Navy Corpsmen attached to Marine Forces Reserve stationed at Marine Corp Support Facility, New Orleans and Command Master Chief Marine Forces Reserve and Marine Forces North Ryan N. Strack pose for a photo to commemorate the culmination of the Tactical Combat Casualty Care course at Marine Corps Support Facility New Orleans, Nov. 20, 2019. TCCC has been the most effective way to reduce casualties from injuries on the battlefield since 1996 due to its ability to address immediate threats to life and decrease the amount of time before surgical intervention can occur.
