If this picture could be summed up using a single word, the word would be 'joy.' The man in this picture is Lt. Colonel Robert Stirm, in full military uniform, being greeted by his family. They've been waiting to see him for a long time.
Stirm was captured by Vietnamese forces during the war, and was held for six years. During that time, his young children were growing up without him. Stirm waited a long time for his freedom, and a camera was there to capture this beautiful reunion.
