Older Aragorn model

[cpt_safety]

I have an Aragorn model mounted from Two Towers (scenes/chapters fighting warg riders - riding out from Helm's Deep). What’s the best way to add this model to a Riders of Rohan army. I don’t do tournaments, I just want to be able to group he and Theoden with a group of riders and calculate points.

I tried to just do a Free Peoples group, but Aragorn/Strider doesn’t have the option of a horse.

Thanks,
Bill
