Not to disparage anyone but in the case of the Marines they maintain this standard throughout the ranks. Every General to every musician must complete a PFT every year to remain in the Corps. They can find people with both smarts and physical toughness. Other services have less strenuous requirements.
Standards exist for a reason and should not be watered down for anyone. My point was that there needs to be a way for people who want to serve to be given that chance in some way.
The US Army conducts its APTF twice a year, MANDATORY.
All ranks, all MOSs.
But, I suppose if something’s repeated often enough...
