I must have the wrong end of the stick yet again...…..
I've always assumed that anything military, or wearing low-viz plumage was there as something that was A) expected to go into harms way as many times as possible before becoming collateral damage and B) have a very high attrition rate several orders of magnitude higher than broadly equivalent civilian kit.
Likewise the folks who sign up to sit in, sit on, or wear low-viz plumage themselves.
Seems today that they're all just too expensive to let them be used for their intended purposes.
