== Description ==

'''Bretagne''' was a French super-dreadnought, lead ship of [[Bretagne (Family)|her class]], launched in April 1913. Due to the constraints of the French shipyards, her length and displacement remained almost unchanged compared to her predecessors of the [[Courbet (Family)|Courbet class]]. During World War One, she was delegated to blockading the deployment of German and Austro-Hungarian submarines. During the interwar period, Bretagne underwent several very extensive modernizations, including updating fire control systems, replacing an outdated mast with a tripod, and strengthening anti-air defence.

With the outbreak of World War Two, the battleship was based in Toulon and participated in the naval blockade of Germany. In March 1940, she transported part of France's gold reserves to Halifax. At the time of the Invasion of France, she was stationed in Mers-el-Kébir. After the surrender of France, the British command decided to launch an attack on Mers-el-Kebir in order to prevent French ships from falling into German hands. On July 3, during Operation Catapult, the fleet stationed in harbour came under fire from the battleships HMS Valiant and HMS Resolution and the battlecruiser [[HMS Hood]] along with escort vessels. Bretagne received several hits from 381 mm shells, leading to an explosion and sinking which killed 1,012 crew members. In 1942, attempts were made to raise the battleship's hull for cutting, but they were stopped after an explosion occurred on board. In 1952, the hull was finally raised and by 1954 cut for scrap.

The Bretagne was introduced in [[Update "Alpha Strike"]] in her 1925 refit. She plays like a typical WW1-era dreadnought, being best used in a second line, picking off targets with her multiple large-calibre guns. Her mediocre armour, little mobility, and next to no anti-air defenses make it difficult for her to compete for capture points or slug out against vessels at higher BRs.

== History ==

By 1910, the previously competitive French Navy was considerably behind major naval powers such as Britain, Germany & the USA in terms of capital ships, having not yet laid down a single dreadnought type warship whilst the Kaiserliche Marine had built 8 dreadnoughts and a battlecruiser, the United States Navy had built 6 dreadnoughts and the Royal Navy had built 10 dreadnoughts and 5 battlecruisers, and that's ignoring the additional capital ships the nations also had under construction at the time. Even the Imperial Russian Navy had four of its first dreadnought class under construction at the time and Brazil owned two dreadnoughts which Britain had finished construction of that same year. It was only in late 1910 that the first of the 4 French Courbet class dreadnoughts had been laid down, meanwhile other major powers were continually producing and planning yet more capital ships.

In an attempt to reverse France's current naval inferiority, the government authorised an ambitious naval program in March 1912, calling for a force of 28 modern battleships to be completed within the next 8 years, starting with the new Bretagne class of 3 super-dreadnoughts, all laid down that same year.
[[File:BretagneClassProvence.jpg|thumb|Provence, of the Bretagne class, sailing during the First World War]]

To compete with the designs of contemporary battleships, the Bretagne class required 340 mm guns over the prior 305 mm of the Courbet class, but within a hull based on that of the Courbet so that it would still fit France's limited dockyards, necessitating 5 turrets rather than the 6 of the Courbet. However, the Bretagne placed all of its main turrets on the centreline, retaining the 10 gun broadside of the Courbet, which used two wing-turrets.

The three ships of the class were completed just prior to the outbreak of the First World War, though a fourth ship ordered by Greece was never completed. The ships spent the majority of the war in port while guarding the Adriatic from potential Austro-Hungarian incursions, as well as being used to intimidate Greece, which was leaning toward supporting Germany. Through the interwar years, the three ships received sporadic refits and conducted training cruises. During the Spanish Civil War, Bretagne & Provence joined non-intervention patrols off the Spanish coast.

Following the start of the Second World War, the ships initially didn't see any action outside of escorting several convoys. However, after the Fall of France, Force H of the Royal Navy accosted the majority of the French Navy in the harbour of Mers-el-Kébir in July 1940, delivering an ultimatum which suggested various ways for the French fleet to be interned by or integrated with the Royal Navy to prevent the Axis from having any chance of seizing the ships and overwhelming the British Mediterranean Fleet. Failure to comply with the ultimatum would result in Force H attempting to destroy the French Fleet in the port, which included Bretagne and Provence.

