Production began in April 1943, with a planned production run of over 800 vehicles.

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)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 25 mm (78°) Upper glacis 50 mm (40°) Lower glacis - top 35 mm (50°) Lower glacis - bottom |

Notes:
- Suspension wheels are 15 mm thick while tracks are 20 mm thick and bogies 10 mm thick.

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
