Sergeant Silverback

Sergeant Silverback is the no-nonsense SPD Drill Sergeant based on the hostile training planet of Zentor.

When tension among the Rangers reached boiling point, Cruger sent the Rangers to Silverback to be re-trained, as their fighting was compromising the integrity of the team. At first, the training did not go very well, but the Rangers eventually choose to fight together, when faced with the prospect of going their own seperate ways.
