Description

GarageImage 15cm sIG 33 B Sfl.jpg


The 15cm sIG 33 B Sfl is a rank I German tank destroyer with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.67 "Assault".

General info

Survivability and armour

The Sturmpanzer II does have enough armour to stop low BR tank rounds, however it should not be relied upon to stop High Velocity or High Penetration rounds, especially from other SPGs. It is an open topped vehicle, and since it has no machine guns, it is very vulnerable to air attack.

Despite having very little armor, it does have a lot of empty space in the tank to resist multiple penetrating hits before dying. However, it is hull-breakable against 75mm or larger guns with sufficient AP velocity or HEAT capability.

Mobility

The Sturmpanzer II can go up to 45kph, but due to a low-ish Power/Weight Ratio of 17.04hp/ton in AB and 9.74 hp/ton in RB, the practical top speed is significantly less. Reverse speed is decent, up to 8.4kph.

Armaments

Main armament

Main article: SIG 33 (150 mm)

The Sturmpanzer II mounts an S.I.G. 33 Infantry Support cannon, which can fire HEAT or HE rounds. The shell velocity is very slow (240m/s), so slow that it can be awkward to target moving targets or those at long ranges, especially with HE rounds. The calibre of the gun is 15 cm (150 mm/5.9 in). The Sturmpanzer does not have any other weapons.

The J.Gr.38 HE shell pens 65mm vs vertical armor and 60mm vs armor sloped back 60 degrees from vertical (30 degrees from horizontal), due to it having similar mechanics to Naval Guns of the same caliber. The 8.6kg explosive mass ensures that anything that gets penetrated is instantly knocked out or is so badly crippled that a followup shot is guaranteed.

The J.Gr.39 HI/A HEAT shell pens 185mm vs vertical armor, and still has a 4.16kg TNT equivalent, giving it effectively 40-45mm pen from HE splash on top of the HEAT superplastic copper jet penetration. In one of the minor updates of the game, 120mm & larger HEAT rounds were altered to act more like HE shells to benefit top tier - tanks such as the Sturmpanzer are unintentional beneficiaries of this change.

Usage in battles

The Sturmpanzer has no Air Defence weapons, so sticking with an SPAA tank at the back of the map is a good idea. If you want to close range brawl with low tier tanks, then sticking with another tank is a good idea since the long reload will cause you trouble if you get swarmed by lots of tanks. It has the capability to knock out much higher BR tank, so if you're uptiered, it's not the end of the world. However shoot before your opponent shoots, because if you come across a higher tier tank, you will be eliminated almost instantaneously. The best thing to do is to fire, then fall back to reload in a safe haven.

Pros and cons

Pros:

  • Tank can eliminate most modules or crew members of a tank in one well aimed shot, if not destroying it.
  • Can survive hits it will take from rank 1 tanks.
  • Can make a fair turn at speed when driving along.

Cons:

  • Reload means it is inadequate for close-range combat without allied support.
  • HE and HEAT are both stopped by various soft debris found on most maps such as fences, concrete blocks, brick walls, wood objects, etc.
  • Open-topped and very vulnerable to aircraft as a result.

History

Describe the history of the creation and combat usage of the aircraft 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 === Encyclopedia Info ===, also if applicable).

Media

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