Welcome to the Official site of the Unity Security Force (USEC). USEC was opened on 1 April 2002 as a division of the now defunct Unity Virtual Aviation Community. USEC conducts simulated military operations in a role-playing environment for mature players. Memberís achievements and stats are recorded and rewarded to give a complete virtual military career. USECís Land Forces conduct operations on the ArmA 3 platform with an emphasis on realism and challenge, while USECís Air Forces conduct non-combat air operations on Flight Simulator X using FSHost and the VATSIM network. Our doctrine is inspired by real world tactics, but built from the ground up for our virtual platforms.
