...namely, there's quite a few cavalry units whose model use some kind of saddle (usually the "Celtic" four-horned one) - but the Celtic (Gallic, Galatian...) ones aren't among them. While I understand the "horned" saddle only came to common use around a century after the EB starting date, as far as I understand there's no "reform" concerning the matter in the game and it does seem somewhat peculiar that the Celtic cavalry is so bereft of probably their single most famous piece of equestrian gear.

An unenlightened soul is puzzled.
