Isolated Units

[Gregor]

Isolation occurs when you start your turn unable to trace a path back to any supply source.

A path is blocked by enemy units, ZOC (if not a friendly unit in the ZOC), impassable terrain and mines.

Think that's the basic of it.

The test are only at the start of your turn and units keep their status until your next start of turn when a new test is run.

Edit: from the user manual:
Supply Determination
When supply issues are being resolved for a unit in a given hex, the supply
value that applies to that hex is used. If there are no Supply Sources in the
scenario for that side, then the Global Supply Value is used for this purpose.
Otherwise, the Supply Source of highest value affecting that hex is used. If the
unit is Isolated, then the supply value in the hex is 0. Otherwise, the unit must
trace a line of communication (a line of hexes free of enemy units and their
Zone-of-Control crossing rivers only using bridges or ferries) to any Supply
Source hex or map edge ground hex when Supply Sources do not exist. In the
absence of Supply Sources, any map edge ground hex is essentially a Supply
Source with that side’s Global Supply Value. If there are Supply Sources used
for that side in the scenario, then the unit must trace a line of communication to
a Supply Source rather than ground edge hexes. When determining this line of
communication, the presence of friendly units negates enemy Zones of
Control.

Thanks Gregor. But then I am not sure why these 3 units are isolated.

[Gregor]

And there are no mines or impassable terrain there, and only the 4 highlighted units are isolated?

Then I don't know, seems strange...

The pic showed up twice for some reason ...

Cannot see Mines or impassible terrain. The 2 Daimlers have a wreck in their hex.

Seems there should be a path back to one of the 2 supply routes? Does the path have to be along roads?

Gerry what scenario are you playing? In addition to mines there could be hidden enemy units. You could move right on past them and never know if you don't recon or draw fire.

A bit more did the units move or this where everything started the turn?

[Ricky B]

And no the path isn't limited to roads. It sure seems like the units are in mines as that is the only thing that comes to mind that explains why.

Thanks Rick. It's a Goodwood one, Fifes and 23rd Hussars. Trying to remember when I took the screenshot but it may not have been at the start of the turn so units may have moved.

I did check for mines at the time. Finished and no hidden units have popped up. But I may have missed something.

Now at the scenario end I only have one isolated and they are in a minefield.
