Echidna Security Team

Known more simply as the EST, the Echidna Security Team is essentially the police force of the city of Echidnaopolis. Presumably formed some time after the city's founding, it was led in modern times by Constable Remington. It's members served as something of a counter-army to both the Dark Legion and the Dingoes, at least until the latter force formed an alliance with Dr. Robotnik. The EST was presumably disbanded after that, with its members winding up in prison camps.
