Shoot the machine gunner inside and jump into the trench behind the bunker

Follow the trench and easily kill a dozen Germans to the back of the bunker, enter the bunker and clear out four or five Germans. Follow the minefield signs to meet up with your teammates behind the truck and together you will attack the estate in front of you, clearing the area of about 30 Germans, go to the first floor of the small building and use the sniper rifle to kill the Germans ambushing the orchard.
