Seabees at work under combat conditions. We were trying to get as fast as possible a place that was safe and that was to dig bunkers for protection . The work was hard , dirty , tiring, and working in mud and rain at the same time. Trouble was while digging and building bunkers you were exposed to the enemy who just did not want you there in the first place so the odds of completing the work safely without casualties was not a sure thing. You worked  exposed daily papa 7under constant fire be it small arms or mortars . Even with the bunkers completed you still had to come out sooner or later for whatever reason . You were still exposed and fair picking for charlie . It was a day to day gamble would you be the casualty for that day . I guess the hard work made you seem oblivious to your surroundings, and what was happening around you . No time to think  . Picture was taken at Ben Luc  while we were building under ground bunkers .
