As far as most newspaper readers and television viewers are concerned any vehicle that is armed and armoured is a tank whether it has tracks or wheels. And indeed in some cases a definition is hard to frame. But there is one class of armoured vehicle about which there can be no question as to whether it is a tank or not - the Main Battle Tank. The term first came into use in the 1950s and has replaced such classifications as medium, cruiser, and heavy and medium gun tanks. The function of a modern battle tank is to strike the enemy from a distance and to be able to close with the target while at the same time being to a considerable degree protected. Nine countries manufacture main battle tanks today: France (AMX 30), Germany (Leopard), Great Britain (Chieftain), India (Vijayanta, Vickers Battle Tank), Japan (Type 61), the Soviet Union (T62 and T72), Sweden (S-Tank Strv 103), Switzerland (Pz 61 and 68), and the United States (M60 series). As well as these there are earlier generation MBTs still in use in a number of armies: the British-built Centurion, the Russian T54 and T55, and the American M47 and M48 (the M47 being now almost completely phased out). The AMX 30, Leopard, Chieftain, Vickers, T62 and M60 have all been exported and are in service in armies other than their native ones, as are all the earlier generation MBTs listed above. As an example of overseas sales the Russian T54-55s may be cited. It is estimated that to the end of 1975 the Russians had sold some 15,000 of these tanks around the world from Vietnam to the Middle East. Two countries, China and Israel, may also be building their own MBTs which they have designed themselves, but are more likely to be simply developing and adapting imported or acquired vehicles. This book contains Profiles of eight of the most important MBTs in service today. The other current MBTs are the Japanese Type 61 and its successor, the Swiss Pz 61 and 68, the Vickers (Vijayanta) and that most durable of MBTs (so long in service indeed that it was first built before the term came into existence and has in its own existence spanned more than half the history of the tank): the Centurion. drive had double reduction gear trains.
