Every codex these days is getting a supplement book with 'specialty' formations and rules. It'd be nice for the Space Marines codex to have a supplement that includes all the chapters with separate sections for each one. Make it a $60 supplement and I'm in.

It doesn't even have to be huge changes. Just use the 'Gladius Strike Force' as a base, then change one or 2 formations based on chapter with new rules to boot. Also add in a special character or 2 per chapter to get things on par with Ultramarines and Black Templar, just to make others feel less left out. Check out these ideas:


Black Templar

Formation: Crusader Legion (replaces Battle Demi-Company)

1 Captain*
3 Units of Crusader Squads
1 Vanguard Veterans
1 Assault Squad, Bike Squad, or Land Speeder Squad
0-3 Units of Dreadnoughts, Venerable Dreadnoughts, or Ironclad Dreadnoughts

*High Marshal Helbrecht or The Emperor's Champion may replace the captain choice for this formation

Requirements

All Crusader Squads must be lead by a Sword Brother and have at least 1 Neophyte

Special Rules

Fury of the Crusade: Whenever a non-vehicle unit in this formation suffers a wound from a shooting attack, it must take a leadership test as if it had lost 25% casualties. If the unit fails the test, they fall back as normal. If the leadership test is passed, the unit may move d6 inches towards any unit that fired at them. This special move is made at the end of the shooting phase and can only be used once per turn, no matter how many times the unit was shot at. The unit counts as moving during their next turn but may still move and assault normally

Unstopping Assault: If 2 Crusader Legions are taken, all vehicles with a transport capacity taken from the Codex Adeptus Astartes: Space Marines book gain the Assault Vehicle special rule.

Formation: Council of Fury (replaces Librarius Conclave)

3-5 Chaplains*

*One Chaplain may be replaced by Chaplain Grimaldus

Special Rules
