Could be a fun bit for character development too.  If your character wants to be tactical but is assigned a heavy weapon, or if he wants to start taking a leadership position but someone else has been granted that spot.  If he wants to be a leader and therefore he wants recognition he might be frustrated by being put in a Scouting or Long Range position.  Or really with following orders in general.

As a Hunter maybe that's something your guy wants to handle quickly, modifying his weapons or trying to finangle himself into a position with a stronger weapon. 

For example my character I'm planning to have quite a high opinion of himself.  Doesn't mean he's actually hot shit.  But might create an opportunity to get into a contest with someone else, or might result in him getting put on shit duty for being too haughty.  Or maybe events come to pass that quickly set him straight and give him some perspective.
