Based on the infamous Stalag 17 Prisoner of War Camp this obstacle consists of a twisted, tangled web of barbed wire strewn across your path.  The only way to pass is to lay face down in the mud and belly crawl the 40ft under it to (comparative) safety at the other side.  DON'T LOOK UP.

Obstacle Rules

Go under ALL the barbed wire.  There is ample opportunity for overtaking as some of the routes a wide enough for 2 or 3 abreast

Stalag during Winter is easier due to the mud as you can slide along, but you had better be quick as the cold wet ground will suck life giving body heat out of you like a sponge.
