Gung Ho!

The United States Marine Corps is seeking volunteers for a hazardous mission and special unit. The Marines are ordered to board two submarines, the USS Nautilus and the USS Argonaut, destined for a commando raid on a Japanese-held island. The film moves rapidly in a documentary style, with stock footage of training narrated by Chet Huntley. Those who make it through the training are sent to Hawaii for further jungle warfare training, where they witness the damage of Pearl Harbor.
