When I DEROs's back to the states from 1st Inf Div in Vietnam in June 1968, I was assigned to the Rifle Subcommittee at Ft. Benning as a Staff Sgt. instructor. Lt. Col Whitted was the OIC of the Quick Kill firing program, and had a range on Dixie Road set up for instruction. There was initially an oral block of instruction implementing an assistant instructor firing at a progressivly smaller series of aluminum discs thrown into the air by an assistant. In the grand finale, a two inch disc with a hole in the center plugged with a wad of paper was thrown into the air, and the instructor shot it out of the disc with a Daisy BBgun. The next phase involved one-on-one instruction, with four inch discs, and Daisy BBguns, with the instructor throwing the discs, and critquing the student. When the students completed this phase, they moved on to live fire at pop-up silhouette targets at various ranges. Most students mastered the technique pretty quickly, and hopefully it saved some lives in Vietnam.
