Desperate for weapons in their fight against the Syrian government and Islamic State enemies, the Free Syrian Army have constructed a DIY tank that uses a game controller to aim its main machine-gun. This short video documentary from Vocativ shows how the Aleppo-based militias created the tank out of a pickup truck and scrap metal, making use of game technology to aim and fire weapons.

Correction: A previous version of this story misidentified the game controller as a PlayStation controller.
