Today was a good day / I jumped a car with my AK.
In most places in the world, it's easier to find a jumper cable than it is to find two AK-47s. Apparently, that's not the case wherever this video was taken.
The video, apparently taken somewhere in the Middle East, shows what appears to be members of the local military or militia jumping a car using two AK-47s. The steel barrel and wire stock are sufficient to carry the electrical charge from one car to another. The rifles aren't long enough, so each man is also holding a long piece of wire that is touching his AK. After a few seconds you can hear an engine rev and the men stop.
This is not a recommended way to give someone a jump. If the AKs had touched metal on metal, it could have been very bad for everyone. AK-47s are for shooting, not car repair. Be safe and keep a pair of jumper cables handy.
