Taping and measuring only the waist will be an interesting change! I'm happy that height/weight will not be an issue if a score of 540 or higher is attained on the ACFT. People who put in the work to get the bulk, strength, and endurance to perform at a high level should not be penalized.
However, what happens if one of those Soldiers get hurt and end up on a profile? Do they get weighted? What if they end up getting a permanent and can perform at a high level in some while not in others? I understand there's no perfect scenario, I'm just playing devil's advocate.
In the end, normal people will simply need to enjoy more salads, clean proteins, and live like a top tier athlete on a normal person's budget.
