2 things to consider
1. The Major is a member of the Air National Guard, not the regular US Air Force. The National Guard has 2 components; Air National Guard and Army National Guard. As you can imagine the Army Guard provides ground combat units for the US Army and the Air Guard provides air units for the USAF. But the Guard also has a mission to respond to the state's governor for emergencies and head of the National Guard for each state is the State Adjutant General. The AG is appointed by the state's governor since the Guard's first responsibility is to the state. By its very nature, the National Guard is much more political organization than the Active component. The AG is usually a long serving Guardsman from either the Air or Army Guard
The Missouri Guard AG is an Army NG member. This could be an underlying reason for the major's actions. I recall in the 1990s the AG for New York was an Air Guard general. At the time I was working extensively with the New York Army National Guard on a project. From the brigade comamnder on down they were very bitter about the State AG since there was a perception that the AG favored Air Guard offciers for key appointments over Army Guard members. This was of particular import to these guys because their proud Infantry brigade was going to be reorganized into an area support group...with the full support of the governor and State AG. For the state, this would make sense since it would provide better resources for state in times of emergencies. For the Army Guard guys this would force many to change from Infantry to Quartermaster, MP or Engineers.
And it would end up closing out a unti with proud traditions and comabt records from WW 1 & 2.
I am not saying this what is the case now but perhaps there is some of this the major's actions.
2. I am with others that the dollar cost is low. Perhaps it is the amount which he has lost in flight pay since he is no longer on flight status and is merely an attempt to even out his salary.
Just some thoughts from the lunatic fringe.
