Isolation question

[ComradeP]

(Note in advance: I tested this in FWWC, as it's easier to do there, but I have no reason to believe the situation in PzC is different) It applies either across a river hexside or into, but not "across" a full water hex.

In other words: a unit being ferried into a full water hex by a unit with a Has Boat flag will be in supply, but when it reaches the other side it will be Isolated unless it can trace supply to a supply source. The engineer unit can't supply it.

Technically, such a situation can persist indefinitely provided conditions are met. The engineer unit and/or the units on the other side of the river hexside can move and supply/be in supply as long as they're adjacent with the river hexside in between.

Note that although an engineer unit needs full MP's to ferry units across a river hexside, it doesn't need to end a turn with full MP's to be able to supply units across a river hexside the next turn. MP's are fully "recharged" before the supply check. In the case of your example, the Soviet engineer unit(s) blowing up the bridge ended Soviet turn 10 with 0 MP's due to damaging the bridge consuming all MP's, but could still supply the unit across the river at the start of turn Soviet 11 as it/they had full MP's.

The easiest way to put an end to a situation like this is shelling/bombing/firing at the engineer unit. As soon as it is Disrupted or Broken, it can no longer supply units across a river hexside (as it can't ferry units across such a hexside when Disrupted and thus prerequisites for supplying a unit across a river hexisde are not met in that situation).

Units with their backs to a river are very vulnerable and likely to suffer additional losses caused when they're Disrupted/Broken and there's no valid retreat path. Obviously, stacks of A quality units are still very difficult to deal with even in that situation as they can't Disrupt unless their morale drops to B in some way.

Disrupted units also can't be ferried "back" across a river (hexside or full water hex), so they're usually doomed when persistent pressure can be applied.

In FWWC, only engineer units with a Has Boats flag can ferry units across river hexsides.
