This is how the tank compares to other Western armored vehicles being sent to Ukraine.

Krauss-Maffei Wegmann (KMW), the manufacturer of the Leopard 2A6, says it can hit a top speed of around 43 mph, and has a 1,500-horsepower diesel engine.
Its main weapon is a 120 mm smoothbore cannon, while it is also fitted with a 7.62 mm machine gun and automatic grenade launchers. It can travel up to 280 miles without refueling, KMW's website states.
"The armed forces of 18 nations rely on the fire power, maneuverability, and outstanding protection of the Leopard 2," the website adds.

The US agreed in January to deliver 31 of its M1 Abrams tanks to Ukraine, despite its initial reluctance over potential operational and maintenance difficulties.
The tank matches the 120 mm cannon and 1,500-horsepower engine of the Leopard 2A6, and it also comes with an M2 .50 caliber machine gun and two 7.62 mm M240 machine guns.
The M1 can reach speeds of up of up to 42 mph and is crewed by four soldiers – a commander, a gunner, a loader, and a driver – as is the Leopard 2A6.

The Challenger 2 is "designed to destroy other tanks," the British Army website says, adding that it has been used "on operations in Bosnia and Herzegovina, Kosovo, and Iraq, and has never experienced a loss at the hands of the enemy."
Like the Leopard 2A6 and M1, the Challenger is crewed by four soldiers.
It has a 1,200-horsepower V12 diesel engine and can travel at speeds of up to 37 mph. It has an operational range of 340 miles.
The tank is equipped with three guns. Its main armament is a 120 mm rifled gun, while it is also fitted with a chain gun and a hatch machine gun.

The Gepard has an 830-horsepower engine and can hit a maximum speed of around 40 mph. It also has a fuel range of about 340 miles, Insider previously reported.
But it has been plagued with supply problems, however, as Switzerland, which holds a large stock of its ammunition, has declined to supply it, per Reuters.

The French government promised in January to deliver the AMX-10 RC armored reconnaissance vehicle, which sparked a debate over what does and doesn't qualify as a "tank," after France and Ukraine dubbed it a "light tank."
The lightly armored vehicle, which first saw action during the First Gulf War, is equipped with a 105 mm light gun and a 7.62 mm machine gun.
The wheeled design makes it fast — it can hit 50 mph, per Forbes — and highly maneuverable on smooth surfaces, while also requiring less maintenance than more heavily armored vehicles.
