There is a big problem with the army that is not discussed much. Because we are so massive personnel wise, our general quality of troop is not going to be as high as you'd think. We need to balance actually getting people in the door and them being able to stay versus making the standards so high we lose members with seniority or specialities.
For example, a CID agent(detective) and combat photographer needs to score 60%; cooks, combat medics, and band members all have to score a 65%; and truck drivers need to score 70%.
Can you see why some there is some discrepancy over how these scores were chosen for each MOS? Had in age/injuries sustained over a career and you start seeing reductions in force at the upper levels, which is no good.
Also of note is the exercise that really hurts females (leg tucks) requires a good deal if upper body strength, which females generally lack compared to males. We replaced an abdominal equalizer (situps) with one that disfavored one gender, right after already assessing upper body strength.
Another big thing that
@Marauder06 hit on perfectly is lack of training. Quite simply, the army is dogshit when it comes to PT for most of the force. I can't tell you how many times I showed up for the day and was told "Hey cookie, so and so is at sick call, so you lead muscular endurance/strength/speed PT today."
Units very rarely train on the pull-up bars, and if they do it's rare to have someone who actually knows what they're doing leading it.
Changes to the ACFT I'd like to see that my improve it:
------------------------
Bring back age categories for the run and sprint.
These seem to be the two events that have the biggest connection with age.
------------------------
Create weight categories or % for the deadlift. A 120# female pulling 200# should not be worth 70% when my 195# self also scores the same for that weight.
I remember something from a few years ago that said the "average Ranger" was 5'9 and 175#, so let's just use that at a basis.
That would make the max deadlift 10# less than double bodyweight, the 70% score 25# (14%bw) heavier, the 65% basically bw, and the 60% 30# (20%bw) lighter.
So a "BW% scoring sheet" might look like:
100- 2xbw
70- 1.25xbw
65- 1.125xbw
60- 1xbw
No reason not to conduct a height and weight before the PT test, put that on the cards, and then use a formula to calculate the scores.
Would it take a bit longer? Yes, but it's a much clearer picture of strength.
------------------------
Replace the leg tuck with either hanging knee raises (if the army cares about grip strength) or rowers (if they care about upper/lower ab strength).
Mara already provided scoring for rowers: 1 per rep.
Hanging knee raises I would double the scale, ie minimum 2/6/10 max 40.
