Sharing the last Space Marines (Light Brigade) I've been able to design for Valkyrx Gaming!
These are elite troopers that are fast and agile. Their body armour offers good protection, but is lightweight, and does not inhibit their mobility.
Their role is fast deployment to hold strategic points awaiting the arrival of the more strongly armoured and equipped Heavy Brigade.
They carry a variety of highly destructive weapons even though they leave the heavier artillery to their cousins in the Heavy Brigade.
Their agility and speed can be enhanced by a lightweight ecto skeleton on the legs and arms.
