I don't think she really knows who is using who here. It seems she was out of it for the whole time her story was being told and there were people saying that maybe the "Rambo" story was not exactly true. She and her family need to go back over all the propaganda from all sides before they start the movie. Now that she is well, she can tell her story but it seems important parts are still missing. It is quite possible that the wreak that caused her legs and back to be broken also damaged her weapon. We'll most likely never know unless she can face the memories and then tell her story and have it told countless times on TV. She did enlist in the Army but not for this kind of parade. The media are the ones who made this a circus.
