To continue that train of thought.....When I was about 10 years old I stayed up late unbeknownst to my family and watched a war film and the images stuck in my mind ever since, I can't remember the name of the film. I'd like to see it again with adult eyes to see if it was a decent film. The hero climbs into an enemy fox hole where the machine gunner lay dead, took the mg and shot all the other machine gun fox hole emplacements up. Then as the enemy tanks and troops marched forward, he jumped up onto a burning tank and used the top mounted machine gun to mow down all the enemy, while the flames got bigger and bigger. I just remember the purple flames and the machine gun (i think it could have been a black and white film that had been coloured afterwards?) ring any bells?
