The Red Army was the armed force first organized by the Bolsheviks during the Russian Civil War in 1918 and that, in 1922, became the army of the Soviet Union. "Red," a symbol of communism, refers to the blood shed by the working class in its struggle against capitalism.
The Red Army scored its first major victory over the Germans in early December of 1941 when it defeated the Wehrmacht outside of Moscow and pushed them back from the capital. However, news of this success was largely ignored in the US as the Japanese conquered Hawaii, the key to the Pacific Ocean.
After the first attempt to take Hawaii failed, the Red Army was fighting the Germans again, this time as they pushed into the Caucasus and Stalingrad. The Red Army fought furiously to hold the city, and in the winter of 1942, launched an offensive that encircled the Germans and retook the city. However, although the defeat had been disastrous for the Germans, they were far from beaten proving that they were still a dangerous threat to the Red Army.
After their victory the Red Army stormed west, but the German Army was far from beaten. As the war progressed, Soviet Leader Leon Trotsky kept calling for a second front to take the pressure off the Red Army, but it wasn't until later in the war that Joe Steele realized that the Red Army was going to win. After Operation: Overlord, the combined Red Army and Allied Armies smashed Germany between them.
After the US invaded Japan, Trotsky wanted a piece of the Japanese pie and ordered the Red Army to invade too. They did and the island was successfully conquered and divided between the two the U.S. and the USSR.
The Red Army had been beaten by the Wehrmacht during Operation Barbarossa and finally, surrendered at Kuibishev. Towards the end of the fighting, the Red Army had fought with almost suicidal zeal, leaving many Germans who had battled against them with lasting memories. Although defeated, many Red Army veterans became partisans, and were still fighting against the Axis when the Wehrmacht marched into India in 1947.
The Red Army paid more than their fair share for the Allies' victory in World War II. Even after the war was over, the Red Army continued to pay a hefty price at the hands of the German Freedom Front, although they were able to inflict just as much terror on the GFF and German civilians alike.
Still, the occupation cost the Red Army some of its best and brightest, including Ivan Koniev and Georgy Zhukov. And unlike their own people, the German fighters became even more violent and occupation strategies had to be revised to prevent civilians from joining the insurgents.
Unlike their Western counterparts, the Red Army continued to occupy their assigned quarter of Germany completely after 1948. Even though they were determined to stay and install a communist government, officers of the Red Army and NKVD alike admitted it would be a hard occupation.
Although the Soviet Union joined the 1938 war against Germany, the Red Army was not fully deployed. Some troops were allocated to defend Czechoslovakia, but it was the Soviet Air Force who carried most of the burden. This was because the Soviet Union was separated from Czechoslovakia by Poland and Romania, two countries the USSR had made territorial claims against and which would have declared for the Axis had the USSR crossed their territory without their permission. Czechoslovakia fell by Novebmer, 1938.
As an official state of war continued to exist between the USSR and Germany, well into 1939, when the Soviet Union finally deployed the Red Army into Poland, claiming that Poland had interferred with the Soviet Union, and that the Polish government had persecuted ethinic Russians in its borders. Poland engaged the Red Army, and invited German forces to assist.
During much of World War II, the war against the Race's Conquest Fleet, and the Colonization period, the Red Army was commanded by Marshal Georgy Zhukov. It worked along remnants of the GermanWehrmacht to fight the Race forces, using the Soviet Union's vast land area to constantly outflank the enemy. When the Race prepared for its invasion of Britain, it withdrew a majority of its units from both Germany and the USSR, allowing the Red Army to prepare more defenses when the depleted Race forces returned.
Vyacheslav Molotov relied on the Red Army both for the protection of the USSR's territorial integrity and, to some extent, the nation's internal security. The latter was especially true in the early 1960s when Molotov had to purge the NKVD of agents who had supported Lavrenty Beria's coup against Molotov. Throughout, Molotov was uncomfortable with his reliance on the Red Army; he considered them, and their leader, Marshal Zhukov, as likely as the NKVD to attempt to overthrow him. When the NKVD and Red Army were equally suspect, he played the two against each other; when the Red Army saved him from the NKVD, he had no choice but to support it over its rival organization, which put him in a very vulnerable position indeed.
However, the Red Army never did attempt to replace the government, certainly not during Molotov's lifetime.
