Syndicate (The X-Files) - Men in Black

The Men in Black refers, unofficially, to a group of enforcers employed by the Syndicate to take care of the dirty work of the conspiracy. Most of them were ex-military, highly trained and loyal hitmen, who worked, as a front, in government agencies such as the Federal Bureau of Investigation, Department of Defense, and the National Security Agency.

The Men in Black are analogous to the Alien Bounty Hunters employed by the Colonists. The Men in Black were, however, not as reliable as the bounty hunters and though sometimes they were used initially it took the more capable Alien Bounty Hunters to complete difficult tasks. The Syndicate would use the bounty hunters only when absolutely necessary because of an increased risk of exposure.
