The Self Propelled 17pdr, Avenger (A30) is a rank III British tank destroyer with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update 1.55 "Royal Armour" along with the inital British Ground Forces tree. It is armed with the 17-pounder, with no secondary armament. It was based on a lengthened Cromwell hull from the A30 Challenger from World War II.

General info

Survivability and armour

Avenger is one of the most unexpected survivors on battlefields of War Thunder, both arcade and realistic mode.

All of this is due to fact that its crew sits in very specific places and the vehicle's armour doesn't have any small, weird weak spots. In fact, armour and overall module placement is so solid, it can sometimes hold off a SPAA attack, some bombs, and even a 75 mm from a M4A3E2 with some angling and range.

Even if shells penetrate (usually through the angled sides of the turret), usually only 2 crew members get knocked out.

The only strange weak spot the Avenger has is the windows on top of turret. While roof windows seem to be a flaw, as it creates potential for HE shells to simply fly inside of Avenger and decimate entire crew, in reality nobody uses those types of rounds at this BR. Even strafing planes have hard time hitting anything through those windows, and rather penetrate the roof directly, which is still a challenge.

Because of that, the windows instead give enemy APHE shells a high chance to bounce around and fly out of window without exploding inside of vehicle. In fact, this happens so often, a single Avenger can survive up to six direct shots while losing only gunner or loader, while vehicles like the Sherman Firefly would be destroyed in one hit by those.

Main Gun optics x3 x6
Comparable optics VFW

First tank in Tank Destroyer British tech line to have X6 scope. It will not get any better than this until rank VI, so get used to it - it will be the same across entire tech tree for a while with SPAA being the only exception.

As of rank III, this scope is slightly or moderately superior to most medium and heavy tanks, but do not expect to outsnipe German SPG as they have same optics or even better.

Usage in battles

The Avenger plays like an upgunned and a bit more sluggish Cromwell. There are two main play styles possible with this vehicle.

Close range flanker: The Avenger's mobility allows it to sneak up to the enemy's flank without too much problems. With its awesome gun depression, it can pop over a hill and shoot before engaging a "turn fight" (running around the enemy's tank too fast so he can't aim at you). Such manoeuvre has a greater chance of success on isolated enemies since you need to get at least 2 shots to destroy any tank you might encounter. This kind of strategy is great early in the game, to counter-capture a point by , for example, an enemy Hellcat that rushed it. A small note there: make sure to pre-aim in the general direction of your enemy since the turret turning rate is not so great.

Sniper: As said earlier, the Avenger's crazy depression angles and good gun, combined with its great mobility and good climbing characteristics makes it ideal for the sniper role. It's mobility allows the Avenger to get anywhere on the map, an intelligent pilot will avoid main roads where encountering enemies upfront is often a death sentence and prefer unexpected roads, surprising camping spots, your enemy must never know where to expect a shot from. When firing, make sure to change position every 2-3 shots (every time you destroy a tank). With a good mix of luck and skill, you can even find a good viewing point on the enemy's base pretty early in the game (even in AB !). Make sure sure to hide your turret top since HE and some APHE can detonate from the thin plate of your half open-topped turret, resulting in a crew knock out. One last thing to consider: the Avenger's functional elevation angle is lower than its characteristics says: the optics gets blinded in the last 1-2 degrees.

What's great with this vehicle is it can change role pretty fast in the game. A great way to use this vehicle at its plains potential is on a map like Mozdok or El Amalein. A good example of tactics is being flanker early game, then sniper to clear the next capture point and then flanker again to go get it (provided you do not get shut down).

  • Gun traverse speed is only subpar



The A30 Challenger tank was an improved variant of the Cromwell tank made to improve the firepower of the armoured brigades in the British Army. While equipped with the 17-pounder, the Challenger ran into issues with production and mechanical issues, along with design deficiencies that was much criticized by the crew that manned the tank. The Challenger had thin armour, had a tendency for track throwing, and had a high profile. However, it was praised for its speed, agility, and firepower with the 17-pounder gun. The Challenger was ordered in February 1943 for 200 vehicles, but the development of the Firefly from the Sherman tank proved much easier and cheaper than the Challenger and was thus cancelled.

The Avenger

An attempt to improve on the Challenger was the A30 SP Avenger, which used a different open-topped turret to save weight on the tank design. However, due to priorities on the Comet tank in the Vauxhall Motors plant, they were not being built until 1945 and weren't used until after the war in Europe is over. 250 unit were built and formed part of the British Army of the Rhine stationed in Germany after the war. They did not see any combat action during their service life.
