Marc Hall is an American soldier who got slightly cheesed off when he was told that he’d been so useful on his previous fourteen month stint in Iraq that they wanted him to go back and do it again. He opted to express his pique through the medium of song but the Army, citing artistic differences, has locked him up in a military prison. He seems to have been influenced by a verse from the Internationale:

No more deluded by reaction
On tyrants only we'll make war
The soldiers too will take strike action
They'll break ranks and fight no more
And if those cannibals keep trying
To sacrifice us to their pride
They soon shall hear the bullets flying
We'll shoot the generals on our own side.

The video show his rap interpretation of those sentiments.
