Description
The M-51 (W) had the same role as the normal M-51 and the only difference was the hull: instead of the M4A1 hull, it was built using the M4A3 and M4A4 chassis. Considered to be the most advanced version of the Sherman ever produced, the M-51 featured a 105 mm gun, an improved engine, a new turret, and access to a powerful HEAT shell. Developed based on the M-50, it was Israel's primary tank against Soviet-made T-55s and T-62s during the Yom Kippur War. In this conflict, neither the Centurions nor Patton tanks were capable of consistently penetrating the armour of the new Soviet designs, and while the M-51 was unreliable, slow, and had little to no protection, its armament was the most capable of all tanks in service with the IDF. Despite being obsolete, 180 were built, and had decent results during the Six Day War of 1967 and the Yom Kippur War, even against the most modern Soviet designs.
It was introduced in Update "Winged Lions". The M-51 (W) has two differences compared to the regular M-51 found in the tech tree. The first is that it uses the M4A3 chassis instead of the M4A1. While the difference in armour is not enough to make a difference, the shape of the armour makes it possible for the M-51 (W) to bounce some shells off the front if it's lucky and the enemy tank makes a bad shot. The second is that the pintle-mounted machine gun has been upgraded from a 7.62 mm LMG to a 12.7 mm HMG, allowing it to more easily deal with lightly armoured vehicles and break down obstructions. Its HEAT shell has 400 mm of penetration at max, and it's capable of dealing with any enemy at its BR, even against the Maus. However it has very poor mobility (off-road and reverse speed), its armour is non-existent, and if it's penetrated, surviving is unlikely, and also does not have access to a stabilizer like previous Shermans. Since it relies on its firepower, it's recommended to stay back in comfortable positions behind the protection of your team, and if you are going to be at the frontline, stay close to your teammates.
General info
Survivability and armour
While the Sherman had decent armour for its time, its armour will be penetrated by most enemies it will face at this rank. That's why you should adopt a playstyle similar to the Pz.IV F2: rely on your gun and mobility and keep distance between you and the enemy vehicles.
Armour type:
- Rolled homogeneous armour (Hull)
- Cast homogeneous armour (Turret, Transmission area, Cupola, MG port)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 63.5 mm (48-57°) Upper glacis 25.4 mm (spherical) MG port 63.5-107.9 mm (cylindrical) Transmission housing 63.5 mm (53°) Lower glacis |
38.1 mm | 38.1 mm (21°) Upper plate 38.1 mm (14-44°) Lower glacis |
63.5 mm (23-42°) Front glacis 19.5 mm Crew compartment 19.5 mm (8-24°) Engine compartment 9.5 mm Vents |
| Turret | 51 mm (13°) Turret front 100 mm Gun mantlet |
51 mm (0-13°) | 51 mm (55-64°) | 25.4 mm |
| Cupola | 63.5 mm (Conical) | 25.4 mm | ||
Notes:
- Suspension wheels are 15 mm thick, tracks are 20 mm thick, and torsion bars are 10 mm thick.
Mobility
The M-51 (W)'s mobility is respectable. While the vehicle's top speed and acceleration lags behind contemporary vehicles, it can still allow the vehicle to perform in a somewhat-satisfactory manner as long as it is not expected to win races.
Reverse speed remains a common problem in the M4 Sherman platform, with the M-51 (W) only able to reverse at -5 km/h. So when firing from a position, be aware of the reverse speed in order to afford the M-51 (W) enough time to duck behind cover before enemy tanks can attack back, or instead push forward into cover to make the most of the forward speed available.

Armaments
Main armament
The most iconic feature of the M-51 (W) is its large 105 mm M-51 gun, a variant of the French CN-105-F1 cannon for their AMX-30 tanks. The gun's claim to fame is the OCC 105 F1 HEAT shell that allows the M-51 (W) tank to penetrate up to 400 mm of armour from any distance.

Notes:
- Shells are modeled individually and disappear after having been shot or loaded.
- Rack 3 is a first stage ammo rack. It totals 8 shells and gets filled first when loading up the tank.
- This rack is also emptied early: the rack depletion order at full capacity is: 3 - 1 - 2.
- Simply not firing when the gun is loaded will move ammo from racks 1 and 2 into rack 3. Firing will interrupt the restocking of the ready rack.
Machine guns
Like most other M4 Sherman platforms, the M-51 (W) contains a standard coaxial machine gun, and a pintle-mounted heavy machine gun. Both remain useful for harassing low-flying aircraft and defeating lightly-armoured vehicles that may not warrant a 105 mm round.

