Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
Valentine tank
The Valentine was extensively used in the North African Campaign, earning a reputation as a reliable and well-protected vehicle. The first Valentines went in action with the 8th Royal Tank Regiment in Operation Crusader. The tank first served in Operation Crusader in the North African desert, when it began to replace the Matilda Tank. Due to a lack of cruisers, it was issued to armoured regiments in the UK from mid-1941. The Valentine was better armed and faster than the Cruiser Mk II. During the pursuit from El Alamein in late 1942, some tanks had driven more than by the time the Eighth Army reached Tunisia.
The Valentine shared the common weakness of the British tanks of the period, its 2-pounder gun lacked high-explosive (anti-personnel) ammunition and soon became outdated as an anti-tank weapon. Introduction of the 6-pounder in British service was delayed until the loss of equipment in France had been made good, so the 2-pounder was retained longer. The small size of the turret and of the turret ring meant that producing mountings for larger guns proved a difficult task. Although versions with the 6-pounder and then with the Ordnance QF 75 mm gun were developed, by the time they were available in significant numbers, better tanks had reached the battlefield. Another weakness was the small crew compartment and the two-man turret. A larger turret, with a loader position added, was used in some of the 2-pounder versions but the position had to be removed again in variants with larger guns. Its relatively low height was an advantage in a battlefield with little cover, allowing it to take up a "good hull-down position in any convenient fold in the ground".
