Ok! What this will do is, whatever the formation, when
you set the direction eg. 045 The units will face that dir.
This will cause a group in the line formation moving N,
facing north, when you use the command to look 045
the moment they stop the group will look NE and the line
of men will now not be running W to E BUT NW to SE.
So this is not quite what you may be needing, but you
could have groups to change position according to terain.
Hope this may help!
