The 52nd NW unit has a plethora of choices. Options 2,3, and 6 are already stacked "danger density" orange.
Options 1,7,8, and 9 are off the road. Options 5, and 7 would cost a lot of movement points to get there leaving
few for follow up combat rounds. Options 1, 10, and 11 would only support attacks on one Soviet unit. Overall,
I guess I'd say 4 is the best since it's on the road and supports attacks on a Soviet division. And a check with the attack planner dialog box shows that it can participate in
the first combat rounds attacks:
EDIT: changed later to just go to tac. res. mode in the destination hex.
