I don't know if they are. Are the people who walk around with the flag at some Demo or GOP party meeting real soldiers? And, if they are... how to they end up doing the ballet in front of freaky politicians?
Is it like some secretary calls the nearest army base and says: "can you guys send us 4 to six warm bodies with some kind of weapons and colored uniforms to walk around the convention halls while the sarge barks orders at them? And then the man in charge at the base does the paperwork and sends them over in a military truck? And, after they're done they get a cold sandwich and then, back into the truck and back to the base?
It's so stupid...
I hope they're fake because it's better if they're just professional dancer doing a soldier impersonation.
