Editing Warhammer 40,000/9th Edition Tactics (section)

====Allocating Wounds====

After you have rolled to wound, the attack gets allocated to a model in the target unit.  Unlike in 8th edition, not only must this attack be allocated to any already wounded models, it must be allocated to whichever model in the unit has already had attacks allocated to it this phase, regardless if it actually lost any wounds or not.  Bear this in mind when it comes to weapons with different AP or damage stats.
