I guess this is the coop mission I've played the most, and I've got my own tactic I use for this. Take a sniper rifle (since they're now useable in Sabre Squadron without the stupid stamina drain thing). You might want to get a BAR from one of the Supply boxes, though you probably won't be strong enough. Hopefully you'll have some teammates to deal with the Italians that charge up the slope to the right of the bridge. If not, sneak around and throw nades at them. 8) Then, head immediately to the PAK 40 on the west side of the bridge. Lie down just to the west of it, near the cliff - this is a good sniping spot, from which you should only be visible up to 20 m or so. Remember to defend your PAK 40 from idiot teammates. If they go on it, shout at them. When they ignore that, TK them.
Lie down on the ground (make sure not to get your uniform too muddy) and snipe away at the enemies on the other side of the canyon. With the new SS sniper system, this is easy.
With any luck, your teammates will have the brains to remove the explosives from the bridge. Your job is to pick off all the enemies that poke their heads above the wall. Once the bridge has been secured, two Panzer IIIs will appear from the distance. Go and sit on the PAK 40. Don't bother firing at them until they've reached their resting spots - you'll only waste ammo, unless you're unusually lucky. Once they're at the village, open fire. It shouldn't be too hard to blow them up. Once the tanks are blown up, get off the PAK 40 and go back to your sniping position. Shoot all the infantry. Wait for the Tiger tank to appear from the west, and run back to the PAK 40. Shoot the Tiger as it crosses your field of vision, then run off the PAK 40, grab a BAR and deal with the soldiers that come up the western slope. There's also a chance the Tiger will blow up your PAK 40, which isn't good. :x If that happens, grab a clam bomb from a dead ally (or the supply box) and run down the slope to the east of the bridge, then run up to the other side and attach it to the Tiger. It should park in a spot where you can reach it without getting blown up or machine gunned. 8) You can also blow up the Tiger using the eastern PAK 40, but the chances are that some idiot has already wasted all the ammo.
