G.I. Samurai

On their way to a manoeuver, a wildly mixed group of Japanese soldiers with a tank, an Armoured personnel carrier, a patrol boat and a helicopter suddenly find themselves stranded 400 years in the past and under attack by samurai forces. Their designated leader, Lieutenant Yoshiaki Iba (Sonny Chiba), befriends and joins forces with Uesugi Kenshin, the war leader of lord Koizumi. Seeing the stranded soldiers' war machinery in action, Kagetora persuades Iba to aid him in his struggle for supremacy in Japan.
