Indiana Air NG and (as a previous posting shows) the Texas Air NG show that pilots were actually involved with flying to Viet Nam. There were probably other ANG units that had pilots doing the same thing.
I was coming out of the Infantry and was told to take a position in a Reserve unit or an Army National Guard unit in Indiana. I asked for a waiver because my employment was in Washington DC (where there were NO National Guard or Reserve openings of any kind at the time the area being overrun with draft dodgers of every stripe.)
My entire 4 years Reserve obligation was waived!
Dan Quayle got one of the positions I had rejected. He had not needed to use influence at all at that time!
