Special Forces Surface Swimming Training Manual TC 31-20-4 1970s

Special Forces Surface Swimming Training Manual TC 31-20-4, likely from the 1970s based on the uniform and design. This 63-page military training circular covers infiltration, exfiltration, operational techniques in unconventional warfare, equipment maintenance, and physical conditioning for military swimming operations. Includes appendices on submarine operations and glossary terms. The manual is in good condition with minor scuffs on the corners.

This is a rare and valuable Cold War-era military reference used by the U.S. Army Special Forces (Green Berets) for combat swimmer training. These manuals were issued in limited numbers and are now highly sought after by military collectors, historians, and tactical training enthusiasts.
