Nfld Spr, when you go into action/come under contact, your air sentry should be pulling in. The delco turret with TOW has one launch tube on either side of the turret. You would not be able to stow anything on the back of the turret due to BBDA.
To fire TOW, the vehicle has to remain stationary (and preferably in a hull down position) anyways. So the air sentry can duck his arse back inside.
