And how can I change it? In the base game, if you have an army of 5 infantry, 1 hussar/dragoon, 3 arty, and 1 engineer, the sprite will be the arty one (might not be the best composition, but one suggested early game one I've read works well). In HFM, the same army will use the infantry sprite. What file governs the sprite displayed? I'd like to modify the vanilla file to use the infantry model with this or a similar composition, like in HFM.

Why? Simply personal preference. A friend is learning the game and when we play co-op in the base game (with expansions), I want to look at the infantry models and not the floating arty/guard/plane symbol.

I appreciate any insight you may offer!
