No dobra, wstyd jest

Pomieszalem fakty.
Despite popular depictions of modern gatling guns (usually the M134 Minigun and variants thereof) as handheld weapons, such usage is technically impossible as the combined weight of the weapon and requisite ammunition is much too great for personal use.
For feasible combat use, a large ammunition supply is required; depending on the rate, several hundred to a thousand or more rounds could be necessary. Furthermore, the recoil is too forceful for a single person to handle. In the Arnold Schwarzenegger film Predator, Jesse Ventura's character had to be propped up during sequences where his M134 was fired, even though it had only blanks.
Another important factor is the power consumption of most modern systems. For instance, an M134 at maximum speed would require 130 A for its 28 V DC/115 V AC electric motor, the equivalent of a few car batteries.
