If you want a team base all out war type of server that uses lots of custom maps, and bot count over 500+ look no further then [SoTu] Special Operations Tactical Unit server. I am the admin and the ip address is 104.192.227.162:22654. Come check us out, but remember, no rambo players on this server, well maintained and respected. Ask for me: [SoTu] FreeZe.

Warning: Our server is for those who are experienced in Insurgency. You will not have a w/k record like you would have on other servers, for frustration and an adrenaline rush are bond to happen here. Most players leave our server because it is just to hard and unforgiving. Just the way [SoTu] likes it. hahaha.

Bot Massacre is also worth checking out, they have four servers
