The combat engineers of the First Marine Division, 9th Engineer Battalion, risked their lives daily in Vietnam as they cleared the roads of mines, repaired and paved the famous "Highway 1," disarmed booby traps, built bridges and culverts, and destroyed enemy bunkers and tunnels. Despite their sacrifices and pain, the combat engineers in Vietnam have heretofore largely been ignored. This is the first oral (or other) history of the 9th Engineers, the only Marine battalion formed specifically to go to Vietnam. More than 35 men of the 9th talk about why they joined the Marines and their experiences in basic training. They speak candidly and compellingly about their five years (1966 to 1970) in country. The soldiers also discuss what it was like to come home and get on with their lives.
