I find it interesting that you can serve at any height between 4'10" and 6'8" but there's one physical fitness standard that evaluates everybody.
There aren't weight classes like Boxing, Wrestling, or MMA.
If we look at other situations where people are evaluating "measurables" related to athletic ability, check out the NFL Combine.
In 2025, the fastest 40 yard dash times are:
Cornerback - 4.28
Offensive Lineman - 4.84
In 2025, the max bench press reps (225 lbs) are:
Offensive Lineman - 33
Cornerback - 21
https://www.nfl.com/combine/tracker/live-results/In my opinion, there should probably be a minimum level of "measurables" achieved to serve in the Army.
And there should probably be a different level of "measurables" for serving in different MOS.
I think back to when I attended Army ROTC Advanced Camp and turned in one of my fastest 2 mile runs ever at 14:45 which was considered slow by Texas A&M expectations. I was standing there for more than five minutes while we waited for a 27 y/o prior enlisted female to finish her "passing" 2 mile run which took her more than 20 minutes to complete.
Point is, I don't know that there is a correct answer but it's also kind of silly to think that all the different types of people we take into the Army are going to have their physical fitness evaluated in any serious way other than to ensure they can achieve very minimum standards - like on civilian job descriptions where you see - must be able to lift 25 lbs, etc.
I could see a system where the requirements are something like:
Must be able to run a 20 minute 2 mile to be a Soldier
Must be able to run a 16 minute 2 mile to be in Combat Arms
Must be able to run a 14 minute 2 mile to be Infantry
Or whatever standards you want to make (I just made those numbers up to illustrate the point)
It probably doesn't make much difference whether the fuel handler filling an Abrams Tank can run to the end of the block and back. But, they definitely need to be able to climb in and out of an 8x8 Fuel HEMMT. Maybe there should be some sort of climbing test for that MOS.
