Small squads of sternguard

[Jackelope King]

Sternguard in small units general come into their own at high points-values games (around 2500). At 2500, Pedro really becomes worth it, and small units are the only kind of units in Codex: Space Marines that really benefit from being Stubborn. You tend to be able to lock enemy units in combat and hold them still while you wait for a real beater, like a squad of TH/SS Terminators to roll around and smash face.
