Whenever times get slow, the services change their uniform. The US Army has gone back to Civil War style blue uniforms and rank insignia. I just saw Chief of Staff Gen Ray Ordiero on TV. Instead of the traditional silver stars on the shoulder loops, he was wearing gold shoulder straps of the sort that William T. Sherman and U.S. Grant used to wear.
Only took 65 years for the Army to get back to blue. When the US Air Force got started in 1947 it picked blue for it's uniform. To prevent anyone from confusing Army soldiers with Air Force airmen, the Army promptly switched over to green uniforms. Now the Army is over it's snit with the Air Force and the soldiers are going with two tone blue uniforms.
