In the late 2000s timeframe much of the medical community was divorced from the MAJCOM level (with the major exception of the readiness mission) and given to a new FOA called AFMOA. It makes sense for support functions to be managed at a FOA level instead of MAJCOMs because medical is medical, finance is finance, etc-whether medical is at a tanker base or a space base the MTF still functions the same way.
