Gaddafi's mercenaries… recruited from all directions?

Colonel Gaddafi did use mercenaries if we are to believe the photos circulating on the internet. Below. we notice men armed with RPGs, like the Chadian rezzous, which include a mixture of very white or Asian men and blacks. This would seem to accredit an all-out recruitment, on the European side as well as on the African side. On board, there are rifles equipped with bayonets. And in the second vehicle, which seems to be more than a machine gun, an automatic grenade launcher (450 rounds / minute, 30 mm, Russian-made type AGS 17 or AGS 30, an Internet user explained to me - see here).
