Drill

Drill is a melee weapon special rule.

When a model attacks with this weapon, this weapon's Att value equals that model's modified Resolve.

After rolling attacks with this weapon, if at least one attack was successful, reroll failed attack dice with this weapon. Repeat this process only while each reroll batch produces at least one additional successful attack.

Drill uses normal melee attack resolution, damage, allocation, and removal timing unless another rule explicitly states otherwise.
