Ideas for ranks

Maybe a bit more diverse with each rank. Instead of having the basic; warrior, hunter, medic, etc. Shake it up. For example: Maybe "rats" which can be a challenging rank in which the character will be set off to join the rivaling pack for information. This can shake up things between the packs and make things more exciting for the members during role play.
(Maybe a court-like system of the higher up's? The usual beta etc.)
In previous packs of mine I noticed that hunting and combat ranks were often bored due to lack of action. I had tried giving the combat ranks various "chores" to do. Scavenger hunts for various objects which could be crafted into weapons or for selling purposes. Same for hunters. (Although I don't know how evolved you guys plan for the packs to be, my pack way back when had chemists and various science ranks as well as tools.)
Which is another idea; chemist ranks? They were booming in previous packs of mine but then again I'm not sure how it would tie into the plot. Though with dying things in the city I suppose gases from corpses would become a problem? Dunno
Another thought, maybe for combat ranks, during training (I don't know how y'all train but I trained in batteries) maybe have then learn formations? Just an idea. ^^

Well that's my rant c:
