I consider it a real advantage, particularly at the range of 100 yards, in identifying your target. It allows you to see your target clearly, and it is still of a minimum amount of power that it doesn’t exaggerate your own body movements. It just is an aid in seeing in the fact that you only have the one element, the crosshair, in relation to the target as opposed to iron sights with aligning the sights and then aligning them on the target.[C4-770] Characterizing the four-power scope as “a real aid, an extreme aid” in rapid fire shooting, Sergeant Zahm expressed the opinion that the shot which struck President Kennedy in the neck at 176.9 to 190.8 feet was “very easy” and the shot which struck the President in the head at a distance of 265.3 feet was “an easy shot.”[C4-771] After viewing photographs depicting the alinement of Elm Street in relation to the Texas School Book Depository Building, Zahm stated further: This is a definite advantage to the shooter, the vehicle moving directly away from him and the downgrade of the street, and he being in an elevated position made an almost stationary target while he was aiming in, very little movement if any.[C4-772] Oswald’s Marine Training In accordance with standard Marine procedures, Oswald received extensive training in marksmanship.[C4-773] During the first week of an intensive 3-week training period he received instruction in sighting, aiming, and manipulation of the trigger.[C4-774] He went through a series of exercises called dry firing where he assumed all positions which would later be used in the qualification course.[C4-775] After familiarization with live ammunition in the .22 rifle and .22 pistol, Oswald, like all Marine recruits, received training on the rifle range at distances up to 500 yards, firing 50 rounds each day for five days.[C4-776] Following that training, Oswald was tested in December of 1956, and obtained a score of 212, which was 2 points above the minimum for qualifications as a “sharpshooter” in a scale of marksman--sharpshooter--expert.[C4-777] In May of 1959, on another range, Oswald scored 191, which was 1 point over the minimum for ranking as a “marksman.”[C4-778] The Marine Corps records maintained on Oswald further show that he had fired and was familiar with the Browning Automatic rifle, .45 caliber pistol, and 12-gage riot gun.[C4-779] Based on the general Marine Corps ratings, Lt. Col. A. G. Folsom, Jr., head, Records Branch, Personnel Department, Headquarters U.S. Marine Corps, evaluated the sharpshooter qualification as a “fairly good shot” and a low marksman rating as a “rather poor shot.”[C4-780] When asked to explain the different scores achieved by Oswald on the two occasions when he fired for record, Major Anderson said:
