That's only because it used a casemate instead of a turret.
Anyway, here are my notes:
Panzerkampfwagen II Leopard:
This is a Main Battle Tank, and the successor to the Tiger, which resembles the Merkava in appearance. Components from the Tiger are used whenever possible for easier logistics. It is built around a stabilized 12.8 cm KwK L/65 (that is, the gun has a barrel length of 65 calibers), longer than the main gun of the historical Maus, and is also armed with a coaxial machine gun, two remote-operated roof-mounted machine guns, and an internal 5cm mortar.
It uses digital fire control systems, a laser rangefinder, a rear-mounted pancake turret and a front-mounted 1500 hp turbodiesel engine. It uses an 8-speed transmission, also front-mounted, a torsion bar suspension, conventional road wheels, and a long-range radio.
Its low profile hull has an armor scheme of 128/96/64, with a 71 degree slope on the front, while its turret armor scheme is 192/128/96. Said armor scheme values do not include the thickness of the add-on reactive armor, however. It uses integral spaced (meaning the armor has a hollow layer within for defeating HEAT rounds, like in the Leopard 1) composite armor on both the hull and the turret, has NBC (nuclear, biological, chemical) protection, and also uses side skirts to cover the wide armored tracks (It shouldn't bog down in the mud or the swamp!), which in turn cover the sides of the hull, for extra protection. It is equipped as well with layered RRA bricks on the front and sides of the tank. To protect against mines, an armored, sloped and corrugated hull floor is used.
It is capable of neutral steering, and carries a crew of four (commander, driver, gunner, loader), which can enter and exit the tank via turret hatches on top and the clamshell rear doors on the rear of the hull.
Similar to the Merkava, design focus is given to crew survivability. All tank components are designed and arranged to act as extra armor for the crew, especially against frontal attack. Various safety measures such as blow-out panels, armored walls and doors, spall liners and automatic fire extinguishers are installed to protect the crew in case of fires, spalling and explosions, as well as to reduce the chances of those events happening. Internal air conditioning is also provided for crew comfort and NBC protection.
Lastly, it has the latest technological developments, is painted in camouflage patterns, has reduced noise and heat emissions, is easy to produce, operate, maintain and repair, uses VK materials, and has two versions: one that uses the 12.8cm gun, and one that uses an equivalent laser cannon instead.
