Q: The 100th Shipborne Fighter Aviation Regiment was formed at Saki in the Crimea on 10 March 1986. In January 1992 its personnel refused to take the oath of loyalty to Ukraine, which would have presumably made them part of the Ukrainian Navy or Ukrainian Air Force, and instead its personnel left for Russia, leaving their aircraft and equipment behind. The unit regrouped at Severomorsk-3 as part of the Northern Fleet. However, in February 1993 the regiment was disbanded and its personnel and equipment incorporated into the 279th Shipborne Fighter Aviation Regiment. The 279th Independent Shipborne Assault Aviation Regiment was established in 1973. In 1990 it became a Maritime Assault Aviation Regiment. On 22 February 1993 it was renamed the 279th Shipborne Fighter Aviation Regiment as it absorbed the remaining elements of the 100th Shipborne Fighter Aviation Regiment.
How many years did the 100th Shipborne Fighter Aviation Regiment and the 279th Shipborne Fighter Aviation Regiment both exist independently?

Q: The German government led by Adolf Hitler and the Nazi Party was responsible for the Holocaust , as well as for killing of 2.7 million ethnic Poles, and 4 million others who were deemed "unworthy of life" as part of a programme of deliberate extermination. Soviet POWs were kept in especially unbearable condition, and, although their extermination was not an official goal, 3.6 million of Soviet POWs out of 5.7 died in Nazi camps during the war. In addition to concentration camps, death camps were created in Nazi Germany to exterminate people at an industrial scale.Nazi Germany extensively used forced labourers. About 12 million Europeans from German occupied countries were used as slave work force in German agriculture and war economy. Soviet Gulag became de facto a system of deadly camps during 1942-43, when wartime privation and hunger caused numerous deaths of inmates, including foreign citizens of Poland and other countries occupied in 1939-40 by the USSR, as well as of the Axis POWs.By the end of the war, most Soviet POWs liberated from Nazi camps and many repatriated civilians were detained in special filtration camps where they were subjected to NKVD check, and significant part of them was sent to Gulag as real or perceived Nazi collaborators.
How many million Soviet POWs survived the concentration camps?

A: 2.1

The terms of the agreement provided that the materiel was to be used until returned or destroyed. In practice very little equipment was in usable shape for peacetime uses. Supplies that arrived after the termination date were sold to Britain at a large discount for 1.075 billion, using long-term loans from the United States. Canada was not part of Lend Lease. However it operated a similar program called Billion Dollar Gift and Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain and other Allies.
