Some more pictures of the uniforms. The tan uniform that the guy with the handlebar mustche is wearing seems to only be an undershirt for the black uniform.
BTW the games take place in 1909 and these are supposed to be Federal Army troops
the officers are a bit close to the reality but not al the way, one thing to say is that around that time there was many variations as per location, the farther away from mexico city the more relax it was for some commanders , but it was not the case for regular troops, even today you see generals commanding special forces that do not conform to the training of the ones they command as they are a class appart , long hair, small weapons and the privilege of having their chow made special for them and they also eat separated from their troops, so the possibilities of uniforms for this game are almost accurate, the other thing that you can do is look a my photos posted here as there are many examples of the same uniforms.
i hope i was able to help with your question, cheers!
