I'm not sure myself either. I think there's a Parry move (sounds like the standard block), a kind of Stun move, that leaves the enemy vulnerable to an attack (sounds pretty familiar as well - spamming this one twice in previous AC's, though not Unity, always tripped up the enemy), the basic Punch and probably a Shoot move as well for the revolver.
