Bullets Hitting

kingpin

umm i dont know if everyone has seen THE BEST MOVIE EVER, which is black hawk down. well there is a scene where theres a technical mounted with a 50 cal gun, and when it shoots it makes a huge like spray of dirt going everywhere. i was wondering if some1 could make a sprite like that when a hmg hits the ground, alien or structure it has a huge spray. if this is possible could it be done for all guns but getting bigger gradually as the guns get better.

thx
