For a quick summary, the ICO is a international anti-terrorist organization funded and organized by the UN. Their job is to handle the threats to big or too slow for standard bureaucracy to get to in time. Ranging from wet work to bodyguarding, or spy work to fighting on the frontlines, the ICO covers it all. Being a part of the UN means that operatives can be from just about anywhere in the world, ranging from military veterans from Brazil, to a SWAT officer in America. Teams aren't defined by there borders and backgrounds, but rather by how effectively they can work together. If you're interested in a tactical military campaign, or even just a game with fairly realistic gunfights, feel free to comment below. I'll do my best to answer any questions about the campaign and the system.
