That is a window gun not a fixed gun, which you see on pretty much all transport helicopters.Clearly Not. He meant more as door mounted defense. Fixed Gatling guns have a use but Hollywood and Video games fat it wrong. Such a weapon would be better suited to a light nimble attack platform like the Z11.
The gunner needs to be able to manipulate the weapon that means charge it load it swing it about. It has to be in arms length.I am waiting to see general purpose MGs or miniguns mounted on these Sino Blackhawks.
