King Tiger or the Königstiger was the most powerful tank of ww2. Germans began to operate it late in the war but it proved effective with its firepower and thick sloped armor. However it so heavy that it consumed a lot of gas and gas was short in supply. So many Kingtiger left abandoned without fighting because of gas shortage.
M-113 is an armored personel carrier, the use of which began with the Vietnam war. Today, it was operated by many countries and upgraded with latest technology.
T-34 was the most produced tank of ww2. The simple design of T-34 made it easy to produce at large quantities. Also T-34 was the first tank to utilize "sloped armor" which caused the antitank arms to bounce off.
The American made Sherman was the main tank of the allies. It was light and therefore faster than any other German tank. But it lacked the firepower and armor which made Sherman vulnerable to German armored forces. But the number of Shermans deployed was so high that it posed a great danger to axis armies.
After facing the effectiveness of T-34, Germans began to design a new tank concept with a sloped armor just like theT-34 had. The result was the Panther.
