Je ne veux pas engager de polémique ni mettre en doute ce que tu dis mais d'après ce site (http://www.waronline.org/en/IDF/arms/merkava.htm)
Le Merkava Mk IID se nomme aussi Merkava siman 2 Bet dor Dalet.
Voici le passage qui en parle:
Merkava siman 2 Bet dor Dalet
(Merkava mk.2B with fourth generation armor) - the modernization of existing Merkava mk.2B,
the main difference is additional armor plates on the chassis and the turret, the so-called "fourth
generation armor" (dor - generation in Hebrew). Not to confuse with 4th generation tank,
this only means that Merkava mk.1 had first generation armor, mk.2 - second, and mk.3 - third.
The add-on armor plates are fourth generation.
Sometimes this tank is also called Merkava Mk.2D
The visual difference is the additional armor modules on the turret sides that are curved downwards,
as opposed to Merkava mk.3 dor Dalet modules which extend sideways. The tank also has easily
noticeable additional armor plates on the sides of the chassis above the sideskirts, and on the front
left side above the driver's position.
