The Scorpion's Bite Automatically shoots before close combat is resolved — in the same way as a Mandiblaster. Work out shooting as normal for a Mandiblaster. If the Scorpion‘s Bite hits, roll 2D6 and pick the highest; if the score is equal to or more than the target‘s Toughness, D3 Wounds are sustained.
Mandiblaster The Mandiblaster automatically shoots before the combat proper is worked out in the exact same way shooting is done. If a hit is scored, roll a D6. If the score is equal to or more than the target's Toughness 1 wound is sustained if their armour save is failed.
