I'm enjoying my second solo game. Question: Rule 13.1.3 states that a unit in a uncontested area can fire at an enemy unit in a adjacent area (unless armor is present).
What happens if units of both sides are in the target area? I've got a German infantry unit in a wooded area that I would like to fire on a Soviet unit in an Urban area from the rear. (That Soviet unit is about to engage in close combat with other German units).
