Objective 2: Collect the drop
Inside the church you will come across three soldiers guarding this area, you should especially look out for the one by the barriers on the upper floor.
Gold Bar! 8/10 - At the very end of the church, right behind a crate.
Head to the end and turn left to find a set of stairs leading up. Afterwards go even higher, going up the planks. Look out for the sniper by the window on the right (if you haven't killed him before).
Wine Bottle! 2/4 - On the destroyed reinforcement on the very top.
Gold Bar! 9/10 - By the large destroyed church window.
Objective 3: Survive the German attack
Continue going upstairs [#7] until a cinematic starts, during which you will find a new sniper rifle. Unfortunately you will also be noticed and have to face three waves of German soldiers. Above all, look out for the sniper lurking in the opposite building and the machine gun stand.
Wine Bottle! 3/4 - On the floor in the opposite building, right beside the sniper..
Gold Bar! 10/10 - Behind the crate beside the weapon drop.
After the first wave ends, run downstairs to the second vantage point [#8]. This time, apart from infantry, there will also be an armoured vehicle - try to shoot one of its four red holes as fast as possible.
After fighting off this attack, it's time for the last one (while running to the vantage point [#9] you should look out for the soldiers who have appeared in the church). This time a tank will show up - try not to get shot, focus on destroying the vehicle in the first place.
Wine Bottle! 4/4 - On the street, right before the rubble.
Objective 4: Get out of the church
Start going down very slowly - try to shoot as many enemies as possible while still at the higher position. After reaching the main door, the mission will end.
