In a painstaking process this alternate history storyline has been researched and is presented for your entertainment.
By using historical documents from the US Joint Chiefs of Staff we know exactly what the contingency plans were in the case of an expected Soviet attack in 1946.
August 21, 1946 Pyrenees Mountains The Pyrenees Line
The foothills around the town of Vileha look like a WWI no-mans land. It reminds the few vets who fought at Monte Casino of old times. Except this time they are the defenders and the Soviets are regulated to playing their part. Ominously the Red Army has made headway by shear force of being willing to take losses. They are not making banzi charges or even suicidal charges but they are just not willing to give any ground once gained. Counter attacks are not the answer at this point and NATO troops where not capable of making them.
As the Germans found out, the Red Army soldier was able to fight under the most extreme of conditions. They fought through the Winter months just as their enemy did but they were able to handle the elements and deprivation better. They live on less food, supplies and many times worse leadership. Yet they prevailed against the most deadly enemy the world has ever known. That is until now.
The NATO troops facing them are gaining valuable experience in the art of defensive warfare. They may not be capable of attacking yet but they are becoming very adept at defending. They are finally receiving enough supplies to take the fight to Ivan. They can give as good as they take mainly because of their strong defensive positions. It's pretty easy to give em hell from the high ground.
Luckily for the soldiers on the ground, the air war is a stand off with neither side gaining the advantage. This favors the defender on the high ground. They have a manageable fear of being blasted out of their defensive positions by IL10 and TU2s. Both are remarkably versatile at a tactical level. The fighters continue to cancel each other out. A special operation here or there will gain a decided advantage for one side or the other but no clear cut winners.
Much like Monte Cassino this is a soldiers war. It takes grunts to take the high ground. Artillery can just make it unoccupied for a while. Air power can turn it to mush and debris. But only the grunt can take it and keep it. So far Ivan has been able to keep what he has won the hard way.
The shear numbers of Soviet troops and planes are gradually pushing the NATO forces back foothill by foothill. There will be no breakthroughs yet there will be no letup in the attacks either. Much like Monte Cassino on a grand scale. The Allied forces eventually took Monte Cas sino...eventually and at great cost.
Unnoticed by the Stavka at this early stage is that as the US units are being rotated back to the rear for R & R they are increasingly being replaced by Spanish, Portuguese, British, Canadian and other NATO forces as they become trained and able to take up their positions. Even units of Belgians, French, Polish, Dutch and Danes are appearing in small numbers. All have new equipment, training and supplies courtesy of Uncle Sam.
Ironically the smaller front and the uselessness of armor have freed up a large number of Soviet mechanized units who are being moved to other fronts. Again ironically the lack of any massive armored operations have decreased the Red Armies need for supplies and fuel.
If you are student of Management by Objective you will know that the first thing you look at is the trend. You ask yourself "if nothing changes what will be the outcome?". The outcome of this situation is that the Soviets will pierce the Pyrenees Line in 3 months... if there are no changes.
