I’m late to the party… but I was also Security Forces (~9.5yrs), hired at 38yrs old, and just finished MQT. I had an Art 15 when I was enlisted that I had to explain and some units didn’t want to bother. You just need 1 unit to take a chance and say yes. Everyone has a past – just be up front and honest with each unit you apply for and cast a wide net. Let them know what exactly happened and what you have done since then (things that you have done to improve your unit, education, volunteer, etc). You want to show that you are a worthy investment that will deliver not just a pilot but an impactful officer. Also – if this is something you really want, don’t give up. Some units need to see proof that you really want it (by coming back one, two, or three times) before they give you a shot.
Good luck man!
