Inside of the Israeli tech tree the Merkava mk2b at 9.3 GRB lacks a .50 caliber machine gun.
compared to the Merkava mk1b, the mk2 has a better transmission that provides a 23km/h reverse speed rather than the mk1s 11km/h reverse speed.
The Merkava MK1 has 3x (7.62mm machine guns) and 1x (12.7mm M2HB MG)
The Merkava MK2 has 3x (7.62mm machine guns) and no 12.7mm M2HB.
The only difference between the MK1 & MK2 is the upgraded transmission and 12.7mm M2HB MG.
I could see that the lack of a 12.7mm mg would be made up for by having the better transmission. however, the Merkava MK2B in the American tech tree has the upgraded transmission, a 12.7mm MG and an additional layer of composite screen atop the turret. Aside from those details the 2 tanks are identical statistically. this means that the Israeli Merkava mk2 is the only Merkava in the entire game without a 12.7mm MG.

The Merkava MK2B inside of the Israeli tech tree should receive the 12.7mm M2HB MG in comparison to its counterparts. The .50 Cals were nerfed not to long ago as well…
