It been a long time. But I remember my dad telling me about getting there engines shot up and have to make a emergency landing during his first tour of Vietnam. He was a door gunner on a Huey. They had to bring in a platoon to help guard them while they fixed the Huey. Dad said the Vietcong was all around them. My dad did two tours and never really talked about it much and I didn't push him for info.
