Windtalkers

Just saw Jon Woo's WindTalkers, about the Navajo Code Talkers during World War II. The U.S. Navy employed the Navajo language in battlefield communications. The complexity of the language proved extremely frustrating to the Japanese (who were quite skilled in cryptology), and the Navajo code remained unbroken.

The Code Talkers -- between 375-420 in all -- were part of every major Marine assault in the Pacific. Some say that the U.S. might never have won the war in the Pacific without them. "Windtalkers" has the look and feel of a traditional World War II action movie. Personally I wished they had focused more on the code itself and less on hand-to-hand combat, but all in all it was a fitting tribute. Here's another page I came across by the son of a CodeTalker with a lot of background information.
