The {{PAGENAME}} has the same protection as the 75/34 M43 but sits at a higher battle rating, reducing its effectiveness. While still effective against earlier guns, it will begin to encounter enemies with weapons that can easily defeat its armour, such as the American 76 mm M1 or British QF 17-pounder. The upper glacis will be easily penetrated by these guns, and the superstructure, while more heavily protected, will similarly be easily penetrated, and due to the confined nature of the fighting compartment likely result in destruction of the vehicle. The lower glacis is easily penetrated at closer ranges, however the transmission will typically absorb most of the damage. Angling can be used to increase the effectiveness of the superstructure, however exposed cheeks become a weak spot for enemies to target. Using an obstacle to hide the vehicles cheeks while angling is important to maintain effective armour.

'''Armour type:'''
−
-->
 
−
The Semovente 75/46 retains the improved armour of its 4.0 predecessor, with a 25mm slightly-angled frontal plate sitting in front of a flat 75mm plate and a driver's hatch on the left-hand side adding an additional 25mm of protection. This allows the Semovente's frontal armour to effectively provide up to 145mm of penetration when properly angled, or 170mm over the driver's hatch. For this reason. players should always look to angle the tanks' left side toward the enemy to allow the hatch to bounce shots more effectively.
 
  
−
Despite this however, the vehicles' armour scheme does contain a number of weak spots. Angling to maximise the protection of the front and side armour exposes an 85mm flat target around the vehicles headlamps. In addition to this, the lower glacis offers only 50mm of angled armour plates, although shots that penetrate this area will often be absorbed by the transmission, saving the tank at the cost of its mobility
+
* Rolled homogeneous armour (hull, casemate)
 +
* Cast homogeneous armour (gun mantlet)
  
−
As a result, the Semoventes' armour can provide very effective protection against same or lower-rank tanks when properly angled. Ideally, the vehicle will look to use its extremely effective high-velocity gun to engage targets from a distance, where its small frontal profile and strong frontal armour make it difficult to penetrate. Enemy players will often fail to identify the tanks weak-spots and simply fire into the flat frontal plate, allowing the Semovente to bounce rounds effectively.

The armour becomes much less effective in a full up-tier however, with Allied guns such as the British 17-pdr, US 76mm M1 and Soviet 85mm D-5T being able to reliably penetrate the vehicle at close range even when angled. The tanks' small size and cramped crew compartments also means that APHE shells offer little hope of survival should they get through its armour.

−
As with most tank-destroyers, the vehicles' side and rear armour do little to protect it in case of a flank, and players should always look to keep their nose pointed toward the enemy.
+
The {{PAGENAME}} has reasonable mobility for a tank destroyer, being able to hit and maintain around 37 km/h when driving off-road on level ground. The vehicle has an average reverse speed, reaching -6 km/h in its single gear. Despite its lack of neutral steering, the {{PAGENAME}} can traverse its hull reasonably quickly from a full stop, greatly helping to overcome its lack of a turret.

The small calibre of the Breda Mod. 38 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.

The Semovente is usually most effective when remaining at a distance, where its powerful gun and strong frontal armour can do their best work. A player should ideally look to exploit the tanks' small frontal profile and reasonable mobility to get into strong position's on the enemies' flank. The 75mm gun's high velocity, good reload and post-penetration effectiveness make it ideal for attacking enemy tanks from the side, where it can easily penetrate their side armour even in a full up-tier. This normally represents the safest way to play the vehicle.  
+
The Semovente's M43 75/46 lacks any kind of turret, which has its benefits and its disavantages. At a distance, the Semovente's M43 75/46 limited traverse is less a handicap and makes it harder for the weak spots of the vehicle to be hit. The vehicle's primary advantages include its low profile and powerful gun which can easily defeat most enemies it will encounter at range while remaining a relatively obscured target. Using the vehicle's gun depression and low profile to take advantage of terrain, such as a rock, building, or hill, will make it harder to hit, increasing its survivability.  Unlike other Self propelled guns, the Semovente's M43 75/46 does not have unreliable armour, this allows the vehicle to play a more aggressive role.
  
−
Players can be considerably more aggressive when top-rank however. Most adversaries at 4.3 or below will struggle to stop the Semoventes' gun with their frontal armour, and the vehicles' fast traverse time and low profile can allow it to quickly take out an unaware enemy, even in close quarters.  
+
Against weaker enemies, such as vehicles equipped with the American 75 mm M3, it can more aggressively expose itself, but care must be taken in case the M43's mobility is impaired or against vehicles with more powerful guns. If you play too close to the frontline, most tanks will be capable of disabling you due to your weak sides. If you are exposed any enemy can simpily flank you and easy take you out of the match without too much effort.
  
