I was having this discussion with a friend of mine. I stated that a personality created from Unexpected Reinforcements could destroy a bowed unit via Greater Sacrifice because the Unit's force is zero for purposes of determining force, but he disagreed. Will Greater Sacrifice destroy a bowed unit if my unbowed samurai has one, or even zero force?
Greater Sacrifice Text: Text Battle: Destroy one of your target unbowed Samurai Personalities: Destroy a target unit opposing him with total Force less than or equal to your Samurai's total unit Force, plus his Personal Honor if your Family Honor is higher than its starting value.

Yes. The total Force of a bowed unit is always zero, unless an effect says otherwise (e.g. Koutetsu Shinri). As a consequence, it is always less than or equal to the performing Samurai's unit's total Force.