After several hours of negotiations, no agreement was reached and the warships of Force H initiated hostilities upon the French fleet. Within minutes, Bretagne was struck by two 381 mm shells from the third salvo of HMS Hood, HMS Resolution & HMS Valiant, one blasting a hole in the hull with a fiery explosion, causing flooding, and the other destroying the centre engine room. 7 minutes later, another two 381 mm shells hit, which was shortly followed by a catastrophic ammunition detonation that rocked the ship, causing it to roll over and sink. Meanwhile, Provence had begun returning fire on Force H about 90 seconds after the British opened fire, but scored no hits and was then subsequently hit by several 381 mm shells, igniting blazing fires onboard and tearing open the hull, allowing vast quantities of water to flood in, eventually sinking the ship to the bottom of the harbour.
[[File:BretagneMersElKebir.jpg|thumb|Bretagne on fire and flooding after being struck by two 381mm shells, shortly prior to detonation]]

Following the attack, though Bretagne was a lost cause, Provence was raised from the seabed. The ship was somewhat repaired and transferred to Toulon, where it stayed until being scuttled in 1942 to keep the Germans from using it.

Meanwhile, whilst all that had been going on, Lorraine had been interned in Alexandria since the Fall of France. In 1942, the crew of the ship decided to join the navy of Free France and the ship served as a training vessel though 1943. The ship then received a major refit before participating in Operation Dragoon of 1944 as an artillery support ship during the landings. The last action of the ship during war was the bombardment of German forts in northern France in March 1945.

Following the war, the Lorraine became a gunnery training ship and then a barracks ship before being decommissioned in 1953 and sold to scrappers. What was left of Bretagne was raised and scrapped in 1952, while the hulk of Provence was raised and scrapped in 1949.

== Description ==

The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} American heavy tank {{Battle-rating}}. It was one of the first American tanks to be released with the American ground tree in [[Update 1.45 "Steel Generals"]]. A premium version of the [[M4A3E2|M4A3E2 Jumbo]]. As a side note, the nickname "Jumbo" was likely never used during WWII, as there is no record of it. However, its use both on the Wiki and in-game is still prevalent.

The "Cobra King" is in many aspects the same vehicle as the regular M4A3E2. There are however a few notable cosmetic differences:

* a shade of green on the vehicle's stock livery different from the standard US olive-drab green, with a more pronounced green colour than the subdued mix with brown,
* the large white marking "First in Bastogne" present on the hull's left side, boasting about the tank's actual achievement in the US Third Army in World War II, and a bit lower on the hull sides will a decal with the name "Cobra King",
* and finally, the presence on the rear of the vehicle of kit, canvas, gear, tracks, and fuel tanks, which are absent on the regular M4A3E2.

The Jumbo's armour is nothing to underestimate. It can bounce most shells at point blank range when angled more than 30 degrees. And the turret is well armoured from all sides, too. One of the weak spots is around the machine gun port. This tank is used as a breakthrough tank to attack fortified enemy positions due to its thick armour. As such it allows players to get close to most enemy tanks and attack them from the sides, or force them to retreat. On the downside, the gun is wimpy without M61 shot and even then it still bounces more often than not. Best to take a bit more ammo than normal to compensate for all the shots that will bounce.

=== Survivability and armour ===
{{Specs-Tank-Armour}}

The "Cobra King" still features the double layered front armour giving the vehicle its distinctive 101.6 mm total front armour. The transmission housing is also considerably beefier too from the addition of armour at the area as well. The front of the T23-style turret is also distinctive with the very blocky gun mantlet and circular barrel shroud around the rather underwhelming 75 mm gun barrel.

The sides and suspension look like the usual game with the M4 Sherman series, but with minor differences. The flat side armour of the hull, instead of 38.1 mm thick is now 76.2 mm thick for much stronger side protection. However, the lower side hull around the bogie suspension area is still only 38.1 mm thick, vulnerable to most regular anti-tank weapons. Another minor difference is the tracks, the T48 rubber chevron tracks are equipped with extended end connectors in an effort to improve ground pressure performance for the additional weight of the armour.

'''Armour type:'''

* Rolled homogeneous armour (Front, Side, Rear, Roof)
* Cast homogeneous armour (Turret, Transmission area)

'''Notes:'''

* Suspension wheels are 15 mm thick, the bogies are 10 mm thick, and tracks are 17 mm thick.
* Belly armour is 25.4 mm thick.
* Hull underside right above the tracks are 9.5 mm thick.
* Gun breech is 300 mm thick in structural steel.

The M4A3E2 Jumbo presents very little frontal weak spots in an engagement. It is best to try and force the Jumbo to try and angle his vehicle towards the player or his allies. An angle more than 30 degrees can expose the much weaker lower side hull armour in the suspension that is only 38.1 mm thick. With a powerful enough gun, a round can penetrate this area and damage the crew, or even set off the ammunition all cluttered up on the bottom of the tank.

