A video of a chimpanzee armed with AK-47 rifle has gone viral on YouTube and has become an Internet sensation.

The video released probably in promotion of the upcoming movie Rise of the Planet of the Apes ( a 20th Century Fox production) shows a group of West African African soldiers handing over an AK-47 rifle to a chimp that strolls into their camp.

It doesn't take the ape too long to realize how to press the trigger but it does take the soldiers some time to realize that the rifle is loaded.

Very soon the chimp starts shooting wildly and the soldiers scurry and duck for cover.

Watch the funny video below to see how the chimp made an ape of the soldiers:
