Only the most trusted of the Brotherhood Of The Serpent's troopers ever attain the renk of "Crimson Guardian". All of the Crimson Guardians in service rose through the Viper ranks and had to risk their personal safety defending Cobra before they were even concidered for the honor of serving as Cobra's personal bodyguards. Crimson Guardians are the most feared of the Brotherhood's troopers.
