'And They Shall Know No Fear'
Space Marines automatically regroup as they fall back, even if the squad is reduced to less than 50% by casualties. If the enemy advance into them the Space Marines are not destroyed and the advancement of the enemy unit is treated as a new assault (enemy striking: +1A the following turn) in the same way as a sweeping advance. If the enemy do not advance into them the Space Marines are free to move, shoot, and assault normally in their following turn.
Drop Pods
At the start of a battle where you can use the Deep Strike rules, you can declare that your Space Marines are deploying by landing in drop pods from orbiting spacecraft. Models doing this deploy using the Deep Strike rules in the Warhammer 40,000 rulebook.
Only the following can deploy from drop pods. No other models in the army can be used in this mission (they stay onboard ship).
Laser Technology
As described before when the Iron Claws were isolated the ability to produce and maintain Laser weapons. All the resources were used to build and maintain both the Gigantic Planetary Defense Lasers and Heavy-Duty shipboarn Magnetic Guass Cannons.
Scouts
Iron Claw Scouts are veterans that have volunteered for this duty, they are Immune to Psychology and are highly dedicated to their task.
HQ
Iron Claws may always take one more HQ choice than the force selection chart allows.
Allies
The Iron Claws may ally as normal with Space Marines, Imperial Guard, Heroes of the Imperium, Squats, Eldar and Callarans.
