SNAFU: Everyone Has Their Demons

The South Pacific - 1942

When most of Matt Turner's fighter squadron is destroyed by Japanese Zeroes with demonic protection, he expects his after-action report to land him in the loony bin. Instead, he finds himself recruited by a shadowy government agency to test a supernatural countermeasure before the Japanese strike a deathblow against the U.S. Navy and win the war in the Pacific theater.
