Varför heter det minigun?

It must be noted that M134 miniguns are very rarely used for infantry applications; photos of M134 installed on standard light tripods are almost universally from some 'Civilian' events such as Knob Creek shot in USA, where people can fire a number of legally owned full automatic weapons just for fun. Military has no place for a 30-kg weapon (less mount and batteries) with extremely high ammunition consumption rate in a 'man-portable' class of small arms. Prospects of using M134 in 'Hollywood-style' are even less realistic, not only because of aforementioned properties (heavy weight and unnecessarily high rate of fire) but also due to the extremely high recoil force - at just 3,000 rounds per minute the Dillon Aero M134D minigun generates average recoil force of 150 lbs / 67.5 kg, with peak recoil reaching 300 lbs / 135 kg.

In the year 1987 the movie "Predator" (starring A. Schwarznegger) hit the screens. One of the most impressive scenes was the one where the US Commandos, led by "Dutch" (Schwarznegger), attempted to fight back the alien Predator. One of Commandos was armed with the distinctive weapon, a 6-barreled rotary Minigun, fed from backpack ammo box. This gave the impression that the Miniguns can be used for infantry support. It must be noted, that in this movie a special, blank firing version of the Minigun was sued. The electric motor was powered via cable, hidden in the actor's pants, and the actor had to carry bulletproof vest and protective mask to avoid injuries from the fast and violently ejecting empty cases. Had this gun being fired using real ammunition, the actor would ended lying on his back, being forced off the legs by the violent recoil. The "backpack" ammo capacity, also, could be worth only several seconds of fire. lets calculate: 2 000 rounds of 5.56mm ammo will weight about 25 kg (55 lbs); 2 000 rounds of 7.62mm will weight about 2 times more, making such load almost impossible to carry on foots. yet this load of ammo will worth only 20 or so seconds of fire. Add some powerful batteries to power electrical drive of about 4KWt (4+ horse-power), and the bulk of the gun itself, and you'll see that even the strongest man won't be able to carry this load, less to fire it with any chance to hit, due to extremely powerful recoil.
