If a minion is on top of your deployment stack and you can make any amount of progress with it by deploying, it must deploy. If a minion is on top of your deployment stack and it can only reach a hex that is the same distance from its mark as its starting hex, it can optionally deploy to move to that hex. If a minion is on top of your deployment stack and it can only reach a hex that is a further distance from its mark than its starting hex, it cannot deploy.
