I only know the most recent story. 

SOLDIER kept the peace between humans and vampires. Anybody trying to start a war or kill the other race was dealt with. With vampires, it usually meant they were put to death or destroyed, because no prison can hold them. They have a militaristic structure and leadership, but they are obviously broken up into groups, etc. right now. Ex-SOLDEIR members would typically be human, but there may still be vampires that work for them, either to establish peace or save humanity. They are well trained, strong, skilled.... sharp shooters, strategists, chemical weapons specialists, pilots, ... um, ninjas... stuff like that. 

Kilo Point was a city in Tennessee. That's where Magnus led his army of vampires to attack. They caused mayhem, brought SOLDIER out to deal with them, and the situation just careened out of hand. In the end, Magnus couldn't be stopped, Kilo Point was leveled, there was a crater left in the woods where a missile barrage landed. Magnus took out all of SOLDIER's guys... took their equipment, and continueed taking over city after... or something like that.

I was personally stuck in a jar for the latter half. *glares at Martin*
