| − | The '''15 cm sIG 33 auf Fahrgestell Panzerkampfwagen II (Sf)''', also known as the Sturmpanzer II Bison during World War II, is a German assault gun built primarily for infantry support and anti-fortification roles. Several prototypes were built, with the final one based on a standard Panzer II Ausf. B chassis. The chassis was extended by 60 cm, necessitating the addition of a sixth roadwheel, and widened by 32 cm to better fit the cannon while maintaining its low silhouette. A total of twelve units were built between December 1941 and January 1942. They were deployed to North Africa, where they formed schwere Infanteriegeschütz-Kompanien (mot.S.) 707 and 708 as close support mobile artillery. Both companies fought in Tunisia until the Axis surrendered in May 1943. | + | [[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]] |

| − | Introduced in [[Update 1.67 "Assault"]], the 15cm sIG 33 B Sfl is the largest calibre cannon available to German Army ground forces at rank I. The massive 15 cm calibre assault gun is capable of firing both high explosive (HE) and high explosive anti-tank (HEAT) rounds, which can completely cripple, if not destroy, any enemy tank it strikes. The vehicle, however, is completely exposed, leaving it extremely vulnerable to anything from machine gun fire to artillery strikes to aircraft strafing. Because of the low velocity and significant reload time, players should only fire when they are certain the shell will hit. Nonetheless, the 15cm sIG 33 B Sfl provided a highly unique and enjoyable experience in the German Army's beginner ranks.

| + | - Note: the HE on this is so powerful that it can even one-shot top rank tanks reliably, but due to the huge mobility disadvantage, this is not recommended unless you know exactly what you are getting yourself into. |
| | | | |
| − | * '''I.Gr.38 (HE):''' This round is extremely powerful, and can destroy pretty much every tank at the same battle rating as the {{PAGENAME}}. It requires only a hit on the tank, underneath it, or in close proximity to be effective. It completely ignores the armour of most tanks you will face, and is very good at destroying a tank with a single shot. It is likely that you will knock out several crew members and/or detonate their ammunition.
| + | The J.Gr.39 HI/A HEAT shell penetrates 185 mm against vertical armor and still has a 4.16 kg TNT equivalent of explosives behind it, giving it effectively 40-45 mm penetration from the explosion splash on top of the HEAT superplastic copper jet penetration. In one of the minor updates of the game, 120mm and larger HEAT rounds were altered to act more like HE shells to benefit top rank vehicles - tanks such as the Sturmpanzer are unintentional beneficiaries of this change. |
| − | | |
| − | * '''I.Gr.39 HI/A (HEAT):''' This round is effective, just as is the high-explosive round, but unless you are up-tiering the vehicle, the HEAT round is likely a worse choice. It has more penetration, but that penetration is unlikely to be useful at this BR. Plus, the HEAT does not have near as much post-penetration damage as the HE round, meaning you may waste 2 shots on 1 tank, whereas the HE round may have knocked it out with a single shot. As such, unless you are up-tiering the tank you will not need HEAT, and you should probably only take a few rounds (if any), just in case you run across something like a B1 Bis.
| |
| − | | |
| − | The I.Gr.38 HE shell penetrates 61 mm against all armour angles. The 8.6 kg TNT equivalent ensure that anything that gets penetrated is instantly knocked out or is so badly crippled that a follow-up shot is guaranteed. The HE shell is so powerful that it can even knock out top-tier tanks with a single shot reliably through overpressure, but due to the huge mobility disadvantage, this is not recommended unless you know exactly what you are getting yourself into.
| |
| − | | |
| − | The I.Gr.39 HI/A HEAT shell penetrates 185 mm against vertical armour and still has a 5.3 kg TNT equivalent of explosives behind it, giving it the possibility to inflict overpressure damage from the explosion splash on top of the HEAT superplastic copper jet penetration. | |

| − | The most recommended ammo loadout would probably either be 18 shells or 9 shells. If you expect a long lasting battle a full loadout should be preferred. 9 shells would be the choice if fast action combat is in sight. Taking only 9 shells removes all the ammo from the right side of the tank, reducing the risk of ammo rack detonation. Packing 9 shells is probably the most balanced ammunition loadout in terms of survivability and endurance, while packing a full loadout is suited for high/risk-high-reward gameplay.
| |
| − | | |
| − | At higher BRs 3.0 or more consider taking always a full loadout, because at this BR the chances of being destroyed with one hit is very high, leaving the pro of having more ammo (in theory more kills) outdoing the risk of an ammo rack explosion.

