Hey

I was bought the Battle of Calth box set this Christmas by my fiancée and have decided to create a space marine army using the forge world carcharadon chapter tactics . For those that aren't sure of what they are - All models with this tactic have the fear special rule , tactical marines can exchange bolter/pistol with a close combat weapon or buy one for 1 Point per model and models with this tactic gain the rage special rule once they have destroyed a unit in combat or forced them to fall back.
I was hoping that you lovely people could help me create a fluffy list that can also hold its own against most armies or give me some tips on what space marine units are good and why .
The models that I own at the moment are :
-3 tactical squads
-1 chaplain
-1captain in terminator armour
-1 ironclad dreadnought
-1 contemptor dreadnought
-1 drop pod
-1 assault squad
-1 Terminator squad
I also have a imperial knight
I will be planning on purchasing new units though so if anyone has any suggestions about any others I will be able to buy .
Thanks
Renegade Knight
