Biblical sources cite Solomon having as many as 1,400 chariots, with special centers being constructed to house them.
Since its adoption, it has become the backbone of the Israel Defense Forces (IDF) armored forces.
A major concern for the Israeli government was its reliance on Western hardware.

The IDF responded quickly, opting to produce its own tank.
An initial prototype was completed in 1974, but the IDFs modern chariot wasnt publicly disclosed until 1977.
Two years later, it entered service with the IDFs armored forces.

That really shouldnt be seen as a design flaw, however.
All tanks are the result of a compromise between firepower, protection and mobility.
That resulted in a small cross-section, which made it less of a target.

This was meant to counter HEAT (high explosive anti-tank) rounds should any strike the turret.
The round would detonate on hitting the chains instead of the turret ring.
The Mk IIA was the first updated model, entering service in April 1983.

It featured minor adjustments, including increased armor, yet employing the same 105mm gun and 60mm mortar.
It was followed by the Mk IIB, which offered thermal optics and enhancements to the fire control system.
The turret was also redesigned to allow for easier movement for the crew.

Two years later, the first Mk IV battalion became fully operational.
With its introduction, the IDF began to retire its older U.S.-made M60A1 series tanks.
That provided the Merkava a bit more pep.

Once an incoming projectile was detected, the Trophy system fired a shotgun-jot down blast to neutralize the threat.
However, as Israel hasnt widely exported its armored chariots, only a few are now in museums.
