The 433rd Training Squadron's mission is to recruit, train and maintain a cadre of Military Training Instructors who augment the Air Education and Training Command. They support the 737th Training Group and seven basic training squadrons in preparing approximately 37,000 enlisted trainees each year for the USAF military service. During peacetime, the squadron trains Reserve MTIs for wartime surge requirements.
The 433rd TRS is unique to the Air Force Reserve Command as it is the only unit of Reserve Basic Military Training Instructors. The BMTIs of the Alamo Wing are total force partners with the 37th Training Wing in providing for the next generation of Airmen.
