A former soldier has lost his bid for a military disability pension after he failed to convince a tribunal that his stories of wartime daring and adventure were true.

Tales told by Norman Olsen to support his claim for post-traumatic stress disorder included casting himself in a role befitting kung-fu action hero Bruce Lee, taking on a gang of 12 Vietnamese thugs in a Hong Kong bar brawl in the early 1970s.

Australia's Quickflix isn't going down without at fight, striking a deal with a Chinese movie studio.

The Administrative Appeals Tribunal was told how the digger single-handedly battled the gang who were armed with spiked batons and acted like "crazed lunatics ... screaming and yelling" and left just two of the men standing before he escaped.

Other yarns spun by Mr Olsen to the tribunal featured hand-to-hand combat against a Vietnamese guerrilla he found hiding behind a rock, and enduring anti-aircraft fire while flying over the battlefields. They were also taken with a grain of salt by the AAT.
