Guns of Arabia

Inspired by Harry Turtledove's Guns of The South, but instead of neo-Nazis going back in time to the American Civil War, it's members of ISIS going back in time to 732 A.D., a few months before the battle with Charles Martel. They aid the leader of the invasion, Abdul Rahman Al Ghafiqi, with AK-47s and rocket launchers.
