Squire class & posting your military units

I think it would be cool if i could set my archers up on towers near the edges of my towns so that they guard, the problem that exists though is they need to eat/sleep and it would take a lot of micro-managing to keep that up so I was wondering if anyone had a solution for this. If not, I’d like to suggest a squire like class that would bring your other military units food and things like that. Really enjoying the game and community so far, thanks all
