Funkertactical posted up a video of U.S. Marines cross training with French Foreign Legion soldiers.
According to Funkertactical:
In this video filmed by SSgt Tanner Iskra we are witnessing incredible footage of U.S. Marines and The French Foreign Legion cross training on each other’s small arms weaponry. Filmed at Camp des Garrigues in France this live-fire exercise involving the Special Purpose Marine Air-Ground Task Force (SP-MAGTF) Crisis Response from 3rd Battalion, 8th Marine Regiment and Legionnaires from 2nd Foreign Infantry Regiment of France’s 6th Light Armored Brigade offers an incredible look at the technology and operations of some the world’s best small arms.
Looks like they filmed some of this with a GoPro weapon mounted and possibly a Contour helmet mounted.
