I'm fairly certain that this has been asked before but I've trawled through the search for the past 30 minutes and discovered it will be quicker to ask the experts :
Is there anywhere we can get hold of a list of unit stats for each faction and what buildings are required to train each unit?
Clan Berserk had a very good list for MTW, so I guess it's just a matter of time before someone does one for RTW.

Also, whilst playing and hovering the pointer over some areas on the campaign map, I saw that the text for elephants indicated anyone could train them. They are a resource available to several factions but can they all train elephant units?
Is this the same for several units, or are units all faction specific? I saw Iberian infantry in a Numidian army and I know the Carthaginians can train them, so what's the deal? I can't fins any info anywhere.
