Supply for stealth units?

It would be neat if they needed supplies, but had to live off of whatever was left after the owner had taken what was needed (and this happened without any hint to the owner, of course). It makes sense, an army sneaking through someone else's land still has to eat, but if they're to remain hidden they have to eat only what they can scrounge without raising suspicion...

Yeah, especially since it makes no sense that they will starve while hiding in friendly territory, but find food while hiding in enemy territory.
