Dunno quite what you are talking about, but if you had ever seen the rotating drum feed trays of 20mm the gun pod used, that had to be synched perfectly with the gun, it was a clusterf**k. Hughes Aircraft really sold the navy a pig in a poke with that one.
Never got to work with the miniguns the army had. Had an army gunship stop at our forward rearm pad and ask us to fix their gun. We just looked at each other. Give us a day or three and we could figure it out, we were ordnance guys after all. We did stock minigun ammo and it was highly prized as primo 7.62 belted stuff.
And after a hot lz, the ham and lima was hot enough for hot chow!
