As I recall, the US Army airborne troops had the M56 SPAT (self-propelled anti-tank) gun with a 90mm gun (no armor) and the Marines had the M50/M50A1 ONTOS anti-tank weapon with six 106mm recoilless rifles. Those Dominican tanks from Sweden were Spam in a can when the rant into a 90mm or 106mm anti-tank round. The Dominicans committed their tanks to battle in piecemeal fashion and did not use them effectively. The airborne soldiers and Marines turned them into flaming junk piles.
Wasn’t the Ontos and M56 on the same chassis? Those Ontos compartments were tight; too small for me. :<}
Even the M48s were too cramped. Amtracs had some room in them-—— just hoped they didn’t sink, Ha!
