The Soviet Naval Infantry used ISU-152K self-propelled guns until their replacement by the 2S3 Akatsiya in the early 1980s.

They were introduced with the formation of a unique unit - The 55th Naval Infantry Division.

Originally created due to tensions between the USSR and China, it became the only Division in the Soviet Naval infantry, with an unusual composition of weapons and equipment.

By the mid-late 1980s, this division had begun a major reform process, the goal of which was to create a model division that would serve as a model for other divisions based on the brigades of the Baltic, Northern and Black Sea Fleets.

One of the main features was the presence of BMP-1/2 and even BMP-3! >;}

Thanks for watching and reading! ;]

There are some doubts about the ceramic filler of the late T-80U/UM/UD, since there is little photographic evidence of this (there are not enough photos with a section of the frontal part at storage/disposal bases)

Clarification - radiation line probably has a polymer formation meaning

(The increase in kinetic resistance of the upper frontal part without taking into account the ERA of the T-72B Obr.89 is 50mm higher from the kinetics in comparison with the T-72B Obr.85, however, it is still less protected in the turret compared to the T-80U Obr.87-89)

Otherwise, the illustration is largely true to reality.

P.S.

If you have any questions about the designation of some tank modifications, I will try to answer ;>

+Here are a number of photos from battalions of other divisions, which are described in the images

And in the last photo can see the design of the M1047 and LAV-25

P.S.

Perhaps soon I will collect a few more photos about the ISU-152K in Soviet Naval Infantry (55th Div) 1968 to the early 1980s.
