When I retired in 97, name tag (with rank) on left breast, ACC patch on right breast. Squadron patch on left arm/shoulder, wing patch on right. When I was in MAC/AMC prior to that it was the same except we wore the American flag on left sleeve/shoulder. You wore either your squadron or wing patch on the right. I believe that is still current. USAF if that was not obvious. In 92 when McPeak became USAf Chief of Staff, there were huge changes. Among those, MAC became AMC and SAC and TAC were combined to become ACC (Air Combat Command).
