The OTO R3 T20 FA-HS is a rank III Italian self-propelled anti-aircraft gun with a battle rating of 4.0 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".

General info

Survivability and armour

The R3 T20 FA-HS has light armour able to protect it against .50 cal machine guns from front and medium-calibre machine guns from the sides. Any autocannon or tank cannon is able to shred through this armour. The R3 has an internal layout with the crew separated apart, allowing it to survive damage from non-explosive shot.


The R3 T20 FA-HS is very mobile, able to outmanuver most tanks of its rank and is reliant in this to stay alive.


Main armament

Main article: Oerlikon KAD (20 mm)

The 20 mm Oerlikon is able to fight both aircraft as well as lightly armoured targets from the front.

Upgraded, the gun has access to the 20mm rounds able to penetrate up to 50mm of armour, enabling the tank to shread any tanks that exposes its side to this vehicle. Some heavier tanks are still too heavily armoured from the sides for the gun to penetrate, but these generally don't show up unless you are uptiered.

Usage in battles

The R3 is designated as an SPAA, and performs in this role extremely effectively. The autocannon has a rapid rate of fire and high velocity, allowing the R3 to tear aircraft to shreds. With accurate fire, a short burst will obliterate most aircraft in very little time. When the skies are clear and there are no more planes to shoot down, the R3 becomes a highly flexible vehicle, being able to zip around the map at high speed performing various tasks. Early game it makes an excellent recon vehicle, being able to capture points, oversee the battlefield and destroy enemy vehicles.

With over 50mm of penetration and its exceptional speed, the R3 makes short work of British and American medium tanks from the side and will shred light tanks and other SPAA. The R3 does not have the penetration to handle heavy tanks and so tanks like the KV-1 should be avoided.

Pros and cons


  • With the best belt, it is possible to penetrate many tanks, including the sides of the Sherman and many low-rank British and Soviet tanks
  • Twin-axis stabilizer
  • Immensely fast, often the first vehicle on the cap
  • Seemingly invincible wheels
  • Front plate has armour thickness sufficient to deflect most machine gun rounds, and even certain light cannon rounds
  • Immense fire rate, a 20 mm firing at 996 rounds per minute can do quite a number on low rank aircraft, often snapping wings off IL-2s
  • Very little lead is required to score hits on planes
  • Large ammo pool, with no need to reload
  • Somehow capable of righting itself even when flipped on its roof
  • By aiming backwards and down and firing while driving, the recoil can be used as a turbo to propel the light vehicle forward
  • Can bounce rounds with its sloped frontal armour
  • Can swim


  • Very little side and roof armour, can be very easily dispatched by anything larger than a 7.7 mm, in most cases can be destroyed by M2s mounted on both tanks and planes
  • Engine is very fragile and susceptible to machine gun fire from behind, concentrated 7.7 mm fire can actually destroy the engine
  • Sub-par reverse gear compared with its forward gear
  • Tips over very often, especially when firing
  • As with many wheeled vehicles, awful in the sand
  • Due to its size, can be very easily crushed
  • Hard collisions damage modules and can often injure or incapacitate the crew
  • The gun is unable to fully elevate
  • A widely hated vehicle by enemy players, you will be a primary target for both aircraft and ground vehicles
  • 12.7mm machine gun fire can devastate vehicle
  • Recoil will cause the suspension to sway, meaning that a continuous burst will have to be adjusted while firing
  • Only 600 rounds loaded into a single belt with no spare, meaning all 600 rounds have to be expended before a resupply is possible


Describe the history of the creation and combat usage of the ground vehicle 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 main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.


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