You mean making every usf unit better than their counterparts AND giving them free squads makes them overperform?
I predict the moment Officers become "not free" people will complain about 4 Rifle into M20.
I like this idea of Major getting Supervise that Comm_Ash suggested. If it were me, I'd let Ambulance "lockdown" inside the abomination that is the Pizza Base somehow since USF infantry all retreats to one teeny tiny point on the crust so Ambulance ends up in the most obvious and vulnerable position physically possible for USF inviting all forms of rocket artillery and EASY snipes form Pumas and tanks. This NEEDS to get fixed somehow.
