Matilda
 
The Matilda II was a British infantry tank that played a significant role in World War II, particularly during the early years of the conflict. Introduced in the late 1930s, it was heavily armored for its time, with thick sloped armor that provided excellent protection against enemy fire, particularly from anti-tank weapons.
The Matilda II primarily served in the North African campaign, where its armor proved to be highly effective against Italian and early German tanks. Its reliability and durability earned it the nickname "Queen of the Desert" among Allied forces.
 
Despite its formidable armor, the Matilda II was hampered by its relatively weak armament, consisting of a 2-pounder (40mm) main gun, which struggled against heavily armored German tanks encountered later in the war. However, its role as an infantry support tank and its ability to absorb enemy fire contributed to its effectiveness on the battlefield.
Overall, the Matilda II played a crucial role in the early years of World War II, providing Allied forces with a heavily armored and reliable infantry tank that proved invaluable in various theaters of the war.
