The MBK pr.186 is a rank IV Soviet armoured gun boat with a battle rating of 3.3 (AB/RB/SB). It was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game.
Survivability and armour
The MBK pr. 186 has signifigantly more armor than it's predecessors all-around, and can take a fair beating as a result. The middle portion of this ship has 30mm of rolled homogeneous armor, while the front and back have protection of 8-12mm. This defence makes death by machine gun fire much less likely, almost a relic of the past. However, this additional armor makes this ship much heavier, and detrimentally effects the speed, as elaborated in the next section.
The MBK pr. 186 has an abysmal top speed of 26.3 km/h with stock equipment, and around 33 km/h fully upgraded. The turning speed is also terrible, and it will take more than a dozen seconds to completely turn around. Due to this fact, the MBK pr. 186 must be played with very strategically chosen movements, as becoming exposed with no quick way out is one of the most common ways to be destroyed in this ship.
The vessel responds quickly to steering inputs, so evading torpedoes is easier than might be expected from the slow speed.
The MBK pr. 186 has two T-34-85 turrets as its main guns. These guns fare fairly well against medium sized ships due to their reasonable caliber, and can sometimes hull-break small ships, although small enough ships are seldomly encountered at this BR. Up until this point, HE shells were the indisputably best shell for naval combat due to the lack of armor anywhere. However, at this BR you will fight destroyers, which have a fair amount of armor and may require APHE shells to fight.
In addition to the two 85mm cannons, there is a 37mm autocannon, the same model as the one used on the Pr.1124 (1945) and the BMO as well as the MPK-163. This gun is a fairly good secondary gun due to its caliber and good rate-of-fire, and can tackle both small to medium sized ships and most air targets.
The MBK pr. 186 has two twin-mount 12.7mm DShK turrets that are mounted on both sides of the command bridge at the center of the ship. As such, only one turret can engage a target at a time due to the interrupted arc of fire unless the target is directly in front or behind the ship. This is not the most desirable positioning but it will work most of the time deterring air attacks, with the help of the 37mm autocannon.
Usage in battles
As mentioned above, the MBK pr. 186 has decent armor but terrible mobility. This means it is not optimized for quick attacks or ambushes, but must rather be used for tactical attacks, as it is difficult to escape from an engagement once it is made. Additionally, this boat has an inordinately large repair cost, sometimes in excess of 20,000 SL, so this boat must be played very, very carefully in order to maintain a desirable outcome.

Pros and cons
- 2 x 85mm provide plenty of firepower to destroy boats
- Secondary and AA armament is on a par with the main armament of most other PT boats
- Armour provides significant protection against machine-guns and small caliber cannon HE ammunition
- Expensive repair cost
Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an 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

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
