|This article is about a/an ally in Power Rangers S.P.D.|
Sergeant Silverback is the S.P.D. drill sergeant who teaches B-Squad to work together. He is very bossy and cynical and speaks like a stereotypical military officer. He also looks like a cross between a caveman and an orangutan. Silverback returned in 'Endings Part 2' to aid the Rangers in facing the Troobian forces. He also brought his own R.I.C. with him, and another S.W.A.T. truck to assist in the battle.
Sergeant Silverback was voiced by John Tui.