−
The most dangerous adversaries for the Semovente are either heavy tanks with extremely thick and angled armour, or vehicles with powerful APCBC shells that can defeat its frontal plate. [[M4A3E2|Sherman Jumbos]] have the frontal armour to stop the Semoventes' gun, with their only weakspot being their machine gun port or their turret ring, both of which represent very small targets. A Jumbo in a hull-down position represents an incredibly difficult target for the Semovente, although its short-barrelled gun will have trouble penetrating the Italian tanks' frontal plate.
+
In terms of armament the 75 mm OTO 75/43 mod.40 gun can defeat most enemies at its ranking, with only some heavier tanks able to effectively resist the gun, such as the [[Churchill VII]] or the uparmoured [[KV-1 (ZiS-5)]]. In this case, waiting for the enemy to expose a vulnerable area of their armour or identifying them for allies to target is ideal. Attempting to flank or more aggressively approach should be avoided. If facing higher ranked vehicles, more caution must be used, as there will be more enemies able to resist your fire while being able to defeat your own armour. Knowledge of appropriate weak spots can help defeating vehicles like the [[M4A3E2]] Jumbo or [[IS-1]] tanks, but these may be unreliable, meaning a more cautious approach is safer.
  
−
Heavy Soviet tanks such as the KV-1 and the rarer IS-1 are also tough opponents for the Semovente, with the KV best shot through the turret cheeks or the machine-gun port when angled. While the IS-1 has a far better gun than either the KV-1 or the Jumbo, its vulnerable turret ring can allow the Semovente to bypass its extremely thick frontal armour.
+
Mobility wise, it's not the greatest but it will be adeqaute enough that you won't usually be lagging behind your comrades in a match unless the map features a lot of muddy terrain or water. Its good to note that the Semovente M43 75/46 has weak sides, if you expose your tank to enemy vehicles you won't have enough time to react. So it is overall vital that you do not get flanked and you always have friendly tanks to aid you whenever you are in trouble.

A German-designed variant of the Semovente 105/25, with improved armor and using the german Pak 40 anti-tank gun in place of the original howitzer.<ref name="LeartiglieriedelRegioEsercito">Filippo Cappellano. ''Le artiglierie del Regio Esercito'' Italy, Storia Militare, 1998</ref> Due to the low production output of the italian licensed version of the gun, only eleven were built, while other were outfitted with the available italian 75/34 gun. They only saw service with German forces in Italy in late 1944 and 1945.
+
The story of the Semovente M43 75/46 began during the late stages of the second world war. In mid-1942, the Italian Army put out a set of requirements for a new vehicle that could double up as both an infantry support vehicle as well as a tank destroyer, depending on the situation. In response to this, Fiat-Ansaldo and OTO Melara both began developing together prototypes around these requirements in parallel. The two competing designs primarily differed in the chassis choice. OTO picked the newer chassis of the P40 heavy tank whilst Fiat-Ansaldo chose to opt for a newer and larger version of the chassis already in production for their Semovente M42. This decision allowed Fiat-Ansaldo to complete their prototype much sooner. In February 1943, the Semovente [[105/25 M43]] was presented to military officials and was soon afterwards ordered into production, following successful trials. Production began in April 1943, with a planned production run of over 800 vehicles. However, with Italy's industry at this late stage of the war being severely crippled, production was slow and reaching such high production goals was more than unlikely. Just prior to the signing of the armistice in September, the 30th vehicle rolled off the assembly line. The Semovente 105/25 M43 proved itself in combat during the defence of Rome, where the SPGs successfully engaged German forces trying to retake the city. The {{PAGENAME}} is a further variant which was developed from the Italian Semovente 105/25. The main changes included improved armour to the vehicle, which greatly increased its surviability against allied tanks. Another change included the adoption of the German Pak 40 anti-tank gun in place of the original 105 mm howitzer.<ref name="LeartiglieriedelRegioEsercito">Filippo Cappellano.

Description

The Semovente 75/46 M43 is a rank III Italian tank destroyer with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".

The 75/46 M43 has the same protection as the 75/34 M43 but sits at a higher battle rating, reducing its effectiveness. While still effective against earlier guns, it will begin to encounter enemies with weapons that can easily defeat its armour, such as the American 76 mm M1 or British QF 17-pounder. The upper glacis will be easily penetrated by these guns, and the superstructure, while more heavily protected, will similarly be easily penetrated, and due to the confined nature of the fighting compartment likely result in destruction of the vehicle. The lower glacis is easily penetrated at closer ranges, however the transmission will typically absorb most of the damage. Angling can be used to increase the effectiveness of the superstructure, however exposed cheeks become a weak spot for enemies to target. Using an obstacle to hide the vehicles cheeks while angling is important to maintain effective armour.

