Sigma Team

Sigma Team was an elite team of the Special Activities Division branch of the CIA. Lead by Russell Adler, Sigma Team's tasks involved hunting down and eliminate members of the Soviet spy ring known only asPerseus. To eliminate It's leader, a Soviet military leader codenamed Perseus. Sigma Team was commissioned by President Ronald Reagan to prevent international catastrophe at the hands of the Soviet spy ring. Sigma Team comprised of Russell Adler, Bell, Alex Mason, Frank Woods, and James Hudson.

Together, Sigma Team served a three year tour in Europe employing clandestine methods in their manhunt for Perseus. Sigma Team even infiltrated the highest levels of the KGB, becoming a legend among members of the Special Activities Division.

In 1984, Sigma Team assaulted Perseus' headquarters in an attempt to prevent them from transmitting nuclear launch codes to Soviet missile bases all throughout Eastern Europe and enacting nuclear war. Sigma Team was then betrayed by Bell, who revealed his true allegiance to Perseus. Bell and his agents of Perseus ambushed Sigma Team, slaughtering the members of Sigma Team.

Bell would reunite with Perseus and transmit the launch codes to the nuclear missile bases. However, unknown to Bell, agents of XOF would infiltrate and shut off the Duga Radar. Rendering their plan useless.

Upon Bell and Perseus' exit from the battlefield, XOF agents recovered the bodies of the team, and rushed them to a hospital in which they were brought back to life. Sigma Team remains a legend within the CIA to this day. However, believed to be killed, the members of the team still operate in foreign nations. Performing clandestine operations on behest of the CIA.

Sigma Team would later receive additional funding and become It's own paramilitary force, tasked with hunting down targets for the CIA. Sigma Team would later hunt down and kill Perseus in an airbase in Belarus in 1988, and using his information, traveled to Kashmir to hunt down and kill Alexei Bhukarov.
