The conceit of adding starch back in later to make something look new is already funny; to do it routinely is absurd.
Of course anyone who has been in the military of any country knows "absurd" is a pretty frequent factor.
I'm not certain that "absurd" is a strong enough word for it.
I was frequently reminded of Tevye the milkman singing "TRADITION!" at the top of his lungs. The only thing worse than participating in absurd and obsolete traditions as an insider is to be forced as an outsider to completely ruin an otherwise rational workflow in order to accommodate them.
If you have ever taken calipers to a software-generated printout, in order to compare it to a paper form that was last revised in 1980, and printed in bulk ever since, you deserve to wear starched underwear.
True absurdity in the military is an orthogonal axis and runs from, indeed, vestigial rules such as you imply, all the way up to ordering enormous weapons systems the military doesn't even want simply for political reasons.
But we'd also have viable gunblades and dozens of rare uniform crafting recipes, and our military would be well prepared to repel zombie pandemics, space-alien invasions, and goblin sieges, as well as to defeat S-class daikaiju.
...So there is something to be said for letting experienced professional soldiers run the military. They might know what they're doing behind the facade of repetitive busywork, like Mr. Miyagi teaching Daniel-san karate. Or they might not. It's hard to tell from where I sit. A lot of the budget is not freely auditable by the public, and I have certainly seen firsthand a very small portion of it totally wasted on absolute nonsense.
that said, I did see that Avengers End Game got the 70's fatigues right. And also the hideous baseball cap we had to wear.
Well, you were going to be fighting in western Europe and living in NBCW suits all the time anyway....
I'm skeptical that there's much utility there, but maybe someone better informed than me can chime in.
Velcro pockets, though... those were terrible. Both in durability (their "grip" would weaken over time) and noise.
