From the translation in the OP of this thread:

1980's Europe

The utter failure of operation Palaiologos in 1978 brought with it the understanding that humanity was severely outnumbered in Europe. The main BETA offensive restarted the following year, making the forces of the Soviet Union retreat first west of the Urals, then further - until humanity's defence line ran through Poland and Ukraine. Their next logical targets would be East Germany, Czechoslovakia, Hungary and Romania, - but these would use terrain to their advantage, building defensive lines on the Oder and Danube rivers, and the Carpathian mountains, managing to complete them before the fighting in Poland and Ukraine was over. As a result, the BETA advance was checked, and from 1980 the situation stabilised.

In January 1983, the BETA are held back by the Oder-Neisse, Carpathian and Transylvanian defence lines, as well as two beachheads (Kurland and Pomerania), which all served to separate the BETA forces, as well as evacuation centres for the large numbers of refugees from countries west of Poland. However, as time passed, the strength of the BETA only grew, and with them the fear of a successive collapse of the front line. The main strength of these lines was comprised of Warsaw Pact troops, with Western countries such as Britain and West Germany providing assistance as part of UN forces, and a common front was never agreed upon. Humanity, still divided by the Cold war order, was facing their greatest threat yet.
