While in Cambodia I remember being hastily dropped off at a field hospital because my medevac transport was called on a rescue mission.  When I looked inside the hospital tent there were three or four people standing in the doorway.  About thirty feet away was a team of doctors and nurses standing around a table operating on a wounded GI.  The scene was illuminated by a single light bulb hanging over them.  It was the only illumination in the tent.  As I was about to take a picture of this MASH scene one of the people at the operating table told us to leave.  I didn’t take the picture.
