Question about British Units ingame during the Waterloo battle

I was just wondering if the units you control on the British side of Waterloo were recruitable in campaign. Any help would be apreciated.

I do believe that many of them are in fact Waterloo battle only(Brunswickers come to mind as well as some of the KGL units)but I do as well believe that there are some mods out there that change this.look in the gameplay tweaks /Units packs section of the released mods

Most of them are although Brunswick line are not. Oh, and the Earl of Essex. Through modding you can edit it so you can play as them, though,=.

Yes they are recruitable in campaign with modifications. I also need historical Generals to campaign, but I will find it out how to do it.
