Attacks with this special rule may re-roll failed Armour Penetration rolls against Vehicles and Buildings (both with Shooting Attacks and in close combat) and re-roll Glancing Hits, in an attempt to instead get a Penetrating Hit, but the second result must be kept.
Weapons with the Master-crafted special rule allow the bearer to re-roll one failed roll To Hit per turn with that weapon.
