Here's a prime example of wasteful spending in the military budget. Something utterly simple.
Uniforms.
It used to be easy, four services wearing common uniforms with distinct service dress (Class A if you will) signifying their branch. Two major patterns, woodland and desert, that worked reasonably well. They weren't perfect, but they worked well enough. So, we had a common battle uniform across the services only separated by the service tape and various accouterments. However, the USMC decided it needed to update it's uniform back close to 20 years ago. Spent a lot of money designing and testing three distinct patterns, finally fielded two (desert and woodlands) and they work exceptionally well since computer technology was a part of their design, the first time that had ever been done. The functionality of the uniform was debatable, but overall, it worked fairly well.
The Army, not to be outdone, says they need a new one as well. Because who lets the Marines outdo them, right? Test all sorts of patterns and all sorts of designs. Finally settles on a pattern that doesn't quite work in any environment, though the major colors are supposed to blend into urban, woodland and desert environments. Functionally, the uniforms are quite nice with body armor in mind and pockets in the right places.
Problem is, the camouflage scheme is and continues to be a horrid disappointment. The so called "Universal Camouflage Pattern" royally sucks in damn near every environment. Billions of dollars wasted only to turn around to purchase and issue a color scheme they already tested a decade prior that already showed it was a better camouflage design and already was in use by other nations and in general service in Afghanistan after they figured out their camouflage sucked and the soldiers deserves some form of concealment.
Of course, the USAF can't be left behind. Can't learn from the Marines (two distinct, but awesome patterns) or the Army (extremely functional) and design something that blended the best attributes of the sister services. Nope, let's design a uniform that's basically takes the worst attributes of both the Marines and the Army and add a fourth color, a slate blue for distinctness, in a pattern that doesn't work for ****. Oh, and now we have to use another camouflage pattern for special operations since they flat refused to use that abomination.
And the Navy...never to be outdone, take the digital camouflage pattern of the Marines and makes it into shades of blue...
Yes, blue that blends in with nothing but...water. Helpful like. And by the way, issue two other patterns entirely to the special operations forces because, again, they would refuse to wear that abomination.
Four services, four different combat uniforms, billions of dollars wasted.