If a frontal engagement is unavoidable and is unfortunately armed with guns unable to penetrate through the front glacis, there are only two areas that are viable. First is the machine gun port, which is one of the areas that is not layered with the extra 38.1 mm added on top of the base armour. Guns like the Panzer IV 75 mm KwK 40 guns that are unable to cleave through the front glacis can push their luck in this area, with small "sweet spots" the round can pass through. Another way to attack the M4A3E2 in this scenario is exploiting a shot-trap in the gun mantlet. The small corner flaps on the bottom corners of the gun mantlet have a tendency to deflect rounds downwards onto the 19.5 mm hull roof armour. While this will be left to the ricochet chances, it is still possible and can be used if no other scenarios are favourable.

== Usage in battles ==


The Cobra King is best in assaulting enemy positions with allies. Its great mobility for a heavy tank, especially with its armour, makes it a vehicle able to charge into battle with confidence. It can act as a bullet magnet against enemy tanks more worried about the Cobra King, diverting fire that would have been directed more vulnerable teammates. Though the 75 mm gun's AP performance is not suited to the type of enemies expected at the BR, it can still harass enemies and the gun is lethal enough that enemies will be forced to show their front armour towards the Jumbo else a 75 mm penetrates their side armour. Their focus on the Jumbo can allow allies to move around and eliminate them. During all this, take care not to over-angle and show the lower side armour too much as this will allow vehicles to penetrate through down there and damage modules, even the ammunition storage if they are lucky.

Another role the Cobra King is good at is as a flanker. Due to its great mobility as a heavy tank, the Cobra King can manoeuvre like a medium tank around the battlefield. This is also beneficial to the 75 mm gun as it would permit the Cobra King a chance to attack the weaker side armours of enemy vehicles. Once flanking around and finding a prime position in a firing angle right into an enemy chokepoint, minimize exposure to anything but the front armour and the Cobra King can remain a formidable obstacle to all opponents. Take care not to be outflanked by enemy players aware of the Cobra King's position.

As the Cobra King has a slightly higher battle rating than the other M4 Shermans, it can be up-tiered against tanks such as the [[Tiger H1]] and the [[Panther D]], meaning its M61 round will be almost harmless. For this reason, it is advisable to take the T45 APCR ammo into battle, at least enough to take on the armoured targets the Cobra King will face.

The Soviet 85 mm can be a threat, so caution is advised when going up against tanks armed with the 85 mm, such as the [[T-34-85]], [[SU-85]], and [[IS-1]]. The [[Jagdpanzer 38(t)]] and [[Jagdpanzer IV]] can be tricky when facing off against them. Their frontal armour is too thick and sloped for the 75 mm M3 gun to have any effect on it. For these two targets, it is advised to target their tracks and transmission and then flank for a side shot, where the armour is much weaker. Finally, the Sturer Emil wields a 128 mm that can penetrate the front plate of the Cobra King, so caution is advised against those as well.

=== Pros and cons ===


'''Pros:'''

* Excellent frontal armour
* Very strong turret armour from all sides, very good at hull down position
* Good mobility for a heavy tank
* Good acceleration
* APCR shot has a high penetration power
* High rate of fire for the 75 mm gun
* Excellent gun depression
* Equipped with gun stabilizer, making it more accurate at moving and when preparing a shot after moving

'''Cons:'''

* 75 mm M3 gun lacks penetration against most tanks frontally
* APCR shot has poor post-penetration damage
* The frontal armour still presents several weak spots enemies can easily exploit
* Side and rear armour are pretty weak and limit angling tactics
* Low top speed
* Reverse speed is poor

== History ==


===Development===
Even before the invasion of Normandy, the Allied commanders had to figure out a method in order to breach heavily-defended fortification lines such as the Siegfried Line blocking the path from France to Germany. One of the solutions was the implementation of "assault tanks" that would enter enemy territory and root out the enemy fortifications. The initial plan was for the production of the [[M26|M26 Pershing]] tanks to fulfil this role, but setbacks in its development caused the M26 deployment to be delayed until 1945. A quick solution had to be made to fill this "assault tank" role for the invasion of Europe in 1944.

