Some rules allow you to re-roll a dice roll, which means you get to roll some or all of the dice again. Similarly, if, after all the cumulative modifiers to a hit roll have been calculated, the total modifier would be +2 or better, it is changed to be +1. This means that if, after all the cumulative modifiers to a hit roll have been calculated, the total modifier would be -2 or worse, it is changed to be -1. A hit roll can never be modified by more than -1 or +1.

An unmodified hit roll of 6 always scores a hit, and an unmodified hit roll of 1 always fails.

If an attack is made with a weapon that has an ability that says it ‘automatically hits the target’, no hit roll is made – that attack simply scores one hit on the target unit. If not, the attack fails and the attack sequence ends. If the result of the hit roll is equal to or greater than the attacking model’s Ballistic Skill (BS) characteristic (if the attack is being made with a ranged weapon) or its Weapon Skill (WS) characteristic (if the attack is being made with a melee weapon), then that attack scores one hit against the target unit. When a model makes an attack, make one hit roll for that attack by rolling one D6. In this case it can do so even if other friendly units are within Engagement Range of the same enemy unit, and it can do so with any ranged weapon it is equipped with (excluding weapons with the Blast ability).Īfter a unit has fired Overwatch, it must complete the Set Overwatch action again before it can fire Overwatch again. A unit cannot fire Overwatch while enemy units are within Engagement Range of it unless it is firing Overwatch at an enemy unit that has just finished making a charge move within Engagement Range of it. Overwatch is resolved like a normal shooting attack except that models can only target the enemy unit that has just finished moving, and an unmodified hit roll of 6 is always required for a successful hit roll, irrespective of the firing model’s Ballistic Skill or any modifiers. Each time an enemy unit is set up on the battlefield or ends a Normal Move, an Advance move, a Fall Back move, a charge move, or opens a Hatchway, units from your army that have Set Overwatch can fire Overwatch at that enemy unit. If completed, until the end of your opponent’s next turn, that unit is said to have Set Overwatch. The action is completed at the end of your turn.

One or more units from your army can start to perform this action at the end of the Move Units step of your Movement phase.
