In 2007, IBD Deisenroth Engineering presented the Leopard 2 Evolution. Compared to the Leopard 2A4, this tank offered enhanced firepower, protection, and situational awareness without requiring a new turret, unlike the Leopard 2A5. Additionally, all new components could be installed independently, allowing potential customers to select only the elements they deemed necessary. Over the years, the modernization package was improved further and gained customers. In 2013, Indonesia ordered 103 vehicles, 61 of which were to be delivered as Leopard 2RIs. Based on the 2010 Leopard 2 Revolution prototype, the modernization included AMAP armor modules on the hull and turret, an electric turret drive, an FCS adapted for new ammunition, and an air conditioning system. All vehicles were delivered between 2016 and 2017 and remain in service to this day. They have not seen combat.

The Indonesian Leopard 2RI was introduced in Update 2.57 "Heavy Cavalry" as part of the Japanese ground research tree. It is a versatile combat vehicle with no significant strengths or weaknesses. Its armament enables it to destroy any opponent head-on, and its FCS makes it effective at any range and time of day. Its mobility enables it to attack at the forefront and swiftly capture points. However, its armor is mainly designed to protect against chemical rounds, and enemy kinetic rounds are likely to penetrate it. The large crew and spacious internal layout give the tank a good chance of surviving the initial penetration, but the ability to return fire afterwards is not guaranteed.
