GarageImage UDES 33.jpg

The Underlagsgrupp Direkt Eld Stridsfordon 33 (shortened to UDES 33, literally Ground Group Direct Fire Combat Vehicle 33) is a rank V Swedish tank destroyer with a battle rating of 7.7 (AB/RB/SB). It was introduced in Update 1.97 "Viking Fury".

General info

Survivability and armour

The thickest plate on the UDES 33 is 18.5 mm, and all armour plates are rolled homogeneous steel. Survivability is very poor. A single shot to the hull can instantly knock out at least two of the four crew members (however, hitting all four is far more common). Furthermore, the gunner is completely exposed from the waist up.

Main armament

Main article: Rbs 55

The Rbs 55 is a potent ATGM at the battle rating, however the reload leaves something to be desired. The time it takes to reload the ATGM will allow many of your foes to replace their crew members before you are ready to fire again, so this must be kept in mind. Often times it is best to retreat back into cover if the missile only knocks out an opponent's gunner, rather than dealing sufficient damage to their gun breech or barrel. Additionally, the UDES 33 can only carry a maximum of 10 missiles, so they must be used sparingly. Taking a full ammo load is recommended. The speed at which the missile launcher can be aimed at a target is decent, however do not expect to be able to quickly return fire at an opponent should you manage to survive a shot from them. The launcher is restricted in horizontal movement to approximately the 3 and 9 o'clock positions.

Usage in battles

The UDES 33 performs best when using natural terrain cover, as it cannot take very much punishment. It is advisable to sit behind the primary lines of the allied team, and pick enemies off that expose themselves in the distance. Be wary of IFVs and SPAAs (or any vehicle with a high rate of fire), as well as the machine guns mounted on any vehicle, as the gunner is exposed entirely and the hull armor is very weak. Notable opponents include the M3 Bradley, M163, Gepard, BMP-2, ZSU-57-2, ZSU-23-4, Warrior, Falcon, WZ305, SIDAM 25, and AMX-30 DCA. The UDES 33 can perform at battle ratings 8.0-8.7, but when at 6.7-7.3, the angle of armour on many German tanks should be considered before engaging.

Pros and cons


  • Rather agile for its tonnage, and when upgraded is surprisingly quick and nimble, easily allowing for moving from cover to cover
  • Low profile, not a very large target and very noticeable when standing still
  • ATGM penetration proves adequate
  • Great gun depression, allowing the vehicle to fire from behind cover by simply exposing the ATGM launcher


  • Gunner is largely exposed; his whole torso is above the turret ring, leaving him vulnerable to MG fire, shrapnel, and aircraft guns
  • Somewhat long reload time


Describe the history of the creation and combat usage of the vehicle 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 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></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
