Any good anagrams for heavy tank?

Heavy tank was a class of tanks produced from World War I through the end of the Cold War. These tanks generally sacrificed mobility and maneuverability for better armour protection and equal or greater firepower than tanks of lighter classes. The origins of the class date to World War I and the first tanks; designed to operate in close concert with the infantry and facing both artillery and the first dedicated anti-tank guns, early tanks had to have enough armour to allow them to survive in no man's land. As lighter tanks were introduced, the larger designs became known as heavies. A similar 'breakthrough' role remained into World War II. As tank-v-tank combat became more common, heavy tanks mounted very powerful anti-tank guns. By the end of the war they were used both for dealing with heavy fortifications as well as antitank work. They were also known as breakthrough tanks, indicating their purpose of spearheading the attack. They were usually organised into specialised heavy tank units. The emergence of the main battle tank spelled the end of the heavy tank as a separate class, although a number of post-war examples were produced. These were generally gone by the 1960s.
