SPOILER: Description of a combat scene.
There are many reviews of BEACHHEAD so I won't post one. It's fairly entertaining if you are into war movies and even if BEACHHEAD is fairly straightforward along a well-used formula.
The best scene in the movie will interest those involved with the Asian martial arts. Late in the movie, the intrepid, old-timer Marine sergeant stays behind to ensnare the relentless Japanese commando sniper, who looks like an Asian version of Rambo, shirtless, clad only in shorts, carrying an Arisaka rifle with sniper scope, and a belt with minimal supplies and a knife.
The cunning Marine sergeant pretends to be shot by the Japanese sniper and plays dead, intending to knife the unsuspecting sniper as he approaches to inspect his latest target. The ploy works, almost. The sergeant had no idea the sniper would be quick on his feet and naturally well-versed in hand-to-hand combat. The next plays out best as the two men grapple in deadly combatives. In fact, the Japanese seems to have the initial edge. He successfully employs two jujutsu/judo throws on the Marine sergeant, who is not injured, although in real life he would have been, and gets back on his feet. He blocks an 'atemi' knife/sword hand blow (edge of the hand) from the sniper which could have injured or killed him. The Marine sergeant doesn't appear to know any official hand-to-hand combat training but uses his own strength, born of desperation, and simple street fighting and grappling to eventually overcome the Japanese sniper. It was curious because the film clearly showed the Japanese sniper having superior hand-to-hand combat training.
It will be more ironic to know that much of Western military hand-to-hand combat during WW2 and ever since then is based on Japanese jujutsu and combat judo. At the end of the 19th century and into the first two decades of the 20th century, Japan actively exported judo and jujutsu to the West as a demonstration of Japanese culture. Unlike the Chinese who jealously guarded kung fu (wu shu) knowledge from foreigners, the Japanese enthusiastically showed the majority of their hand-to-hand combat arts to foreigners, all except for closely guarded family-only taught advanced secrets of jujutsu ryu. Old books from this time period show the Japanese demonstrating jujutsu and judo with Westerners. Combat jujutsu and combat judo formed the core discipline of the Allied nations' military hand-to-hand combatives. It came about not quite directly. A British detective in Shanghai, Fairbairn, developed his own hand-to-hand combatives for the Shanghai police force, known as, DEFENDU, which he based upon his own extensive study of Japanese jujutsu, Western boxing and wrestling moves. At the start of World War 2, Fairbairn returned to England and helped organize the hand-to-hand combat regimen to the British Commandos. The Americans sent instructors to England to learn this style of deadly hand-to-hand combat. Thus the Japanese of WW2 found themselves fighting American, British, and Australian soldiers with jujutsu-influenced combat training. This was irony at its finest.
Many nations including the U.S. teach advanced hand-to-hand combat training that have its roots in WW2. Investigate those roots and all of it leads back to Japanese jujutsu and combat judo. There exists today on Amazon, copies of a 1944 book co-authored by an American man and a Japanese man, both black belts in judo. Since the year 1944 was the height of WW2, the authors oriented the book towards practical self-defense. Interesting, in contrast with post-war judo and its near total emphasis on sport, the book includes a chapter on 'atemi', blows and strikes with the hands, feet, and even head, against listed targets on a human anatomy diagram. This was actually a significant part of Jigoro Kano's early years on his newly-found judo. But time went by, the teaching of atemi became restricted to the black belt ranks and remains so today. The extensive depiction of atemi in that 1944 book would be clearly prohibited under Kodokan Judo today.