Usage in battles
The M-51 (W) is a relatively complex tank to play as it has characteristics that serve the tank well, yet just as many characteristics that are a detriment to the tank's ability to perform its roles.
The M-51 (W)'s weaknesses should be recognized first. Its survivability after a first hit is poor as the M-51 (W) is built on a M4A3 hull with no substantial armour improvement. As such the front armour array has poor protection against the kind of armaments the tank is expected to go against. What is also not helping is the tank's relatively slow speed, which makes travelling from cover to cover a longer chore. Combined with the tank's large profile with the Sherman hull body and the long 105 mm gun, it would be relatively easy to spot an exposed M-51 (W) from a distance and destroy it. Another drawback is the ammunition composition available, with only chemical-energy shells (HEAT, HE, Smoke) available. This means that the gunner must ensure there is no light cover or foliage that would detonate the shell before it can reach its target.
However, noteworthy characteristics of the M-51 (W) for its favor is, of course, the armament. The large 105 mm gun is capable of delivering a HEAT shell a distance away. This allows the tank to attack targets of its choosing without regards to penetration drop-off with distance. The turret also has a reasonable traverse rate and elevation ranges, allowing for quick target responses and use in different terrain and hills.
With these considerations in mind, the M-51 (W) would excel in the "sniper tank" or "ambusher" role. Play these roles in the defense as the M-51 (W) does not have great mobility to get to certain locations before the enemy will. Instead, allow the enemy to roll into the M-51 (W)'s field of fire closer in the friendly team side. Set up the M-51 (W) in areas covering known enemy advances towards the objectives, their transit in between objectives, or their movements into friendly front-lines after capturing the objectives. Good fire zones can be established with the 105 mm's HEAT round, using the generous gun depression angles for hull-down locations to use terrain as cover. Alternatively, one may also exploit the M-51 (W)'s height to find rock formations low enough to cover the hull, but also expose the turret to allow the M-51 (W) to fire from behind cover before withdrawing to reload so the enemy doesn't hit and penetrate the turret.
Alternatively, the M-51 (W) may be used as a "brawler" role by getting up close to the enemy. This role is not well-advised due to the M-51 (W)'s weak armour, slow mobility, and average reload speed. However, the tank's gun and turret traverse rate allow the M-51 (W) to be rather responsive in close-quarter combat. Perform this roles with allies, especially those in more dangerous tanks like heavy tanks, in order to reduce the likelihood that the M-51 (W) is the first to be targeted during these attacks. If the M-51 (W) is caught isolated, it will very quickly be torn to pieces. Use the available smoke grenades to make a retreat if needed.
Pros and cons
Pros:
- Impressive firepower thanks to HEAT's 400 mm penetration
- Great long range cannon since HEAT retains penetration regardless of distance
- Wide FOV in the gunner's sight
- Quick turret traverse
- 4 turret-mounted smoke grenades
Cons:
- Massive gun wobbling: the gun is not stabilised and bounces a lot
- Poor top speed and acceleration
- With its poor armour and massive gun, close quarters combat is not recommended
- Cramped turret due to the large breech
- Fires only early HEAT shells, which are prone to ricochets and inconsistent damage
- The HEAT shell has low muzzle velocity and unreliable post-penetration damage, aiming at ammunition and crew positions is necessary
- The large muzzle brake catches a lot of shells, destroying the gun
History
Upon its establishment in 1948, the Israeli Defense Force (IDF) was desperate to set up an armoured corps in order to contend with the multi-pronged Arab invasion. World War II surplus early-model M4 Sherman tanks, many of them already rendered combat-ineffective, were purchased from any European source that would provide them. A significant Israeli repair effort finally managed to get most of these tanks working in time to defeat the invading armoured battalions, ultimately winning the war. The basic M4 remained the IDF's primary tank for more than half a decade, precisely because it was considered obsolete everywhere else and could therefore be purchased en-masse at scrapyard prices. During the early 1950s it was slowly replaced with more advanced Sherman models, whenever those could be acquired.
Unfortunately for the IDF, this situation could not continue for long. Newfound cooperation between the Arab states and the Soviet Union resulted in an influx of T-34-85s into the region, whose armour was very difficult to penetrate using the M4's original 75 mm M3 cannon. It was obvious that the Shermans would need to be replaced in order to keep up with the arms race. Initially, the IDF considered purchasing the new AMX-13 from France (which was rapidly becoming Israel's primary weapon supplier), but the tank was determined to be too lightly armoured. Instead, a number of French CN-75-50 cannons (also known as the SA50 L/57) were purchased separately and installed into the turrets of existing M4A4 Shermans. This resulted in the Sherman M-50, known abroad as the "Super Sherman" and in War Thunder as the M4A4 (SA50).
The M-50s proved highly effective during the Sinai War of 1956, but the lessons of that war resulted in the Soviets flooding the region - particularly Egypt and Syria - with the newest T-54/55, armed with a 100 mm cannon and carrying more modern curved armour. Once again, new French AMX-30s were rejected as replacements for the M-50, but their new CN-105-F1 105 mm cannons proved quite suitable for the IDF's purposes. The Israelis modified these cannons to their own specifications, slightly reducing barrel length and muzzle velocity as well as fitting the cannon with a brand new muzzle brake. This modified cannon would be installed on an M4A1 Sherman hull fitted with a T23 turret (the turret originally used for 76 mm Sherman variants). The tank was then fitted with a number of additional modernization features, including infrared spotlights and a better fire control system.
This new model was dubbed the Sherman M-51, of which 180 were constructed in total. They first saw action during the Six-Day War of 1967, where they often outmatched Syrian and Egyptian T-55s. In combat in the West Bank during that war, the M-51 exceeded expectations even further by thoroughly defeating Jordanian M48 Pattons - very similar to the model that was in the process of replacing the M-51 in IDF service at the time. Despite becoming effectively obsolete by the 1970s, the M-51s were called back into action in 1973 during the desperate situation of the Yom Kippur War, and reportedly managed to hold their own even against late-model T-62 tanks.
All in all, the M-51 is considered to be the last and most advanced version of the Sherman ever produced.
