PC ZOC Question

[Liebchen]

If my units had established ZOC first, shouldn't that prevent him from moving adjacent to my units and isolating and cutting them off?

From your wording, I suspect that you may be misunderstanding the ZOC rule. It does not matter who establishes a ZOC first. Enemy units can assert a ZOC simultaneously, over each other's hexes and over mutually controlled, yet unoccupied hexes (i.e. no-man's land).

Just because a hex is in an enemy unit's ZOC does not prevent me from moving my unit into that hex. If it did, then there would rarely be any combat.

As a matter of fact, you are in apparent danger losing that isolated stack of units completely, if you don't follow Foul's advice immediately. This would come from the unit on the south edge's moving southwest and then north, rendering your isolated units un-rescue-able. This result would be because, while you may usually move your units into an enemy ZOC, you cannot move from an enemy ZOC directly into another enemy ZOC. (The sole exception, as Foul pointed out, is from a friendly-occupied enemy ZOC to another friendly-occupied enemy ZOC, which you wouldn't have.)

Please accept my apology if I have misunderstood your question.
