Skyclaw
In the Space Corgis, the reckless troublemakers from the Blood Claw packs are reassigned to the Skyclaw Assault Packs as a "reward" for their stubbornness and naivete, and are given jump packs to aid their eagerness to charge straight into the line of battle. As you may already guessed, these are the Wolves equivalent of Assault Marines.
The experienced elders look down on the Skyclaws as dishonorable, since fighting on foot was good enough for their Primarch and so it is good enough for them. This disapproval among the experienced Space Wolves only drives the Skyclaws to perform risky acts of valour and heroism. While many will surely perish in attempting to achieve such a feat to be worthy in the elders' eyes, some will inevitably succeed in accomplishing the impossible.
Skyclaw packs are very competitive and always try to out-do the other in battle and in drinking competitions where some have been known to steal Thunderhawks and race towards the enemy commander, delivering his head to the Wolf Lord on a silver platter he would surely win against his rival packs. Skyclaws are rarely disciplined for their reckless behaviour and only in extreme circumstances will a Skyclaw be given a punishment to fit the crime.
