The United Baltic States is a direct successor to the former governments of the region, whose previous leaders were rescued and protected by Lambda. The region is regarded sometimes as one of the most dangerous in Europe, with it's waters infected with leech and the majority of it's coastline under antlion occupation. The small nation has a strong industry though, with the former Combine controlled population centre of Tallinn (City 84) relatively untouched by the revolution and completely stable due to the experience of the men and women in power. It provides ammunition to the Lambda, resulting in a strong political and trade alliance.

The Lambda stood by the small nation during it's time of turmoil, as did the States to Lambda.

The small nations' military is mostly made up of former Conscripts who put down their flags to join the revolution - because of this, they have relatively easy access to pre-War Russian and American military vehicles.
