Images have been circulating on Twitter of a Russian Spetsnaz soldier apparently testing out a PKM heavy machine gun with an unusual ammunition-feeding backpack that bears an uncanny resemblance to Jesse Ventura’s alien-perforating minigun from Predator. The backpack, known as the Scorpio, is a product of Front Tactical Systems — and according to The Firearm Blog, it was designed at the request of the Russian military as a method of increasing machine gun efficiency.
