I have no idea, but Combat Brute doesn't involve breaking your own armor/weapon. (It does have Improved Sunder as a prerequisite.)
Improved Sunder = break own treasure.
Combat Brute = either bull rush then gain bonuses next round (Dungeoncrasher doesn't one round it?), charge and then gain bonuses next round (what charger doesn't one round his target?), or break enemy weapon or shield aka break own treasure which probably has about as much effective HP as said enemy to cleave into that enemy. I don't get it. She'll own you in a better way.
Now, we return to Bob on Meg action.
