I played the campaign on "General" till the last scenario, the US West Coast... which I cannot win. Whatever strategy I use, I always cannot take San Francisco within the turn limit. The best try so far: I just would have needed one more turn to win.
My most successfull setup so far:
1. Two army attack groups, one smaller defensive group.
The first group consits of:
2x Elite Tiger II
1x Veteran Jagdtiger
1x Veteran Panther G
2x Hummel SPGs
1x Wurfrahmen (Nebelwerfer)
2x Ostwind
1x Scout Tank
2x Crack Infantry units
and the Rail Gun
The second group consits of:
3x Elite Panther G units
1x Wirbelwind
1x Wurfrahmen (Nebelwerfer)
1x Scout Tank
1x Crack Infantry unit
1x Brigde Pioneers
The third, defensive group consits of:
the AUX Stug III, Hetzer, Panzer IV and one of my Core Veteran Infantry units.
The Luftwaffe forces:
2x Me-262
2x Ta-152
2x Bf-410
3x Ju-87
1x Ju-188 (Elite with 14 units in reserve to destroy naval vessels!!!)
The battleplan:
While the first group moves straight west to Los Angeles and goes north from there to San Francisco, the second group is heading north-west to take Seattle and turns south to San Francisco, after Seattle is taken. The third group takes a defensive position near the starting position, to repulse the attack of combined US ground forces from north. After this, I send them north to take a couple of US cities to gain more prestige. I don't send them to the coast, because the units are realtivly weak and the way to the coast is very long, so they won't make any difference there anyway.
My main problems are the US Pershing tanks. I kill them all, but it takes way too much time to destroy them all without serious losses.
My second problem are the anti-air guns in L.A. and they bay area around S.F.. My Luftwaffe is able to shoot down all of the US Airforce and destroy the Navy, but losing to much strength to the AA guns. And I cannot get to all of the guns in time, because of the Pershings and entrenched AT guns.
Third problem is, the Stukas (Ju-87) have to fight for some turns in the east, because third group is not strong enough, to fight off the final US tank assault on their own.
I m trying to beat this last scenario for several days now with different setups and strategies, but I cannot win. I even replayed former battles, to spare more key units for the final scenario.
Any ideas or suggestions to it? Otherwise I'm going to loose my mind about this game.