| − | The 15cm SIG can only played in mainly three ways:
| |
| − | | |
| − | The Sturmpanzer has no air defence weapons, therefore partnering with an SPAA tank at the back of the map is a viable option. For those operators who prefer to close-range brawl with other low-tier tanks, then sticking with another tank is a good idea, mainly due to the long reload time, allowing your partner tank to help fend off any enemy advancing tanks. It has the capability to knock out much higher battle rated tanks, so if you're uptiered, there is still a good chance of survival. However, it is imperative to get a shot off first, because if you come across a higher tier tank, there may not be a second chance. Stay on the move after firing, fall back to safety to reload and then re-engage.
| |
| − | | |
| − | Another tactic is to try facing down a street while partly undercover. The Sturmpanzer is a relatively small vehicle and many beginning players will not notice the tank, especially if only part of the vehicle is exposed. Patiently wait for an easy target to turn onto the street then fire before they realize where they are being fired from. It is critical to remember the shell drop of the tank cannon after being fired, compared to other tanks, the shell drop is significant over any distance. It is advisable to always fire just above where other tanks would typically target to allow for shell drop and hit the enemy vehicle where intended instead of lower than expected.
| |
| | | | |
| − | Due to the huge HE splash ability and sheer calibre of the gun, it can even be used to battle high-rank IFVs. It does the same thing to BMP-2s, M3 Bradleys, Warriors, Centauros, and many other vehicles. The HE splash, however, is strong enough that it can knock out light tanks such as the M41A1 Bulldog, any AMX-13 variation, Crusaders in lower ranks, and many others. Purposely up-tiering it can be a very effective way to earn Silver Lions with the "God Mode!" award - destroying an enemy vehicle 5.0 BR ranks higher (BR 6.0+) than you which nets 20,000 Silver Lions.
| + | 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. |
| − | | |
| − | ;Enemies worth noting
| |
| − | | |
| − | * [[B1 bis]]: This is one of the few tanks that you will face while playing at your original BR that you may struggle to destroy. These tanks are heavily armoured and much of their hulls can withstand a shot from your gun, even from the side. If you are facing one of these tanks, aim for the turret. The turret is one of the only places you can reliably do damage to the B1 bis, and you can often get a single-shot knock-out if you hit the turret. Note: The B1 bis looks extremely similar to its much more heavily armoured successor, the B1 ter, and it can be incredibly hard to tell which variety it is except at closer ranges. The B1 ter has thicker armour and so both HE and HEAT shells must be aimed much more carefully in order to cause damage.

| − | === Design ===
| |
| − | The Sturmpanzer I Bison was a self-propelled gun, consisting of a 150 mm sIG 33 heavy infantry gun mounted on top of a Panzer I chassis, together with a lightly armoured casemate to protect the gun servants. It was stop-gap vehicle used as an infantry support vehicle and showed its limits during the invasion of France and the Low Countries. The weight of the gun and the additional armour strongly hindered the mobility of the tank and caused premature mechanical wear. The gun installed very high on the chassis together with the casemate made the Sturmpanzer I a target of choice on the battlefield due to its very tall silhouette. The casemate did not protect all gun servants: the gunner and the commander were protected but loaders were extremely exposed as the casemate wasn't designed long enough to cover the rear of the vehicle. The extremely cramped layout of the vehicle made it impossible to stow ammunition: it had to be brought by a separate dedicated tank.
| |
| − | | |
| − | The need for the Sturmpanzer II was born early in 1941 when Rommel requested self-propelled guns to support his armoured divisions in North Africa.
| |
| − | This led the German Army to consider mounting the heavy gun sIG 33 on a vehicle chassis more fit to the task. The requirements for the new vehicle were to provide a less cramped layout for the gun and the crew to operate in optimal conditions, to give a silhouette as small as possible and to carry its own ammunition onboard, while maintaining the crew count, operational range and top speed of the previous Sturmpanzer.
| |
| − | | |
| − | === Development ===
| |
| − | After the battle of France, the German Army focused on equipping their tank divisions with Panzer III and IV. The Panzer II tanks were recycled into other vehicles to assume different combat roles: tank destroyers, self-propelled guns, training vehicles or reconnaissance tanks. The availability of the Panzer II made it a natural successor of the Panzer I for the project. The first prototype used the standard chassis of a Panzer II, which revealed a similarly cramped layout. To remedy the issue, the chassis was widened by 32 cm, lengthened by 60 cm and a 6th roadwheel added along with track links.
| |
| − | The new casemate was open-topped but effectively surrounded the crew compartment, with a reinforced frontal gun shield. The 15cm sIG 33 B Sfl also carried 30 rounds. The loaders were still slightly exposed to gun fire when fetching ammunition around the vehicle but the emphasis was put on keeping a silhouette as small as possible. The operational range was increased and the crew count of 4 maintained together with the top speed.
| |
| − | 12 vehicles were built in November and December 1941.
| |
| − | | |
| − | === Combat action ===
| |
| − | The 15cm sIG 33 B Sfl served in North Africa, in the German 707th and 708th Heavy Infantry Gun Companies Heavy Infantry Gun Company until their destruction or surrender in 1943.

Description
The 15cm sIG 33 B Sfl is a rank I German tank destroyer
with a battle rating of 1.0 (AB/RB/SB). It was introduced in Update 1.67 "Assault". BAsed on the Panzer 2 chasis, it was a 150 millimeter cannon and was used during the North African campaign.
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 being destroyed. 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 45 kph, but due to the low Power/Weight ratio of 17.04 hp/ton in AB and 9.74 hp/ton in RB, the practical top speed is significantly less. Reverse speed is decent, up to 8.4 kph.
Armaments
Main armament
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 penetrates 65 mm against vertical armour and 60 mm against armour sloped back 60 degrees from vertical (30 degrees from horizontal), due to it having similar mechanics to naval Guns of the same calibre. The 8.6 kg explosive mass ensures that anything that gets penetrated is instantly knocked out or is so badly crippled that a follow-up shot is guaranteed.
- Note: the HE on this is so powerful that it can even one-shot top rank tanks reliably, but due to the huge mobility disadvantage, this is not recommended unless you know exactly what you are getting yourself into.
The J.Gr.39 HI/A HEAT shell penetrates 185 mm against vertical armor and still has a 4.16 kg TNT equivalent of explosives behind it, giving it effectively 40-45 mm penetration from the explosion splash on top of the HEAT superplastic copper jet penetration. In one of the minor updates of the game, 120mm and larger HEAT rounds were altered to act more like HE shells to benefit top rank vehicles - 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.
