The Leopard 2A4 is the most produced variant of the German Leopard 2 main battle tank. On March 2, 1979, the Netherlands ordered 445 Leopard 2A4NLs to replace its outdated AMX-13 and Centurion tanks. They differed from the German version in that they had a new smoke launch system, FN MAG machine guns, upgraded radios, a periscopic driver night vision device, and minor turret modifications. By January 1993, the government had decided to sell 115 tanks to Austria and upgrade the remaining 330 to the Leopard 2A5NL standard.

During their service, some vehicles were assigned to the Opleidings- en Trainingscommando (OTCo), the Education and Training Command. The OTCo traces its origins to November 1, 1969, when its predecessor, the Command for Training of the Royal Netherlands Army (COKL), was founded. The COKL oversaw all military training in the country. Following budget reductions and a decrease in personnel after the end of the Cold War, it was reorganized in 2001 into the OTCo and took on responsibility for soldier education.

The Dutch Leopard 2 (OTCo) was introduced in Update 2.47 "Leviathans" as a part of the French ground research tree. It is a versatile tank with high mobility, excellent firepower, and good armor. However, only 16 rounds are protected by blow-out panels, and the armor has several weak points. Compared to the Leopard 2A4NL, it features a removable camouflage kit made of mesh nets and tarp sheets, as well as a different camouflage scheme.
