I had an idea this morning of a new Space Marine chapter. On the tabletop they would play just like any other Space Marine army, its just fluff Im playing with here.
Chapter is called the Numerators, and they believe the entire galaxy can be broken down and controlled with the right sequence of numbers. Every fight they get into, they calculate odds and search for the hidden meanings behind every possible number encountered, from the number of orks killed, to the number of bullets that hit their tanks, to the amount of ammunition spent by the task force.
One of their defining features is their lack of a real chapter badge. Instead, every Space Marine has a unique four digit number assigned to them, that is stenciled onto their shoulder armor, and they keep that number for their entire life. When the marine dies, the number is recycled, unless it belonged to the Chapter Master, then that number is retired. Chapter banners bear the Chapter Number of 862.
The Chapter is laid out in a very different format then Codex chapters, and even non-Codex. They have all the usual ranks, 10 Captains each with an assigned Command Squad, and assorted chaplains, librarians, techmarines and what have you, but there are no companies. When the portents are in favor of combat, the Captain in command will select the troops he believes will be most useful for the situation. Despite not having companies, each Space Marine belongs to one of then "Lists", each List being tended to by a particular Chaplain and Apothecary. Each squad will assume the needed role and equipment right before combat, as the randomized numbers dictate.
If I get around to working on these guys, I plan to do them all magnitized. Ill prolly also not use the tac badges like I put up there... though Im not exactly sure what I would put. If anyone else wants to have at them, go for it! :)
