I guess I'm being too lazy to rebase WWg on 40 x 40 bases as opposed to 40 x 80 (2.2). I've forgotten how to move these things on the table top. They can only move forward on the narrow, 40 mm edge am I correct? Thank you for helping!
I'm away from Purple at the moment, so I can't quote chapter and verse for you... Yes, WWg's do have a Front Edge, which is one of its 40mm ends. For them to make a Group Move, a WWg must all be facing the same direction as other elements in the group (with all the usual restrictions of Group Moves). But, individually, a WWg may make a tactical move in any direction. Of course, you'll pay dearly in PIP's to do this, but, yes, can be done.