The US Ordnance Department then took their abundant [[M4|M4 Shermans]] in stock and fixed them up for the new role they've been assigned. Although keeping the same engine, the armour was upped from around 76.2 mm initial thickness to 102 mm and angled at 47 degrees from vertical. This angle would influence later Sherman designs such as the M4A3 by changing the original 56 degrees angled glacis with protruding crew hatches to 47 degrees angled glacis without any protrusion from the crew hatches. This modified M4 Sherman's armour when angled would then be 150 mm line-of-sight (LOS) thick and 180 mm effective. The side armour was also increased to 76.2 mm thick and the turret was redesigned to provide more protection. These modified Shermans were designated as the [[M4A3E2]] by the Ordnance Department, whereas the nickname "Jumbo" was likely a post-war invention. At the end of the modifications, the Sherman "Jumbo" now weighed about 42 tons and moved at a lower speed of 22 miles per hour. A drawback to the increased weight of the Sherman is that the Vertical Volute Suspension System (VVSS) from the Sherman was unable to take the weight easily, so extra care was taken by the crew members to not break the suspension.

In March of 1944, the US Army ordered 254 of these vehicles to be delivered for use in European Operations. Intended to assault the Normandy Beachhead, it was deployed in Normandy after D-Day to assist the infantry push through German defences. The M4A3E2 originally came with the 75 mm cannon to support infantry with its better HE shells compared to the planned 76 mm instalment, but the 76 mm was installed later in the campaign and called the [[M4A3E2 (76) W]] Jumbo.

===Combat usage===
The M4A3E2s was well-liked by the crew and commanders due to its protection value. Despite the weight difference and strain on the suspension, it performed reliably and could absorb damage that would otherwise destroy regular Shermans. Later in the war, when the quantity of the M4 Sherman "Jumbos" were unable to meet the demand, George S. Patton ordered the existing M4 Shermans to weld on armour plates scavenged from knocked out tanks to makeshift "on-the-field" Jumbos. This caused the newer Shermans such as the [[M4A3 (76) W|M4A3 (76) W HVSS]] to have the same protection by welding metal onto the hull. One of the Jumbo's notable participation in the war was in Patton's Third Army where it spearheaded the assault of Bastogne to relieve the pinned down 101st Paratroopers. The '''M4A3E2 "Cobra King"''' was the tank Lt Charles P. Boggess commanded to lead elements of Patton's Third Army into Bastogne on December 25, 1944. The 101st was finally relieved and reconnected with the Third Army on December 27. "Cobra King", however, was knocked out sometime during the fighting (maybe during the Hammelburg Raid) and had its interior destroyed by an internal fire. When the tank's remnants were identified in 2008, it was shipped back to the United States to Fort Knox at the Patton museum to be restored by Len Dyer, director of the Patton Museum and the soon-to-be National Armor and Cavalry Museum. After two years of restoration work, the tank was put into the display at Fort Benning as a dedication to the Charlie Company of the 4th Armored Division's 37th Tank Battalion.

The Washington Post, WP Company, 3 Aug. 2017, [https://www.washingtonpost.com/news/retropolis/wp/2017/08/03/a-battered-world-war-ii-hero-of-bastogne-gets-a-new-home-and-museum-built-around-it/?utm_term=.7d7604b9ecab Website]</ref>

When the war in the European Theater ended, the M4A3E2s were then placed stateside for the preparation for the invasion of the Japanese Home Islands. However, this was never to be fulfilled as Japan surrendered to the United States in September 1945. The M4A3E2 Shermans proved to be a very effective stop-gap solution until heavier armoured tanks such as the Pershing could come into play. In 1948, about 96 Sherman Jumbos still remained in US inventory.

=== In-game description ===
Preparations for the invasion of Europe saw a heavily armoured assault tank designated M4A3E2 (76)W designed using the M4A3 base. In March 1944 the Armed Forces Committee approved a program refitting 254 tanks, some of which were equipped with 76 mm cannons. Their armour was strengthened by stacking 38 mm armour plates welded together on the front and sides of the hull. As a result, the frontal armour reached a thickness of 102 mm to go along with the 76 mm on the sides.

The transmission was protected with a 140 mm cast cover, while the rest of the hull was not modified. The new T23 cast turret had walls 152 mm thick and was special in that it did not have a hatch from which to fire a personal weapon. The 178 mm mantlet was mounted with a 76 mm M1A1C cannon, while ammunition was stored in wet stowage.

The thicker armour pushed the tank's weight to 38 tons, simultaneously lowering its top speed to 35 km/h.

The exact number of M4A3E2 tanks refitted with 76 mm M1A1C cannons was never ascertained.

The tanks were very popular as column leads, given the fact that German antitank guns could not penetrate their frontal armour.
