JFK Assassination Plus General Discussion And Debate / Re: Applying Logic and Critical Thinking to the JFK Assassination
« Last post by Michael T. Griffith on June 22, 2026, 01:38:11 PM »I figured out why my sources on the Marine Corps rifle qualification standards differed somewhat in the allotted times for the slow-fire and rapid-fire phases: the source I'd been using was for the 1943-1955 standards, whereas the source I found last week includes the 1943-1955 standards and the 1955-1968 standards. Oswald was in the Marine Corps from October 1956 to September 1959.
The 1955-1968 rifle qualification standards prove it is untenable to cite Oswald's Marine Corps rifle scores as evidence he could have performed the alleged shooting feat.
First off, we must keep in mind that when firing for qualification in the Marines, Oswald was using a superb semi-automatic rifle, either the M1 or the M14 (the M14 replaced the M1 in 1957, but the M1 was still often used for rifle practice and qualification). Thus, whether using the M1 or the M14, he had no bolt to manually operate--he just had to aim and squeeze the trigger. This is a huge difference compared to firing a bolt-action rifle where you have to manually operate the bolt for each shot.
Second, when firing for qualification, Oswald was firing at stationary targets, targets that he had practiced against several times beforehand.
Third, and this is a crucial point, to score a hit at 200 and 300 yards, Oswald had to hit a black circle on the target sheet that was 10 inches in diameter (10 inches wide and 10 inches tall), nearly twice as wide and 22% taller than the average male head. The average male head is 5.5-6.0 inches wide and 7.8 inches tall (from bottom of chin to top of head). To score a hit at 500 yards, Oswald had to hit a black circle that was 20 inches in diameter, more than triple the width and more than double the height of the average male head.
Fourth, even in the two "rapid-fire" phases, Oswald had 5 seconds to fire each shot. For the four slow-fire phases, he had 72 seconds (1.2 minutes) to fire each shot. Let's look at all the times for all the phases:
Stage One-Slow Fire
200 yards
12 minutes
10 rounds
Firing rate: 1.2 minutes per shot
Stage Two-Slow Fire
Stage Three-Slow Fire
300 yards
6 minutes
5 rounds
Firing rate: 1.2 minutes per shot
Stage Four-Slow Fire
500 yards
12 minutes
10 rounds
Firing rate: 1.2 minutes per shot
Stage Five-Rapid Fire
200 yards
50 seconds
10 rounds
Firing rate: 5.0 seconds per shot
Stage Six-Rapid Fire
300 yards
50 seconds
10 rounds
Firing rate: 5.0 seconds per shot

Fifth, to qualify in the "sharpshooter" category, Oswald only had to achieve a score of 210 out of a possible 250, with each shot counting as 5 points. This means he could miss 8 of his 50 shots and still qualify as a "sharpshooter"--and, again, this was while using a semi-automatic rifle against 10-inch and 20-inch targets that he had practiced against several times beforehand.
Sixth, Oswald was always firing from a level position at Marine Corps rifle ranges, and never from an elevation, not to mention an elevation of 60 feet. Thus, he never had to worry about the high-low factor when firing from an elevation. It is doubtful he ever even heard of the high-low factor.
Clearly, his Marine Corps rifle scores tell us little about his ability to use a bolt-action rifle from 60 feet up while firing through a half-open window in cramped conditions and to score 2 hits in 3 shots in a 14 x 4-inch area in no more than 11 seconds and to score his 2 hits in 5.6 seconds (since everyone agrees the alleged lone-gunman's first shot missed).
