Rolling to Hit

Source: 3rd-A-Palooza (3.5) Rulebook v1.4, p. 20

To determine whether hits are scored roll a D6 for each Attack a model has. The dice roll needed to score a hit on your enemies depends on the relative Weapon Skills (WS) of the attackers and their foes. Compare the WS of the attackers with the WS of the defenders.
