In addition to its excellent gun, in patch 1.5.1 the STB-1 recieved the hydropneumatic suspension system along with buffs to the turret armouring, allowing it to take advantage of almost any hull-down position. The STB-1's excellent rate of fire combined with a reasonable 360 alpha damage allows the STB-1 to perma-track most opponents, allowing one to farm free damage at little to no risk to themselves. While the STB-1 no longer has the highest DPM the tier 10 medium tanks, having given up that spot to the K-91, it still remains a significant threat on the battlefield, with a blistering rate of fire rivalling that of the 100mm armed tier 10 Soviet mediums. It can reliably hull down unlike its predecessors due to a much needed increase in turret armor. The STB-1 is similar to the previous tanks in the line, with the exception that it now has much better turret armor than the tanks before it.

Forward top speed is average at 50 km/h.

Crew and internal modules are very prone to injury/critical damage.Not counting the turret face, the rest of the tank is very poorly armored.Great acceleration and agility, excellent reverse speed.Good gun depression which can be further improved with hydraulic suspensions.One of the highest DPM values in the game for a medium tank.
