These legendary tanks have been in combat for 70 years. These formidable, ultra-reliable, inexpensive to manufacture and easy-to-operate vehicles have become the standard of world tank building - even NATO strategists calculated the power of their tank forces in the "fifty," which were the first in the world to be equipped with an anti-nuclear defense system and capable of fighting in a nuclear war. In addition to the Soviet Army, T-54 and its "most advanced modification" T-55 were in service in 67 countries and fought on all continents - from the suppression of the Hungarian rebellion of 1956 to the defeat of Georgia in 2008, from Vietnam and Afghanistan to Yugoslavia and Desert Storm, from the Arab-Israeli, Indo-Pakistani, Kampuchean, Vietnamese-Chinese, Iranian-Iraqi and Lebanese wars to Angola, Sudan, Ethiopia, Somalia and Chad, from Transnistria, Karabakh, Abkhazia and South Ossetia to Libya and Syria.
