Heh...Marine envy in the Army
It appears that Army's change of thier dress uniform was due to Marine uniform envy: USMC Wannabe Blues.
All this is the result of longstanding "uniform envy" soldiers have had for marines. The USMC has always sported the most impressive dress uniform, and young enlisted marines were glad to spend at least $300 to buy themselves one. The marine "Class A" uniform is also green, but a darker green, and the jacket is worn with a belt. This looks much snappier, and many soldiers have suggested something like this for a new army Class A uniform. But many career army types have been campaigning for a spiffier Class A uniform, and something in blue, preferably with a belted jacket. But instead of a new uniform design, the army simply made the current dress blues the new Class As. The dress blues have been around for a long time, and have a good reputation. That doesn't mean that a belt cannot be added down the road. The important thing right now is to dump those hideous green Class As, which have embarrassed several generations of soldiers.
Here's the Army dress blues (now service uniform) in comparison with the Marine dress whites(the blues would be with the blue trousers):
Apparently, I missed the Air Force and their new dress uniform:
Alright, I've had my fun. I now await all the "dumb Marine" jokes my dear service brothers and sisters are going to unleash.
