Remember one of the happenings that started the ball rolling on this issue -- there is a group that is starting up a contract schoolhouse to teach fighter lead-in training to foreign air forces in F-5s.

As part of the deal, the IPs were going to have to go get CFIs so they could legally teach in civilian aircraft (the privately owned F-5s).

Nobody understood the opposite part of what you mention above -- why would someone teaching dogfighting in a jet need to know how to teach about carb ice?? They wanted to have their current military IP qual be good enough to teach at the F-5 school without the requirement to go learn to teach someone to putt around the pattern in a piston GA aircraft.

So, with some important connections with people at the FAA, the proprietor of this outfit lobbied to get CFI equivelency for current military instructors.

There is obviously a lot more that has gone into this argument, but that is what started the ball rolling.
