I made the statement Punisher referenced in the first post.
Ill give a little scenario.
I went with a SGM, an E9, who had been in the Army around 20 years and two CPTs who had been in about 6 to the pistol qualification range. You fire something like 30-40 rounds. It is set up in tables of fire. Some walking some stationary. None of the shots are ridiculous. The two CPTs scored perfect. I do not feel it was out of the ordinary either as I could have done the same I am sure. The SGM scored like ~5 hits. He had at least 3 times as many years in the service and what could be percieved as 3 times as much experience yet he did terrible. Military service does not guarantee being an expert with a firearm.
I also had a Plt SGT who couldnt qualify with 23 hits out of 40 on the regular rifle range. It took him all damn day everytime we went to qualify. This man was "Ranger" qualified and had been in Ranger BN.
