Freedom Force

When Mystique determined it was too dangerous for her Brotherhood of Evil Mutants to remain at large during the growing anti-mutant sentiment in America, she approached Val Cooper of the CSA and offered the services of her people as government agents. As Freedom Force, the Brotherhood were put on extended parole, working off their debt to society as agents of the US government. The deal was conditioned on Freedom Force remaining in the boundaries of the law -- one illegal act by any member, and all members would be thrown back in jail. Freedom Force continued on past Mystique's apparent death, until a mission overseas in Iraq left the remaining members dead, mortally wounded, or captured. They were replaced by the government-sponsored version of X-Factor soon afterwards.
