Rihanna - Hard feat. Young Jeezy (Video)

A few days ago I was doing some reading and found a few comments by readers writing about Rihanna's change up over the past 5 years.  If you remember when Rihanna first started she came in with some party music, and now has completely changed it up to military/dark/sad/etc.  One of the first reactions I heard from people were that she has joined Jay-Z and the Masons, which could be valid but to tell you the truth I have no clue.  Right here today I had a chance to check out her video to this song "Hard" featuring Jeezy, and the video has left me somewhat confused.  The beginning of the video has Rihanna as a general or sergeant playing into the beginning of the song.  Later she goes on to walking in a desert avoiding bombs and gunshots while continually singing her song.  We get our Jeezy appearance here which is pretty on point and he does his thing, but then Rihanna comes up sitting on a tank wearing a Disney World hat, or atleast that's what it looks like.  Summary aside my question is,  what is Rihanna's direction now?  Does anyone know or are they just trying to mix everything up in a pot and see if she will appeal to everyone?  Well here is the video, and if you have any comments please share them...
