Diplomacy - Suggestions

[therother]

I think a better and more real solution is that the garrison stays if you bribe them. In the field I can imagine an army disappearing, but what's the point of a garrisson disappearing? They are probably pretty comfortable in the city. Or maybe they should leave on the 2nd year (4th turn).

I think that this is a consequence of a creative decision by CA. They don't want troop types from one faction to be in the army of another, except as mercenaries, and there are strict controls on them - where you get each unit type, frequency and regeneration of each unit, and so on. Plus the garrison doesn't always disappear. If you can build the units, you get them.
