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.
Armour type:
- Rolled homogeneous armour (Hull, Turret roof)
- Cast homogeneous armour (Turret, Gun mantlet)

A weak spot of the T-55M's is a shot through the upper front plate, as while more protected then other T-55s, is still weak. A good shot here can knock out three of the four crew members easily.
Pros and cons
Pros:
- Large selection of ammunition
- APFSDS can pen pretty much every tank at its BR
- Stabilizer
- Decent speed & acceleration, even when not fully modified.
Cons:
- Reverse speed is awful
- Gun depression isn't great, it can have a hard time of depressing the gun on slopes
History
Between 1960 and 1970, Finland purchased 74 T-55As from the Soviet Union to bolster the numbers of their tank core and complement the T-54s. At the turn of 1980-1990, all T-55As were modernized to the new standard, adding the M suffix to their designation. In early 2000s, most of the T-55Ms were retired with last 9 T-55Ms being used for mine clearance. By the end of 2022, all T-55Ms were officially retired from the service.
