There is a version of the M113 with a cherry picker launcher mounted on it. It allows you to go into hull defilade and then raise the launcher. Something like that would have made the Ontis neet for airborne or heliborne troops.
An elevating mechanism positions the launcher platform into reload and elevated positions. The system is capable of firing two missiles without reloading and carries ten TOW rounds in the missile rack. Maximum protection is provided the crew during reload.
