For years i was the senior firing range advisor to the Saudi National Guard. One of the non-modernized battalions that used our ranges was the remnant of a princes private army that was integrated into the national guard: They were all from the same tribe. Their automatic rifle was an updated quick change barrel version of the BAR, the FN-D; chambered for 8mm. Their machinegun was the MG42/58. Their rifle was the FN model 1950.
The soldiers from that unit were the best military marksman i have ever seen.
