The 2S1 has as much armour as light tanks such as the PT-76B, light enough armour to be penetrated by the American .50 cal, so this tank is not the most protected.

Armour type:

• Rolled homogeneous armour

In RB, the mobility of the 2S1 is tolerable. It reaches a higher speed quicker than most tanks in its BR due to it being built on a light chassis but bleeds speed quickly when turning. Turning the 2S1 from a stand still is incredibly slow and driving forward or reversing first is suggested to gain the needed momentum to turn.

In AB, the 2S1 moves like a light tank, accelerates quickly and has a high speed with good turning with some speed bleeding.

Usage in battles

The 2S1's biggest weakness is high fire rate guns such as AA and other howitzers as both can eviscerate your vehicle very quickly. In RB, it is suggested to use your howitzer as it was intended: long distance destruction. Use your speed to get to vantage points. The 2S1 does not have much gun depression so you will need to use the environment for your own concealment and gun shooting angles.

In AB, it is quite the opposite, since there is no point in concealment in arcade your best being in the second line behind heavy tanks and mediums picking off enemy heavy's and mediums.

Pros and cons

Pros:

• Fairly mobile
• HE rounds have enough filler to destroy any target
• Great elevation angles

Cons:

• Long profile
• Very weak armour
• Crew placement not ideal
• Extremely slow turret traverse
• Slow turn speed from standstill

History

The development of a new self-propelled gun for the Soviet army was based on the well-proven D-30 howitzer and the chassis of the MT-LB multipurpose amphibious towing vehicle. The D-30 towed howitzer was modified to be placed in the SPG turret, the MT-LB chassis was lengthened by adding a wheel pair to improve the driving performance and increase the room of the fighting compartment. After a year of testing, the vehicle was put into service in September 1970 under the designation 2S1 Gvozdika. Serial production of the SPG continued until 1991. The vehicle was produced in the USSR, as well as in Bulgaria and Poland under license. The 2S1 is still in service with the armies of many countries of the world.
