The T-55M is essentially a modified Soviet T-55A, as such the armour and interior layout are identical to T-55A.

The T-55M has moderate frontal protection, with 100 mm plates for upper front plate (UFP) and lower front plate (LFP) placed at angles 59° and 56° respectively; effective thickness frontally comes up to ~180 mm and ~200 mm, respectively. At a perfect angle, the T-55M can bring its frontal effective thickness to ~200 mm and ~220 mm for the UFP and LFP, while having ~250 mm of protection at the angled sides. The additional 20 mm of protection will rarely provide any advantage at this BR as high-calibre APDS and APFSDS will have no difficulty penetrating your front plate.

As for the turret, the T-55M has slightly less protection than the T-62 and combined with a generally larger turret, it is easier for opponents to hit and penetrate the turret. The thinnest spots are right next to the cannon breech, at 200 mm, which rather slowly becomes over 300 mm when moving further away from the breech.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Large selection of ammunition

Cons:

• Reverse speed is awful
• Gun depression isn't great, it can have a hard time of depressing the gun on slopes

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
