I remember the day I failed to follow the correct steps in disassembly of the 50 cal. Took me several hours to get it right, and I never made that mistake again.
"Though the weight and recoil were a bit much, they actually did ride on pedestal mounts atop standard jeeps."
I know for a fact that firing live ammo from atop of 13 tons of recycled beer cans (M113) will rattle that beast but good. Trying to drive a jeep while Ma was spitting must have been some trick.
There is nothing like the feeling of pushing your chest right up onto the handles of Ma and depressing those butterfly's. You can feel the power roll right through you from your boots to your steel pot.
When I was door gunner we had a CW4 Warrant Officer that installed a Ma Deuce on a Huey D model. This same officer rigged up a way to drop 60mm mortar rounds.
