Seriously, one has to be a total bolo to not get an award for marksmanship. Everyone walks through the training and if orders are followed and one is not a total klutz, the award is Marksman "on a marksman/sharpshooter/expert scale."
During his Marine Corps service in December 1956, Oswald scored a rating of sharpshooter (twice achieving 48 and 49 out of 50 shots during rapid fire at a stationary target 200 yards [183 m] away using a standard issue M1 Garand semi-automatic rifle), although in May 1959, he qualified as a marksman (a lower classification than that of sharpshooter).

While he was at San Diego, Oswald was trained in the use of the M-1 rifle. His practice scores were not very good, but when his company fired for record on December 21, he scored 212, 2 points above the score necessary to qualify as a "sharpshooter" on a marksman/sharpshooter/expert scale. He did not do nearly as well when he fired for record again shortly before he left the Marines. He practiced also with a riot gun and a .45-caliber pistol when he was in the Marines but no scores were recorded. [1]
