My drill sergeant once said that every soldier in media who isn’t a real soldier will have a fucked up uniform somewhere due to it being illegal to impersonate a military member. The fubar’d uniform is to protect them from stolen valor allegations as there is nothing illegal about wearing a uniform top or pants as long as you’re not trying to pass yourself off as an actual soldier or vet. Putting flags on wrong, missing insignia, stuff like that is intentional in a lot of cases where its actors portraying them instead of actual soldiers. Whether that’s actually true or not, I have no idea, I wasn’t in a habit of questioning drill sergeant at the time.
