In the editor depot there is a custom formations script that you might be able to use. I do not think it will make the trailing guy watch your six when you stop, but that could be done with an additional script. You could make a script that tells the trailing guy to dowatch in the direction opposite his last movement direction. You could also script the second guy to always look to the left and the third to look to the right. But this can also be done by direct commands during play. Since this will be a good addition to a mission I have been working on, I will toy around with it and post the script on the edditor depot when I am done. Maybe I can make a new script to accompany the custom formations script that also incorrporates "dowatch" direction for each squad member (if that is not already in there).
