The Merkava IID (also known as Mk.2D) is an advanced version of the standard Mk.2 Merkava, upgraded with a modular “Dor-Dalet” composite armor kit. It’s a tough and unyielding vehicle, featuring a number of battle-proven components such as its 105mm rifled cannon. The first version of the Merkava Mk.2 entered service in 1983 and the last vehicles were phased out in 2016 after thirty long years.
