Echidna Security Team

The Echidna Security Team or "E.S.T." was the primary defense and police force of Echidnaopolis. The leader of the E.S.T. held the rank of Constable, who also acted as a liason to the Brotherhood of Guardians. While the Brotherhood had often held off the Dark Legion from taking over the city, during Knuckles the Echidna's tenor as Guardian it was the E.S.T. who fended off against the Dark Legion's invasion with assistance from the Dingoes. Following the fall of Angel Island to the forces of the Eggman Empire and the Dingo Regime under Kage Von Stryker, the E.S.T. ceased to exist. (StH: #138, KtE: #8, #9)
