In the late 1950's we formed a Battalion of these. Each had a crew of three, and 6, count them, 106mm Recoilless Rifles. You can consider it "The Worlds Biggest Shotgun".

I’d hate to have been the loader for one of those.
from your link:
“The Ontos carried the beehive round that sent out a hundred darts per firing to clean out a jungle of its enemy. There was no other weapon that could clear a jungle for a depth of a ¼ mile like the 106mm recoilless rifle using the beehive round. “
I love Ontos. Load Sunday and shoot the rest of the week. Plus the major headache a 106 recoilless round will give you is guaranteed to spoil your whole day! Yours is a great pic. By the time I enlisted (67) they were on their way out if not totally gone.
