The Hoodlum Soldier

The Hoodlum Soldier , Heitai Yakuza? is a Japanese film directed by Yasuzo Masumura. The Hoodlum Soldier was the first of a series of nine films that followed two soldiers, Kisaburo Omiya Shintaro Katsu, a former yakuza who has become a soldier, and Arita Takahiro Tamura, an intellectual from a good family who has deliberately failed the officer examination.

The base commander asks him to take charge of Omiya Shintaro Katsu, a soldier who responds poorly to military discipline. Discipline at the camp is imposed through beatings, with noncommissioned officers being able to freely punch and kick the lower ranks for infractions and failings. Former yakuza member Omiya proves to be very much tougher than the other soldiers and often responds to the beatings with violence. Arita tries to obtain fair treatment for him, for example refusing to let him be beaten with a wooden bar. Omiya forces his way into a brothel for officers and befriends a prostitute Keiko Awaji there.Arita becomes friends with Omiya and helps him survive a training forced march, in which Omiyas feet become covered with sores. After another infraction, Arita is ordered to beat Omiya. He hits him once with a shinai, but cannot bring himself to hit Omiya more. To save Arita from being disciplined, Omiya hits himself in the face with bricks, drawing blood. After a soldier is beaten by the catering soldiers, and then escapes from the camp and commits suicide, Omiya picks a fight with the catering soldiers. They trick him by pretending to befriend him then attack him in a secluded part of the camp. Arita rescues Omiya. ........
