Most jungle firefights are fought over short range and are over in a few minutes. Vision is limited and snap shots at targets are the order of the day.
Australian Army Corporal Jerry Warner was caught up in one such skirmish. With night falling and his life in jeopardy, he blazed away, knocking down attacker after attacker. Then he was blown unconscious by a mortar blast.
He survived but that night continued to haunt him - and he couldn't work out why!
