Raider Capacity

I see a lot of people making lists with units larger than 10, and taking a raider as a transport for that unit. Now I understand the raider can be taken as a dedicated transport, and that units can be taken larger than 10, but where in the rules does the capacity of the raider increase? Its not FAQ'ed or errata'ed. As far as I can tell, although one may take a raider as a dedicated transport for a unit larger than 10, however, the capacity is still 10 models. I'm sorry if this was answered elsewhere, I could not find a topic on it. I appreciate the clarification, thanks.

The Raider's capacity is, indeed, 10 models. The lists in question are either people making a mistake or people not intending to put the squads in the Raider. I don't see many lists doing either besides the occasional new player who presumes we're like Marines.

The capacity doesn't increase, it just means the unit has a dedicated transport.

The unit wouldn't be able to embark inside the transport thus it would have to start separate from said unit. However, because it is a dedicated transport it does not take up a force org slot. Thuss, there is still some an advantage to taking one.

I don't ever do this (take more models than can fit inside) nor do I have the rule book in front of me so correct me if I'm wrong fellas.

Anyway, hope I answered your question.

edit- thor beat me to it

I would never do it with Dark Eldar, but my CSM does it all the time. When I want to run a large mob of marines I will always buy a Rhino for them, for the cheap and fast Objective Secured option.
