1. With the influx of refugees from the middle east into France there are sure to be a few Sand Pirates in the population.

2. As the hummer drove over the Rubble hill, sand pirates jumped out from behind a bush. They ran with a suicide vest toward the soldiers yelling "Allah Akbar" the hummer machine gun shoots at the sand pirate causing an explosion. The hummer drives off..Noone likes a sand pirate.
