The '''{{specs|name}}''' is a Rank {{specs|rank}} Japanese medium tank {{Battle-rating|1}}. It was introduced along with the entire Japanese Ground Forces tree in [[Update_1.65_"Way_of_the_Samurai"|Update 1.65 "Way of the Samurai"]]. The prototype of the [[Type 74]], the STB-1 presents many features that would be in the final design.
 +
 
 +
The STB-1 is the first researchable tank in Japan's Ground Forces Rank V. Despite having considerable more armour than its comparable counterparts the Leopard 1 and Leopard A1A1, as well as comparable mobility, it is not recommended as a front-line tank like the 'Allied' counterparts. Instead, a cautious hit-and-run tactic like the Leopards should always be employed. Using the tank's [[hydropneumatic suspension]] correctly can help with the tank's depression, and in some cases, aid in survivability. Do note that the L7 on this tank reloads significantly longer than other L7-equipped tanks.
 +
 
 +
The STB-1 is unique among being one of the only Japanese tanks that can take a hit, like the Type 4 Chi-To Late and Type 5 Ho-Ri Production. It has thick frontal hull armour that can bounce shots effectively, but should not be relied on. The tank is quite fast and is further aided by the Hydropneumatic suspension, which allows this tank to manoeuvre the battlefield much like a Leopard, however the abundance of larger, more open maps at higher ranks means that getting from point A to B - and not getting shot - is not a simple as it sounds.

Description

The STB-2 is a Rank V Japanese medium tank with a battle rating of 8.3 (AB/RB/SB). It was introduced along with the entire Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". The prototype of the Type 74, the STB-1 presents many features that would be in the final design.

The STB-1 is the first researchable tank in Japan's Ground Forces Rank V. Despite having considerable more armour than its comparable counterparts the Leopard 1 and Leopard A1A1, as well as comparable mobility, it is not recommended as a front-line tank like the 'Allied' counterparts. Instead, a cautious hit-and-run tactic like the Leopards should always be employed. Using the tank's hydropneumatic suspension correctly can help with the tank's depression, and in some cases, aid in survivability. Do note that the L7 on this tank reloads significantly longer than other L7-equipped tanks.

The STB-1 is unique among being one of the only Japanese tanks that can take a hit, like the Type 4 Chi-To Late and Type 5 Ho-Ri Production. It has thick frontal hull armour that can bounce shots effectively, but should not be relied on. The tank is quite fast and is further aided by the Hydropneumatic suspension, which allows this tank to manoeuvre the battlefield much like a Leopard, however the abundance of larger, more open maps at higher ranks means that getting from point A to B - and not getting shot - is not a simple as it sounds.

Usage in the 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 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:

  • Highly mobile, comparable to the German Leopard I.
  • More armour than the German Leopard (around 100m hull and turret).
  • 105 mm L7 cannon found on other NATO tanks.
  • May bounce APHE shells.
  • Low profile.
  • Utilization of hydropneumatic suspension allows for various offensive and defensive options.
  • 12.7 mm Browning Machine Gun.

Cons:

  • Other areas are lightly armoured, vulnerable to high penetrating SPAA.
  • Reload and top speed slower than Leopard.
  • Small gun elevation angle.

History

The prototype for the Type 74. Known in Japanese as 74式戦車の試作車STB-1 (ななよんしきせんしゃのしさくしゃSTB-1). Created in September 1969 along with STB-2 in the STT program. Due to issues with cost effectiveness these two prototypes were not considered for the replacement of the Type 61. In a bid to reduce costs STB-3, STB-4, STB-5 and STB-6 were produced between April 1970 to December 1971. The final judgement for the STT program was held in November 1973 which lead the line to be completed in 1974. And, production started the following year in 1975 for the Type 74.

Media

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