Well, now you might be nitpicking. Camouflage uniforms have to be designed for the environment you intend to operate in. I think the services do spend too much time redesigning uniforms, but the ACU is at least more functional than most.
They literally found out that UCP on the ACU was *inferior* to the old Woodland pattern in pretty much every setting when they went to re-examine the program. The Marines got it right with MARPAT, the Army dumped a ton of money and got something that actually stood out against pretty much every background and was told this from day one of issue by soldiers.
Yeah... Remember the camo uniforms for sailors a few years ago? Pattern involved 2-3 shades of blue.
That would really help people find you if you’ve fallen overboard or the ship was fired on and sunk. Would really help aircraft spot you for rescue. NOT
