The best option is not to get involved in them, if you have to attack in these situations move slow & suppress them before you go. So if its due to being a dark night a walking barrage in front of you otherwise try & work units round to support at greater range or so you can attack the hex from several adj ones if its woods or such preferably with people behind to catch the runners.
Military commanders generally try & avoid confruntations in close quarters like urban for the simple reason they hurt.
Good scouting helps to so you have an idea what you are taking on.
