I've been thinking a lot about how many marines a Space Marine chapter actually has.
There's a lot of guys that aren't included in the "1000 marine" limit. Each company has a command squad and standard bearers/ancients, and then there's the specialist branches of the Apothecarion, Armory, Librarius, and Recclusiam, and then the Honor Guard, a bunch of officers, and all sorts of other things.
Each chapter probably has between a couple hundred and a few hundred marines in addition to the ten companies, ten squads per company, ten marines per squad.
