The Merkava, which is means Chariot in Hebrew, is the main battle tank of Israel Defense Forces.
Four main types of the Merkava series have been deployed since 1978.
The Merkava Mark IV, the series' latest edition, is the more advanced version of the Merkava Mark III. It came into service with the Israel Defense Forces in 2004.
Until now, a total of 360 Merkava Mark IV vehicles have been built, with an additional 300 in production.
Slightly larger than the Mark III, the new vehicle is one of the best shielded tanks in the world.
