The FV4201 Chieftain was the primary main battle tank (MBT) of the United Kingdom from the 1960s into the 1990s. Introduced in 1967, it was among the most heavily armed MBTs at the time, mounting a 120 mm Royal Ordnance L11 gun, equivalent to the much larger specialist heavy tanks in service. It was also among the most heavily armoured, with up to 195 mm (7.7 in) that was highly sloped to give 388 mm (15.3 in) thickness along the line of sight.
Read on WikipediaA tribal chief, chieftain, or headman is a political leader of a social group commonly described as a tribe, clan, band, or confederation of tribes. Chiefs’ authority varies widely by society and context, and in many cases depends on consensus and customary legitimacy rather than coercive power. In anthropology, terms such as tribe, chief, and chiefdom have been used in comparative models of sociopolitical organization, but the analytic use of tribe has also been widely criticized as imprecise and historically burdened. In some contemporary states, forms of chiefly authority are formally recognized or regulated by constitutions and statutes.
