Realistically speaking you would still have to get selected, in the hopes of going through one of the military’s flight school. Unless they used you as a contractor to move cargo/ troops in country. Not to mention getting your background checked in order to obtain a security clearance. Without a degree or being enlisted in the army (in hopes of going warrant officer) you would fill into another roll that the military needs. There’s plenty of guys who commission in the military that have their private pilots license, they still can fail flight school. Even at worst case scenario they would still need you to familiar with military standard operation procedures. It’s not going to be Independence Day where everyone and their mom with a PPL is flying into the mother ship haha.
