If you mean DEVASTATING CHARGE then yes, they do get it, when all three doctrines are active.
DEVASTATING CHARGE
The White Scars favour shock assaults, crashing into the enemy with overwhelming force. They are experts at using this high-speed impact to drive their blades home with devastating force and decapitate their prey.
Whilst the Assault Doctrine is active, when resolving an attack made with a melee weapon by a model with this ability in a unit that made a charge move or performed a Heroic Intervention this turn, add 1 to the Damage characteristic of that weapon for that attack.
