cover, even though he had a clear shot as soon as he went into a crouch.
