40th Support Detachment - California State Guard

03/14/2026

In October 2025, Soldiers from the 40th Support Detachment came together for a full-unit muster and physical training session. Events like these are more than just PT, they strengthen unit cohesion, build trust across sections, and reinforce the teamwork that keeps our formation strong.

Bringing the entire detachment together reminds us that readiness starts with connected teams and shared standards. Proud of the Soldiers who showed up, put in the work, and continue to represent the strength and professionalism of the 40th Support Detachment. 💪🇺🇸
