Mass movement in PC?

[Green]

Double click on the formation HQ and right-alt click where you want it to go. A red arrow will appear from the formation to the target hex. Check in the AI orders drop down dialogue that only the formation you actually want to move has been selected (delete any subordinate formations you don't want to move - you will have seen red arrows indicating all movement anyway), then activate AI movement from the drop down menu. Select the HQ carefully. All units subordinate to it will follow the move order, I believe.

It's not very efficient though. You will get the formation moved faster by doing it manually. I guess it's the same mechanics the AI opponent uses, so it might even things up a bit vis a vis the AI (if you were ever playing against the AI) to move like that, but in a PBEM game I wouldn't do it.

Lol. I'm sure Green's email is clearer than this. Jut noticed that he already responded. Sorry.

Actually I suggested the Immediate A/I Orders as opposed to the Deferred A/I Orders that you have described. I feel I have more control that way. But neither works perfectly since the AI does not work perfectly. It can be handy but needs to be used with care.
