I watched a film recently but can now only remember the following scene and it’s driving me crazy.

US soldiers are in Afghanistan and they play the locals at buzkashi (where they are all on horseback and fight over a goat/sheep carcas and have to take it down the other end to score a point). I think the team of Afghans they are playing against includes someone who has been trying to kill the soldiers or is leaking information and the game gets nasty!
