arrgh...hmm, I very much doubt that, I'm afraid :-\ Perhaps, but I've never encountered such a command...hm.
Maybe give the player a suggestion on how to organise his squads in the briefing? In any case, what if the Player decides he wants the machingunners right beside him instead of out by the peripher, and moves the machineguns around between the soldiers in the briefing screen? Besides, you would limit his creativity
Argh, right. Nope, not aware of any such command, alas.
Wolfrug out.
