I might be able to offer some advice with my own experience in the Air Guard. For me it has been an overwhelming positive experience and without a doubt I became a registered nurse because of the military. I have always been an Aerospace Medical Technician (Medic) or 4N0 and have been in this position for 12 years. I am currently in the process of commissioning which sounds like that is your plan.
One of my Airmen who is also a 4N works a firefighter for his civilian job and in his experience, the commitment has been tough managing both guard drills, training and other military obligations with his firefighting schedule FYI. He is getting out after serving 6 years.
What are your options for ANG and Reserve bases that you can realistically travel to in your area? Do you know what these bases have for nursing positions and opportunities? Many guard or and reserve units can go up to 110% with their nurses so you may be waiting a while to land a job with these units. For my unit they have been at 110% for nurses for a number years.
For me, I am dead set on CCAT (Reserves) or flight nursing (ANG) because I want the experience and the deployment opportunities that come with these positions. Both of CCAT and flight nursing have bonus attached to them right now. Our nurses at my unit do not deploy because it is not part of my units mission.
I was told that every 2.5 years of civilian nursing experience post BSN can add years in time in grade or allow you to put rank on sooner. I have not been able to find the specific regulation, AFI or DODI that states this so I am waiting to hear back from my recruiter.
Your pay per drill is around 414.00 before taxes per two weekend drill with 0 years in the military as 0-1. Plus your 2 weeks a year or AT days would be around 1400$ before taxes (some states exempt state tax for drills such as my state).
There are many opportunities in the military both financially and clinically. Serve 20 years and get a pension and healthcare was a big plus for me to stay in and do 20 once I hit the 10 year mark.
