DOUR DUTY

The Iron Warriors unflinchingly face their forlorn fate.
Use this Stratagem in your opponent Shooting
phase or your Charge phase, when an Iron
Warriors unit from your army is chosen as the
target for an attack. Until the end of that phase,
when resolving an attack made with a ranged
weapon against that unit, worsen the Armour
Penetration characteristic of that weapon by 1
for that attack (e.g. AP -1 becomes AP 0).
