Randomized Weapons/Helmets? Thread - GEM 2 Editor Fan club

Hi all, I'm a bit new to modding, and I have a question.

A couple years ago, I remember an AS2 mod called "Panzer Mod" was released. I remember noticing that in the editor, whenever you would spawn a Russian Partisan, their skin/weapon/headgear would be constantly randomized. I tried looking at the breed files from the mod's page on this website, but there was nothing out of the ordinary.

So, I was just wondering if anybody on this page would know how to go about doing this. I'm trying to make a mod for Men of War: Vietnam, and it would be cool for soldiers to spawn with different types of hats and helmets (and weapons, especially for the Viet Cong).

Any help would be greatly appreciated!
