I don't know how I missed it, but the Army is changing uniforms. When I started soldering back in the mid '70s, we wore the Army Green Service Uniform. Also know as "Class A", it was the uniform you wore if you were in an assignment that called for "coat and tie" dress. It looked like this:
I wore that uniform infrequently, for 25 years. If the detail required a more formal attire, such as at a function where one might wear a tuxedo, the Army Blue uniform was specified.
I always thought that it was a goo looking uniform. But, I thought that it had long ago been relegated to museums and re-enactorrs. When I was in officer training back in the early '70s we had one officer who found the WWII version in a second-hand shop and bought it. He got permission to wear it occasionally to show the children what the WWII uniform looked like.
As long as they don't resurrect the universally hated khaki uniform. Gawd, how I detested that uniform.
