As of now, commanding an AI squad may sometimes be considered a nightmare. If you get attacked, it is literally suicide trying to get your squad to a better formation, to open fire and to go prone/crouch.
I often find myself in the situation of desperately pressing 1~9 just to find out which one was the one that had the "GO PRONE" option. Of course, I could memorize it, but in middle of battle, I could care less about this stuff.
Not to mention I have to drop either WASD OR my mouse in order to select F1~F12 or 1~9, rendering me completely useless as I command them.
To make things worse, you cannot customize these buttons, so you are stuck with them.
The current UI for squad command is outdated. Remembers me of the stuff there was in the 1990 ~ 2000's. (No offence intended.)
