I personally love that level and I think it rivals Omaha as one of the best of the game. The trick is to move very slowly through the town. I mean, it took me over an hour to do it. Moving slowly also means that the rest of your squad will stay out of firing range, thus making it easier to get them all through safetly. Your medic will come up once in awhile and heal you if you need it, just make sure he doesn't get hit.
So the strategy is to move slowly through the town. Try to lure the enemy snipers into shooting at you and use that to discover where they are. Check the rooftops! There's atleast 3 in that level that you can just barely make out their head and if you don't get them, they'll knock out your other team members with relative ease.
Also, keep you eyes on any bell towers off in the distance or any bombed out buildings. I believe that early on in the level, a P51 flies overhead and drops bombs on a nearby house...actually it reveals 2-3 enemies who will snipe you to death if you don't clean them out.
That's really the philosophy though. Think of yourself as an exterminator sent out to rid each area of it's snipers. Make sure to explore every inch of the map and if you discover yourself getting shot at, stay out of that snipers line of sight until you clean him out.
