“To become qualified as a sharpshooter the Marine Corps is of the opinion that most Marines
with a reasonable amount of adaptability to weapons firing can be, so qualified.
Consequently a low marksman qualification indicates a “rather poor shot” (Vol 19 pages 16-18)

What do some actual Expert Marine Officers say about Oswald's shooting abilities.
Mr. SPECTER. Based on the tests of Mr. Oswald shown by those documents, how would you characterize his ability as a marksman?
Sergeant ZAHM. I would say in the Marine Corps he is a good shot, slightly above average, and as compared to the average male of his age throughout the civilian, throughout the United States, that he is an excellent shot.How about the question of Oswald's capabilities to take the head shot?
Mr. SPECTER - I now show you a document marked as Commission Exhibit No. 902, which characterizes what was believed to have been the shot which struck President Kennedy in the head at a distance from rifle in window to the President of 265.3 feet, with the photograph through rifle scope identified on the document being the view which the marksman had of the President at the time the President was struck in the head, and I ask you again for an opinion as to the ease or difficulty of that shot, taking into consideration the capabilities of Mr. Oswald as a marksman, evidenced by the Marine Corps documents on him.
Major ANDERSON - I consider it to be not a particularly difficult shot at this short range, and that Oswald had full capabilities to make such a shot.Then lastly, what was the difficulties of Oswald with his equipment of taking the Dealey Plaza shot?
Mr. SPECTER. How would you characterize that, as a difficult, not too difficult, easy, or how would you characterize that shot?
Sergeant ZAHM. With the equipment he had and with his ability, I consider it a very easy shot.
