Well, though it is better than the NWU, when it comes to combat, the world ain't made of cinderblock.
The Phibian's answer remains the same; multi-cam. At least the ACU is good for one thing.
Congress is about to order new combat uniforms for troops in Afghanistan after hearing complaints that camouflage that was fine in Iraq doesn’t work so well in a mountainous and often muddy environment.
“Soldiers deployed to Afghanistan have serious concerns about the current combat uniform which they indicated provides ineffective camouflage given the environment in Afghanistan,” lawmakers say in the report accompanying HR 2346, the 2009 supplemental appropriations act.
The bill passed the House of Representatives on Tuesday, 226-202. It heads to the Senate for approval.
There - solution for both the USA and USN .... and the USN could replace 3 uniforms (BDU, DCU, NWU) with one. Easy, low cost, quick, simple ... therefor won't happen.
As a side note; the only service that has it right is the USMC. With both a woodland and desert pattern, they avoid some of the multi-cam compromises, and with their IBA and other "bling" now coming in the coyote color only, they can be used for both without too much loss of utility.
