And in your daily military news, we take a look at Aleksandr Georgievich Semenov’s patent for a tank gun that will use human waste as a weapon.

Granted in 2009, Semenov’s poop gun patent, is officially titled “Method of Biowaste Removal From Isolated Dwelling Compartment of Military Facility And Device or Its Implementation.” The illustration of the mechanism even shows an illustrated tank gunner’s bare ass positioned over a poop receptacle.

This is how it works: A “military man” poops in a shell casing which is equipped with a charge. He then places the shell into the gun and braces himself. When fired, the shit bomb flies through the air and explodes on the enemy target, coating them in excrement.

As Semenov explained to The Guardian’s Marc Abrahams in an English translation of his Russian patent:

“Except damaging factors, significance of which is secondary in this case, the military psychological positive effect takes place: comprehension of the facts of ‘delivering’ and distribution on enemy territory (on equipment and uniform of an enemy) by the staff as well as the opportunity of informing other soldiers and the enemy about it. As a result, in addition to the basic purpose reaching (full wastes removal) additional military-psychological and military-political effects are achieved.”

Hey, why can’t the military be a little slap-stick when it comes to offensive weaponry?
