If enemy squad uses the waypoint "SEEK AND DESTROY", then this AI squad should moving in this direction and trying to find and neutralize the enemy, because this squad must "SEEK and DESTROY". But for Arma AI, it possible only on the terrain map!
If the player will hide inside any building, then AI is not looking player inside buildings!
AI will be a run and scream on the destination point, but did not go inside.
It is not realistic for the game. This is great nonsense!
Yes, perhaps the AI can skip the one-two building, if the enemy is not detected. But if the enemy detected!?
Please Note! Even if a player shoots out of this building (thereby revealing itself) then the enemy AI still will not try penetrate into the building! Why!??
This behavior of the AI is not realistic and double silly!

Please teach the AI to assault the building, if this AI uses waypoint "SEEK AND DESTROY"! After all, the AI must find and destroy!
If AI-squad sees that a player located inside a building, then this squad should penetrate into this building.
Each building usually has several doors.
I think, during the assault, the AI should go into each door simultaneously and try clean this building!

BIS can do a special action -"ASSAULT" for every squad leader of squad in the actions menu.
For example, if the player is a commander moves the cursor to the building where enemy detected, then let this commander will be able use to assault/cleaning command only for this building. This will cool!
In this case the player or the AI, under special conditions can give the order to enter the building and to clean it.

This detail can be a great addition to tactics of the player-commander and for realistic AI behavior (if he uses waypoint "SEEK AND DESTROY")
