== Description ==
''Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.''

=== Vehicles equipped with this weapon ===


* {{Specs-Link|t_129_atak}}
* {{Specs-Link|a_129_cbt}}

== General info ==
''Tell us about the tactical and technical characteristics of the cannon or machine gun.''

=== Available ammunition ===
''Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).''

=== Comparison with analogues ===
''Give a comparative description of cannons/machine guns that have firepower equal to this weapon.''

== Usage in battles ==
''Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.''

=== Pros and cons ===
''Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.''

'''Cons:'''

== History ==
''Examine the history of the creation and combat usage of the weapon 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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Weapon-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>.''

== Media ==
''Excellent additions to the article would be video guides, screenshots from the game, and photos.''

== See also ==
''Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:''
* ''reference to the article about the variant of the cannon/machine gun;''
* ''references to approximate analogues by other nations and research trees.''

== External links ==
''Paste links to sources and external resources, such as:''
* ''topic on the official game forum;''
* ''other literature.''

-The TM 197B is a turret made by OTO-Merla to mount the M197 20mm Vulcan on the A-129 Mangusta (Mongoose) attack helicopters. The turret was built by Leonardo-Finmeccanica (now Leonardo S.p.A.) the parent company of Augusta, the manufacturer of the A-129 CBT. The TM 197B was built to be used to replace 12.7 mm machine gun pods used on early models of the Mangusta, but the company also advertises the turret can be used on other models of military helicopters even if they weren’t originally designed for combat. Proving both air-to-ground and close-range air-to-air combat, the turret offers a lighter weight and low profile than other mounts for the M197 cannon. The turret has ±100° azimuth coverage and -50°/+20° elevation coverage that can be controlled from a helmet and display sight system that follows the movement of the crew or by the main sight of the computer system. The TM 197B operates at speeds of up to 140 knots and can keep tracking during manoeuvres. As a safety measure against power failure for either the helicopter or the turret, the gun is locked in a forward position.
