Well, to be honest, I am not a big fan of this "indie" look.i am starting to populate the scenario ..... i am not really good at unit design so i borrowed some images from this fantastic site

the resul is a new skin for panzer corps units in a more india stile see below

I just prefer the good old Panzer Corps units style. Making new infantry units is one of the easier thing compared to making new planes or tanks from scratch. You can use the vanilla units and just change the colour here and there and you have a new looking unit. And
BNC is absolutely right. It is one thing to create a new unit icon, but it is much harder to make appropriate matching animations. So I would also suggest to use existing unit icons as for those you can use the existing unit animations.BiteNibbleChomp wrote:
If I was making this mod, I would just be going for a slight recolouring of the infantry units the game already has. It makes it a lot easier to program the animations that way.

For example our friend Gary Childress made some nice infantry for both sides a while ago:
I would definitely use these, or variations of these as I think they are superb. I know that for example the Nationalists had a sand yellow uniform as well for those Moroccan Regulars and they might had a red hat, but the above icon can be easily recoloured to get the desired result. You can also use these to your idea to have different "levels" of infantry by erasing one or two figures. Just always keep in mind the animations. For the above ones I think the Bridge Engineer animation fits nicely as it only has rifle fire (submachine guns were not very common in the Spanish Civil War if I am right.)
It is also fairly easy to make irregular infantry - you just need to recolour some parts of their uniform to make look like random civilian cloths - just like I did for the partisans in my mod:
