If you look carefully, you can see the soldier. Just look at the crazy guy with the red shirt’s gun arm, and you can see a bit of his head, and you can see his shoulder in the little triangle between Red’s arm and his body.

As for how clean his shirt is, for the answer to that you have to look to his other hand. The gesture he is making is a common African hand gesture that means, roughly translated, “No, I did not just steal this shirt from your store. How dare you, sir. I quite resent this affront to my good name. You are lucky that I am late to the opera, otherwise I would challenge you to pistols at dawn.”
