When I was in the Marine Corps I shot Sharpshooter, the middle category. It was a fairly average score.
The Marines at the time shot from the 200 to 500 yard line, in what was known as the KD range. The targets’ range was known, and they weren’t moving. The course is really designed to focus on the fundamentals of shooting.
At the 200 yard line you would shoot 5 rounds standing, 5 round kneeling, and 5 rounds standing. For this course of fire you would shoot a round, and they would pull and mark it after each shot.
Then there was a 10 round rapid fire at the 200 yard line. You would fire 2 five round magazines in rapid succession designed to test target retention. You’d do the first 5 standing and the second 5 kneeling. The targets at the 200 yard line were a 12 inch black disc iirc.
Then you moved to the 300 yard line where you would do 5 rounds kneeling slow fire (shoot, mark target, repeat). Followed up with a 10 round prone rapid fire. The 300 yard line is shot at what was called a B-mod target. I don’t remember what the dimensions were, but it represented a man in prone.
Then you’d do 10 rounds at the 500 yard line. This was done in the prone position, slow fire. Target was a Dog target, which represented a man standing in the open.
… I wrote a bit about the scoring system, but to be honest I don’t remember it any more. Half way through my enlistment they changed the system which only helps blur it in my memory.
All firing, at least at that time, was done with a sling but with iron sights. No ACOG or CCO.
The was also a course of fire that was more combat oriented. It was a mere no or no go sort of thing though.
I’m now in the Army and they have a pop target course with targets ranging from 50 yards to 300 yards. There are 40 targets, with 20 from the prone and 20 from the kneeling. I was allowed to use my CCO. After not picking up a rifle for 4 years I shot a 36. Easy as hell with the optics.
