Another of the same C-130. Another of the same C-130.Judging from the big ol’ cannon sticking out of the side, that’s an AC-130. Those are very bad news for adversaries on the ground.
The main gun should be a 105mm howitzer, I’m having trouble seeing more but there should be at least one 40mm Bofors also. They used to have 20mm rotary cannons, but not any longer as they were considered too short-range.
