However, McPeak is best remembered by many current and since-retired Air Force personnel for the sweeping changes he made to the Air Force's service dress uniform, especially for commissioned officers. Worn by more personnel during most duties, the new version was a radical departure from the earlier version, which was essentially the same design as the then-U.S. Army service uniform (the U.S. Air Force was originally the U.S. Army Air Corps and then the U.S. Army Air Forces), but with fewer insignia. Because of the new uniform's resemblance to both commissioned officer's uniforms of the U.S. Navy and those of commercial airline pilots, the McPeak uniform was said to be unpopular with Air Force service members. Some uniform changes were subsequently reversed by his successor. The basic redesign continues to be worn to this day, but the navalized sleeve braid rank insignia for officers was eliminated and name tags reinstituted, albeit in silver metal versus the blue plastic nametags worn with the earlier uniform, with the blue plastic nametags still worn on service uniform shirts. McPeak's original concept of simplifying and toning down the various devices and insignia pinned to the uniform has gone by the wayside, with nearly all USAF personnel wearing at least one, if not two, three or more metal insignia with their dress uniforms.
