1968 U.S. Army FM 57-38 Pathfinder Operations Vietnam Era Field Manual

Original U.S. Army Field Manual FM 57-38, Pathfinder Operations, dated October 1968, with Change No. 1 dated July 2, 1970. This 75-page Vietnam era manual covers Army pathfinder operations, including helicopter landing zones, sling load pickup and drop sites, radio communications, aircraft control, landing site selection, navigation assistance, and related airborne and air assault procedures. Illustrated throughout with diagrams and operational layouts, including CH-47 sling load site arrangements and helicopter landing area procedures. The manual is three-hole punched for binder use and shows normal age, light staining, handling wear, and some discoloration to the cover, but remains complete, readable, and in solid overall condition. A good original Vietnam era reference for collectors of U.S. Army airborne, aviation, helicopter, pathfinder, and air assault material.
