Frogman!

Petty Officer Clive Gellatly was a former boxer who had been in the Royal Australian Navy for about ten years. But he was champing at the bit for more athletic duty. So when a request came through to join a suicide squad of frogmen, he was quick to sign up. He was taken to a remote oceanside base where he trained with another four men for several months …and along the way the five of them coalesced into a strong, capable fighting unit. Then came their first big mission—to destroy a powerful radar station smack in the middle of a Japanese-held island!
