Navy Seabees at work building underground bunkers at new camp Ben Luc Vietnam in 1969. Detail from MCB 10 Papa. Working 6 1/2 days a week  sun up to sun down .During some of the most miserable weather Vietnam had to offer . Deep in mud . and monsoon rain, and the NVA next door waiting for night to attack which was a frequent  occurrence. During the night you were always on alert and hoping you would make it to the next day . There was no sleep . Between the enemy and the rats which were the size of large cats sleep was impossible . You lived in a dream world forgetting the past and living day to day this was now your world .  papa 8
