Friendly hand to hand combat between opposing Vietnamese soldiers

The fierce mixed fight hand to hand combat martial art. But friendly. Punching and Kicking. A North Vietnamese male soldier with no helmet or hat in traditional green uniform attire that engages in a friendly hand-to-hand combat with a South Vietnamese female soldier of the Republic of Vietnam, who wears a simple olive green uniform and has medium hair, her eyes locked in a playful challenge, both figures set amidst the lush greenery of a Vietnamese jungle, circa 1965.
