198th Regional Support Group

The 198th Regional Support Group recently completed crew-served weapons qualification at Florence Military Reservation.
By training on the M249 SAW, the M240B machine gun and M2A1 .50-caliber machine gun, these soldiers ensure the Arizona Army National Guard remains a combat-proven, agile, and lethal force. This operational experience is a critical part of our commitment to maintaining a high standard of readiness for both domestic and overseas missions.
continues to provide a cost-effective combat capacity dedicated to defending Arizona and the nation.

We are proud to announce the promotion of three of our soldiers today. Please join us in congratulating Pfc. Schad Natay, Maj. Jake Crocco and Lt. Col. Cullen Metzler on their new ranks!

January 11, 2026 we honored the career of U.S. Army Lt. Col. Robert M. Thorlin as he retired from the Arizona Army National Guard. A military retirement isn't just a milestone for the individual, but for the family that supported them through every drill and deployment. Congratulations on a stellar career and a bright future ahead.

Please join us in congratulating retired U.S. Army Col. Margaret “Meg” Bielenberg on her retirement after 28 years of honorable military service.
