We got an inside look at how Army combat medics are trained at Fort Sam Houston and Camp Bullis in San Antonio, Texas. About 5,000 soldiers graduate every year from the 16-week training program, which teaches soldiers to control bleeding, manage airways, and perform blood transfusions. After 15 weeks of classroom instruction and hands-on training, trainees spend the final eight days treating patients in a simulated combat environment known as the field training exercise. Insider spent five days immersed in the course, where we observed different classes at various stages of training.
