Strike Squads frequently form the forefront of a Grey Knights strike force. Equipped with lighter armour than the predominant Terminator Squads, these veterans strike rapidly and surely, and are capable to slip through gaps in the enemy line. At the onset of battle, a Grey Knights commander will always assign one or more Strike Squads with the capture of critical areas and key objectives, deploying by way of fixed teleporter to make sure the speedy seizure of remote or inaccessible locations. These Squads are indispensable – without their reconnaissance and preparation, the Terminator Squads would be a hammer swung blindly in the darkness.
