As a soldier? well, you shouldn't, and just in case you need additional confirmation... For your trouble you get charged for second-degree impersonation. That's what happened to the genius here that pretended to be a soldier to get upgraded on AA, complete with fatigues and fake dog tags. He freaked out when confronted, saying that he was E5 but wearing SSG insignia and unable to answer where he was stationed. Oh, and he couldn't produce a military ID either. http://www.nypost.com/p/news/local/gi_faux_scams_airline_ARkpJzHfxRxYhf0KOlb3tM I wonder if this was just a nice gesture from an FA to move him to the front or if he actually asked for the upgrade because he was (faux) military.
