The aircraft carrier

You can't get IN the turret, but you grab onto one of the huge barrels and quickly rip it out of the turret with your robot. Hydraulics hiss and servos whine, but the turret's barrel comes off the turret with some screeching. You now have a 'bat' which is the hulking steel turret shaft with some leftover machinery, the trigger assembly, still attached but definitely not functional.
