well ill go next
HQ
Space Marine Master
Pros
Can infiltrate, furious charge, or tank hunters. just give this man a power weapon and watch him get up to 5 attacks that dont allow armour saves. heck this man alone with his I5 could wipe out a unit of terminators on the charge.
use him with tactical squad with terminators honour and i doubt anything could effectively fight back with that many attacks
Cons
against a powersword he has no defense, no free inv save, can get very expensive.