Armour type:

  • Rolled homogeneous armour (hull, casemate)
  • Cast homogeneous armour (gun mantlet)

The 75/46 M43 has reasonable mobility for a tank destroyer, being able to hit and maintain around 37 km/h when driving off-road on level ground. The vehicle has an average reverse speed, reaching -6 km/h in its single gear. Despite its lack of neutral steering, the 75/46 M43 can traverse its hull reasonably quickly from a full stop, greatly helping to overcome its lack of a turret.

The small calibre of the Breda Mod. 38 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help or to mow down minor obstacles blocking your line of sight.

Usage in battles

The Semovente's M43 75/46 lacks any kind of turret, which has its benefits and its disavantages. At a distance, the Semovente's M43 75/46 limited traverse is less a handicap and makes it harder for the weak spots of the vehicle to be hit. The vehicle's primary advantages include its low profile and powerful gun which can easily defeat most enemies it will encounter at range while remaining a relatively obscured target. Using the vehicle's gun depression and low profile to take advantage of terrain, such as a rock, building, or hill, will make it harder to hit, increasing its survivability. Unlike other Self propelled guns, the Semovente's M43 75/46 does not have unreliable armour, this allows the vehicle to play a more aggressive role.

Against weaker enemies, such as vehicles equipped with the American 75 mm M3, it can more aggressively expose itself, but care must be taken in case the M43's mobility is impaired or against vehicles with more powerful guns. If you play too close to the frontline, most tanks will be capable of disabling you due to your weak sides. If you are exposed any enemy can simpily flank you and easy take you out of the match without too much effort.

In terms of armament the 75 mm OTO 75/43 mod.40 gun can defeat most enemies at its ranking, with only some heavier tanks able to effectively resist the gun, such as the Churchill VII or the uparmoured KV-1 (ZiS-5). In this case, waiting for the enemy to expose a vulnerable area of their armour or identifying them for allies to target is ideal. Attempting to flank or more aggressively approach should be avoided. If facing higher ranked vehicles, more caution must be used, as there will be more enemies able to resist your fire while being able to defeat your own armour. Knowledge of appropriate weak spots can help defeating vehicles like the M4A3E2 Jumbo or IS-1 tanks, but these may be unreliable, meaning a more cautious approach is safer.

Mobility wise, it's not the greatest but it will be adeqaute enough that you won't usually be lagging behind your comrades in a match unless the map features a lot of muddy terrain or water. Its good to note that the Semovente M43 75/46 has weak sides, if you expose your tank to enemy vehicles you won't have enough time to react. So it is overall vital that you do not get flanked and you always have friendly tanks to aid you whenever you are in trouble.

Pros and cons

Pros:

  • Effective gun penetration, damage, and reload
  • Small frontal profile makes the tank easy to conceal and difficult to hit
  • High and low gun depression, can be used to crest over hills while only exposing the more heavily armoured superstructure
  • Decent mobility and good hull traverse
  • Mounted machine gun can be used to fire in a frontal arc

Cons:

  • Generally ineffective armour against similarly tiered vehicles
  • Lack of turret and thin side armour are vulnerable to being flanked
  • Lacks an APCR shell for more heavily armoured targets
  • Confined interior and only 3 crew lessens survivability on penetration
  • No turret

History

Main article: History of the 105/25 M43

The story of the Semovente M43 75/46 began during the late stages of the second world war. In mid-1942, the Italian Army put out a set of requirements for a new vehicle that could double up as both an infantry support vehicle as well as a tank destroyer, depending on the situation. In response to this, Fiat-Ansaldo and OTO Melara both began developing together prototypes around these requirements in parallel. The two competing designs primarily differed in the chassis choice. OTO picked the newer chassis of the P40 heavy tank whilst Fiat-Ansaldo chose to opt for a newer and larger version of the chassis already in production for their Semovente M42. This decision allowed Fiat-Ansaldo to complete their prototype much sooner. In February 1943, the Semovente 105/25 M43 was presented to military officials and was soon afterwards ordered into production, following successful trials. Production began in April 1943, with a planned production run of over 800 vehicles. However, with Italy's industry at this late stage of the war being severely crippled, production was slow and reaching such high production goals was more than unlikely. Just prior to the signing of the armistice in September, the 30th vehicle rolled off the assembly line. The Semovente 105/25 M43 proved itself in combat during the defence of Rome, where the SPGs successfully engaged German forces trying to retake the city. The 75/46 M43 is a further variant which was developed from the Italian Semovente 105/25. The main changes included improved armour to the vehicle, which greatly increased its surviability against allied tanks. Another change included the adoption of the German Pak 40 anti-tank gun in place of the original 105 mm howitzer.[1] Due end stages of the war, and the consistant bombardment of Italian factories and supply lines, it lead to the low production of the Italian-licensed version of the cannon. In the end only eleven 75/46 M43 were fully built, while others were outfitted with the available Italian 75 mm Ansaldo L/34 gun, leading to the production of the 75/34 M43 tank destroyer.
