Mercenaries

I am about 5 minutes into the movie and very disappointed... First of all you have a Full Bird Col. wearing the uniform all wrong. Then people calling him Colonal... You don't call them by their rank.. Sir... Ma'am.. Then went even further with the Major wearing his head gear inside, and then someone calling a soldier they worked with private. So aside from everyone being all jacked up.. and people getting called by rank this movies script is lacking too. The president is under attack and doesn't realize until they get to his house?? Then they say they have to leave quickly but get caught at the top of their stairs waiting... Who does that? This isn't one of them scary movie plots where the girl runs up the stairs instead of out the door. there is my ten lines.
