Retired Generals and Admirals who never won a war adorned with 300 times the medals, ribbons, and camouflage than that worn by American military leaders in WWII, who actually won a war. See Eisenhower, Halsey, Nimitz, Patton, King, et al.
Patton has elaborate decorations in a number of photos and portraits, but your point is well taken. Eisenhower and Bradley were far more humble in their professional appearance.
Decorations for completing basic training, tech school, NCO training, community volunteer work, and many others don’t make much sense.
