Looking for career advice. Continue Guard or go Active?

That's a highly personal question. Most people who join AD later in life realize that it's an actual career with amazing benefits and do very well. Can you see yourself doing almost 20 more years to get a retirement? There's no guarantee you'll keep your MOS, 15P's aren't in great need right now. In your current MOS you might get more out of the AGR because "I think" the NG may have more aviation units than the regular Army. But maybe you'd like to work in a different field instead. There's just too many variables really.

In the end, I suggest you pick whichever gives you the quality of life you're looking for. If you have 13 years in now, you're bare minimum 31 which means you could retire as early as 51, that's a long time to be in the regular Army if you're in an MOS like 15P that's hard to promote in.

Have you considered looking into a federal job that requires membership in the ANG or USAR as a condition of employment? Many technicians do exactly that and go to work every day at their units as civilians. Maybe your unit doesn’t have any of those positions but if you are willing to relocate you might be able to get a position somewhere else. Those aren’t bad gigs, either. They are usually at least GS-11.

Active duty will be a-holes and take a stripe. Consider AGR in the ARNG or USAR. Get on MOBCOP at the unit ( use their VPN to log in and register for tours).
