I know they are CiC but never having served means it's mostly an honorary title like British royalty gets for just being born.
Obambi was particularly bad because his first attempt, at the Illinois war memorial with tammy duckworth, looked like a salute from Bennie Hill.
Don’t recall seeing Trump fail to salute. Maybe once by mistake, quickly remedied? That’s all that comes to mind. Not an offender AFAIK.
