Fixed Units release criteria

[ComradeP]

If a formation is supposed to be released when the enemy has captured a certain location or reached a certain point on the map, a "tripwire" unit will need to be placed there to make that happen. "Released when hex X,Y is controlled by the enemy" is not possible.

Depending on the scenario, releases may or may not be random. In many cases, release chance is 100%. As releases are usually checked per turn, it won't take that long for formations to be released if the percentage chance isn't 100% unless they have a low release %.

Releases can be a bit problematic if they're not set to T in scenarios with low visibility or terrain obstructing line of sight as parts of a formation might be released whilst others are bypassed by the enemy whilst remaining Fixed.
