Hello all, this is a question that may have been answered before, so forgive the double up. I actually saw this question on another site with no reply and I thought it interesting...and looking thro' my references, I could not find the answer. Well here goes. What did the .50 cal and .30 cal gunners stand on to fire them on the LVT4? Perched on the sill of the access areas to the cab for the .50cals would be uncomfortable to say the least. In the later LVT the troop benches would be a help for the .30 cal gunners.
Well the .50 cal's were meant to be anti aircraft guns, so they could be fired into the air by gunners standing on the floor of the compartment, like these:
Otherwise I suppose a large ammo box would do the trick.
