Here is the situation: An Eldar Wave Serpent is assaulted from the front and a penetrating hit is scored. Can you use the Serpent Shield to downgrade to glancing hits?
The question we landed on is in the BRB, are 'hit resolved against the vehicle's rear armour' hitting the rear armour or you just using that value and they hit the armour facing you are attacking? This effect vector strike as well.
