Here according to the Soviet era defector Suvorov and posted in entirety.

Lessons learned that the troops now arrayed on both sides of the border Russia and Ukraine had better learn fast!

"The winter of 1969 was an exceptionally bitter one in the Soviet Far East. When the first clashes with the Chinese took place on the river Ussuri, and before combat divisions reached the area, the pressure exerted by the enemy was borne by the KGB frontier troops. After the clash was over, the General Staff held a careful investigation into all the mistakes and oversights which had occurred. It was quickly discovered that several KGB soldiers had frozen to death in the snow, simply because they had never received elementary instruction in sleeping out in temperatures below zero. "

ZERO temperature as in degrees Centigrade. That is thirty-two degrees Fahrenheit. The freezing point of water.

"This was alarming news. A commission from the General Staff immediately carried out experiments with three divisions, chosen at random, and came to a depressing conclusion. Wartime experience had been irrevocably lost and the modern Soviet soldier had not been taught how he could sleep in the snow. Naturally he was not allowed a sleeping bag and of course he was forbidden to light a fire. Normally a soldier would spend nights when the temperature was below freezing-point in his vehicle. But what was he to do if the vehicle was put out of action?" 

"The chiefs of staff of all divisions were immediately summoned to Moscow. They were given a day's instruction in the technique of sleeping out in snow at freezing temperatures, using only a greatcoat. Then each of them was required to convince himself that this was possible, by sleeping in the snow for three nights . . . Then the chiefs of staff returned to their divisions and immediately the entire Soviet Army was put to a very hard test-that of spending a night in the open in numbing cold and without any extra clothing . . . Thereafter, spending a night in the snow became a part of all military training programs."

SPEND SEVERAL NIGHTS IN THE SNOW CLAD WITH AND PROTECTED FROM THE COLD BY A GREATCOAT! THAT GREATCOAT MADE OF HEAVY WOOL AND FULL LENGTH [BELOW THE KNEES IN MOST CASES AND OFTEN DOWN TO THE ANKLES] CARRIED AT ALL TIMES BY THE SOVIET TROOP DURING THE SECOND WORLD WAR!

Read and heed Russian, Ukrainian, NATO! And be prepared. NOW!
