Didn't you see the vid? It will somehow save the Navy millions in uniform allowances !
Pretty sure there's some fuzzy math there, since the uniform allowance is not based on how many times a particular individual has to replace his uniform, eg MM3 Smith doesn't get more allowance to replace his NWUs than ET3 Jones just because Smith's work makes them wear out more quickly. And I don't think that the allowance is going to jump down just from replacing aquaflage with woodland or desert camo.
However, MM3 Smith doesn't wear his aquaflage when he's working normally. Most of the snipes that I remember had the ships issued fire retardant coveralls.
