Buz Sawyer by Roy Crane

Roy Crane created the adventure comic strip with Wash Tubbs, and many a superhero owes a debt to Crane’s square-jawed, hard-hitting adventurer Captain Easy. But during World War II, he left the Captain Easy strip to create a more realistic fighting man, a Navy pilot named John Singer Sawyer, who fought in the Pacific Theater from 1943 until V-J Day in 1945, and whose adventures continued under Crane's pen for three more decades.
