When I got commissioned in an AROTC unit, we were told the first salute had to go to an enlisted soldier and it couldn't be a cadet, so we all simply left the chapel where we were all commissioned and may our way to our favorite NCO Cadre from our unit and received our first salute. I have a photo of that. When may DH was commissioned at USMA, his younger brother was enlisted in the Marines and flew in for the ceremony and gave my DH his first salute. Later on when my BIL was commissioned in the Marine Corp, my DH gave him his oath. My DD, had her younger brother who was a USMA cadet give her her first salute after my DH performed her commissioning ceremony. When my DS was commissioned he had his fiancee, who was a cadet give him his first salute. These are such treasured memories.
