We never stopped wearing blue.
We just kept it in the dress uniform.
But, you’re right that we have a problem with career officers (Shineski, et al) who keep changing things to keep their careers alive. “Publish or perish”, as they say.
Most soldiers want to return and STAY with those uniforms that defined the Army in the WWII era.
I agree that the WWII uniforms were the best the Army ever used, but right after the war - as one commentator described it - the Army adopted a cheap imitation of the Wehrmacht’s uniforms.
