Objective 1 : Destroy the Flakvierling anti-aircraft cannons. [2]

As soon as the mission starts, get behind some cover and take out the roughly five German soldiers you can see down in the field. They're hiding behind rocks, so keep an eye out. Once they're down, move to their position. It's a good idea to swap out your weapons for theirs if you prefer them, as the British weapons aren't the best.

Next, peek over the small ridge in front of you. You'll need to take out the Germans in the bunker and any in the trench leading to it. Keep pushing forward over the hill, doing the same thing – spotting and eliminating enemies – until you reach the bunker with the MG42 machine gun.

When you get to the MG42 bunker, you'll know it when you see it. Switch to your sniper rifle. Carefully aim down the scope and slowly step sideways until you can just barely see the MG42 gunner. Take him out quickly before he can get you!

After dealing with the MG42, move behind the rocks at the base of the hill where the gunner was. From here, use your sniper rifle to take out all the German soldiers defending the Flakvierlings. If you have grenades and feel like it, toss a few around to clear out any stubborn enemies.

Finally, to destroy the Flakvierlings, you'll need to plant explosives on the yellow markers. Just get close and interact with them to plant the charges.
