English football league system: The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with six teams from Wales and one from Guernsey also competing.  The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system, although in practice it would take a team at the bottom levels at least two decades of consistently finishing at or near the top of each successive league to reach the top level, and even then additional restrictions, particularly in regard to stadium facilities, would then come into effect at the highest levels that could prevent a club from being allowed access to the top levels.  There are more than 140 individual leagues, containing more than 480 divisions.

List of Soviet divisions 1917–45: The Soviet Union's Red Army raised divisions during the Russian Civil War, and again during the interwar period from 1926.  Few of the Civil War divisions were retained into this period, and even fewer survived the reorganization of the Red Army during the 1937–1941 period.  During the Second World War 400 'line' rifle divisions (infantry), 129 Soviet Guards rifle divisions, and over 50 cavalry divisions as well as many divisions of other combat support arms were raised in addition to the hundreds of divisions that existed in the Red Army before Operation Barbarossa.  Almost all the pre-war mechanized and tank divisions were disbanded during the war.  There were also Red Air Force aviation divisions, and the NKVD divisions which also took part in fighting.  However, in contrast to Wikipedia's reasonably complete descriptions of U.S., British, and German divisions, only a few Soviet divisions have articles here, mostly because the detailed histories have either not been translated from Russian or have not been fully released from the official archives.
