Out of print. DC war comics mixed in a bit of Mission Impossible with the Unknown Soldier. Great stuff!
From the publisher:
Assuming a wide variety of disguises to battle the Nazis in World War II, the Unknown Soldier plunges deep behind enemy lines in this massive SHOWCASE edition, collecting stories that have not been reprinted since they were first published in the 1970s.
The Unknown Soldier stories from STAR SPANGLED WAR STORIES #189-204 and UNKNOWN SOLDIER #205-226 (1975-1979).
