Sprint after Pierson when he exits the tower. Find cover and toss a grenade at the enemies attacking from behind the sandbags. Follow Pierson when he advances into the trenches. Take your machine gun out and have it ready to attack the enemies guarding their fortification.
Stay low; there are only a few Germans in the trenches. Your machine gun and your experience should make short work from them as they try to attack from cover.
The target is at the end of the trench: the AA Gun. Press the Activate button to jump on the back of the AA Gun. This sequence is very similar to a previous one. Just keep shooting at the planes as they fly in patterns over the bridge. Lead the planes with your flak to inflict the most damage. About halfway through this sequence, the planes will start attacking in groups. Focus on taking them out before they can swoop in to kill you.
Defender
To earn this achievement/trophy, you must shoot down every plane. Note, however, this doesn’t include the planes that attack once you run out of ammunition.
When your gun dry clicks, a P-47 Allied plane swoops in to pull you out of the frying pan…
