Add a Food cost to Occupying armies?

Just a thought I had while sending an army out to occupy. How will they survive? At first I figured NPC animals, but when I send my armies against NPCs, they usually result in casualties, so that can't be it!

Wouldn't it be interesting if armies had food/h costs when occupying? Like, each unit type had a food cost, so if you sent, say 1000 militiamen to occupy a spot for 12 hours and each militiaman had a food cost of 1 f/h, you would have to send 1000*1*12=12000 food to sustain them? The exact number could obviously be adjusted.

I like it because it gives you more to think about when sending troops to occupy a spot. Send more troops for defense, or send fewer/call them back sooner to conserve food?

Wow, you're making your troops pay for their own rations when their out on YOUR military orders ? What a tyrant.

But you make a point. The realism aspect of the game was only a supplementary argument I made, since I think it would be an interesting mechanic anyway.

I dont think there should be a food cost for occupying troops.

When you try to make game realistic, probably you are going to lose all the fun....
