The Leopard 2 is a 3rd generation main battle tank originally developed by Krauss-Maffei in the 1970s for the West German army. The tank first entered service in 1979 and succeeded the earlier Leopard 1 as the main battle tank of the German Army. It is armed with a 120 mm smoothbore cannon, and is powered by a V-12 twin-turbo diesel engine. Various versions have served in the armed forces of Germany and 13 other European countries, as well as several non-European nations, including Canada, Chile, Indonesia and Singapore. The Leopard 2 was used in Kosovo with the German Army, and has seen action in Afghanistan with the Dutch, Danish and Canadian contributions to the International Security Assistance Force, as well as seeing action in Syria with the Turkish Armed Forces.

There are two main development batches of the tank: the original models up to Leopard 2A4, which have vertically faced turret armour, and the improved batch, namely the Leopard 2A5 and newer versions, which have angled arrow-shaped turret appliqué armour together with other improvements. All models feature digital fire control systems with laser rangefinders, a fully stabilised main gun and coaxial machine gun, and advanced night vision and sighting equipment (first vehicles used a low-light level TV system or LLLTV; thermal imaging was introduced later on). The tank has the ability to engage moving targets while moving over rough terrain.

The Singapore Army acquired 96 ex-German Leopard 2A4s, including 30 spare tanks. A number were upgraded with additional AMAP composite armour in 2010 by IBD Deisenroth and ST Kinetics and renamed Leopard 2SG in October 2010. By 2019, it was reported that Singapore had taken delivery of 158 Leopard 2A4s and 45 Leopard 2A7s.However, the Singapore Government has denied that it received deliveries of Leopard 2A7s.
