Gung Ho! dramatically tells the story of the Second Marine Raider Battalion, the group formed six weeks after the attack on Pearl Harbor. The battalion’s purpose was to raid Japanese-held islands and claim them for the United States. Led by Colonel Thorwald, the men endure grueling combat training in preparation for their first mission: to annihilate the much larger and firmly entrenched Japanese garrison on Makin Island. Intense battle sequences highlight this exciting morale booster of a movie.
