this is actually a prototype for a tank silencer. you see, you wanna fuck up something silently, you stick the cannon in this bitch and instead of "BOOM" you hear "pew."

i want to see this thing in action.

artillery silencer on german shooting range near a town called Meppen (germans really like bitching about noise)

Penis.

There, i said it.

Damn you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
