Reinforcing unaligned players

There are all sorts of little scenarios where being forced to have someone else's troops in your town -- who is not necessarily your friend or ally -- could cause problems, especially little resentments. As Rill pointed out, it can pin a player down..or, the player receiving the reinforcements might decide they don't like the player, or would prefer troops from another player..there could be an issue of "I don't want to be responsible for the death of someone else's troops"..it could even be used for extortion. And no, most of these scenarios seem highly unlikely. Doesn't mean they're impossible.

The main point is that I don't think one can be forced to accept an occupation from someone else (comments about the real world notwithstanding). There needs to at least be a choice, or a way to designate someone as a "friend of the realm" or something. [As a thought, the ability to keep troops *out* could be dependent on building a wall..if they could just walk through the streets, it would be hard to expel them without a fight..]

Since not being able to get into a town would defeat the good intentions of the reinforcer, perhaps the army would set up camp outside of the town, as a sort of alternative blockade, and their support be worth a certain percentage of the full amount.
