In campaign games, I usually retreat the AO off-map because it has soo little firepower and if you loose it you loose the campaign. But in single-player, I treat it as just another infantry unit. Whether or not to keep it mounted depends on how many AT weapons your enemy has. Obviously, it's not a good idea to mount your AO in a jeep to stay with your armor troops as they encounter ATGMs!
