Marines started doing similar a few years back with the Combat Fitness Test. It incorporates a short run in boots 'n utes, lifting ammo cans, throwing dummy grenades, and fireman-carrying a buddy through a small obstacle course. It's a pain in the ass to do on top of a regular PFT but at least it makes sense. Army of course there's still the standard PFT and job-specific standards like you mentioned. For my current MOS the requirement is to get a 4 man team in full battle rattle and move a howitzer muzzle brake a short distance. Simple pass/fail, I like it and it makes more sense than silly bullshit like situps.
