Description
The G6 is a rank IV British tank destroyer with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update "Danger Zone".
Often referred to as the "G6 Rhino" or simply the "Rhino", it entered service and serial production with the South African Army in 1988. It was a self-propelled version of the G5 Howitzer series. It has been operated not only by the South African Army, but also Oman and the United Arab Emirates, a combined total of just over 100 exports. It has seen combat in the South African Border War as well as the ongoing Yemeni Civil War.
In War Thunder, it has situational utility as a support vehicle, specialising in long-range support by exploiting positional advantages earlier than other vehicles. The firepower of the G6 is exceptional, with one of the most potent high explosive rounds in the game, capable of taking out almost any target in just a single hit. Despite having excellent speed, it performs quite poorly in the mobility department. It has low off-road speeds, extremely poor acceleration, and - like all wheeled vehicles - has a large turning circle which is further exacerbated by the extreme size of the vehicle. This size makes it vulnerable to spotting and identification, so stealth is generally hard to pull off in this SPG. Compounding this issue, it has next-to-no armour to speak of, just barely protecting it against rifle calibre fire. High calibre machine guns, autocannons, and artillery are consequentially extremely dangerous for this vehicle.
General info
Survivability and armour
The armour of the G6 is negligible. It is no thicker than 30 mm, with the overwhelming majority of the vehicle being protected by 10-15 mm of rolled homogeneous armour (RHA). This only protects against rifle calibre machineguns. Autocannons and high calibre machineguns will tear the G6 apart. Despite this, APHE rounds fired by Soviet tanks may pass through doing minimal damage, due to a higher fuse threshold than that of the armour. Furthermore, the thin armour reduces spall from incoming solid-shot projectiles like APDS or AP rounds, which can lead to increased survivability when penetrated. The crew of 6 also means that it is difficult to whittle down the number of crew members, granting extra survivability. 8 x 155 mm smoke grenade launchers provide adequate cover in emergencies.

Mobility
On paper, it would seem that the G6 would have excellent mobility, with a top speed exceeding 53 mph (86 km/h). However, this is somewhat deceiving as in reality the mobility of the G6 is very limited. It not only has very poor acceleration, but as a wheeled vehicle it severely lags behind with regards to off-road performance. Adding to this, its immense size and length means that it has a very large turning radius, and it has no neutral steering or ability to turn on the spot. It also lacks adequate breaking speed, taking a long period to come to a stop, and longer still to stabilise the primary armament.
In summary, the vehicle is fast on roads, however it lacks in off-road capability, acceleration, deceleration, responsiveness to input, and turning area.

Armaments
Main armament
The primary - and only - armament of the G6 is the 155 mm G6 L/45 cannon. It has exceptional explosive filler in both its M1 HE and M1 PF HE shells. Despite having low penetration at only 63 mm, it makes up for this with overpressure, allowing it to punch well above its weight. This allows it to kill any target in one hit, with very few exceptions. The primary armament is also able to fire smoke shells.
On the other hand, the reloading rate is abysmal, clocking in at a little under 20 seconds. This means that if a shot misses or fails to kill the enemy, it will most likely be the death of the G6. At only 5°, the depression angle of the primary armament is sorely lacking, especially if using in a hull-down position. Additionally, the G6 turret can only traverse ±40°, meaning it has a rather narrow cone of fire to the front of the vehicle, giving it a reduced effectiveness when attacked from the side or rear. The high recoil heavy barrel of the cannon relative to the rest of the SPG lends it poor weapon handling characteristics, taking a very long time for the weapon to stabilise.
The G6 also has a large first-stage ammunition stowage at 16 pieces, which is more than enough for this vehicle. It is therefore ill-advised to take more than 16 rounds into battle, since a large quantity of shells poses a risk to ammunition detonation, and 16 is more than enough given the low survivability of the vehicle, and low reload rate & high lethality of the weapon. Horizontal and vertical traverse is adequate, though nothing extraordinary. Commander optics are present, and can be an effective emergency alternative to the primary weapon optics.

Usage in battles
It is ill-advised to use the G6 in Arcade battles. At 136% visibility, it is extremely vulnerable to being spotted, and is an easy target for aircraft. While AB mitigates many of the aforementioned issues with weapon handling and mobility, the playstyle of quick and aggressive combat does not suit the G6.
In Realistic battles, it can perform better. It is best suited to being a long-range support vehicle, using mobility to reach far areas before enemy forces. It is then best to stay in position and hold common flank routes. Playing in a squad is advised as the long reload rate means that players will often rush immediately after you fire, so it's best to have allies to back you up in an emergency. In predominantly rural maps, it is best to stay at long range, and out of sight. In urban environments, staying with the bulk of your team is the best way to maximise survivability.
In Simulator battles, it is much the same as in Realistic. However, this time due to the more tactical and slow-paced nature of SB, you can take your time and plan out strategies to maximise effectiveness. Holding choke points and flank routes should be a priority, and staying at a range of at least 1 kilometre is best for ensuring long-term survival.

History
Background
The G6 Rhino is a Self-Propelled Howitzer, designed and developed by the Lyttelton Engineering Works (now Denel Land Systems, a division of Denel) throughout the late 1970s and 1980s. An indigenous design of South Africa, it was intended to replace the WWII-era Sexton of Canadian origin. The development of an indigenous design as opposed to the purchase of foreign arms is often attributed to the arms embargo (UNSC Resolution 418) on South Africa, passed unanimously by all major world powers - a response to the ongoing apartheid system of racial segregation, as well as escalation of the South African Border War with nearby countries.
Development
Development commenced in the late 1970s, and the first prototype was completed in 1981, with four additional field-test models being used by the mid-1980s. The G5 howitzer was chosen due to its preestablished presence within the South African armed forces. This meant that backwards compatibility allowed for the interchangeable use of spare parts and ammunition, as well as no radical changes to already existing manufacturing plants. The turret, as well as the G5 howitzer were manufactured by Denel Land Systems, and OMC manufactured the chassis. OMC - Olifant Manufacturing Co, was also responsible for the design, development and manufacturing of the Olifant (represented in War Thunder as the Mk.1A & Mk.2) MBT, which was a modified British Centurion tank.
The choice of a wheeled vehicle was intended to increase mine-survivability, reduce fuel consumption, allow for faster deployment times, and reduced wear-and-tear on the roads.
Two countries license-built their own versions of the G6. Chile briefly built it under the designation "CC-SP-45", though the Chilean Army promptly ceased development due to a shift in Augusto Pinochet's foreign policy. Iraq procured the rights to license build the G6 under the name "Al-Manjoon" with the assistance of Canadian artillery engineer Gerald Bull. Bull later went on to design the Al-Fao which is currently regarded as one of the most powerful artillery pieces, and is assumed to be a development of the G6 - be it directly or indirectly.
Combat History
To test its effectiveness in combat, a trial by fire was conducted in 1987, when all four field-test models were deployed in the South African Border War. One vehicle broke down en-route, the other three saw action in Operation Hooper as part of an independent battery. It was critical in the South African success at the Battle of Cuito Cuanvale, where it bombarded an Angolan airfield, and four Angolan MiG-21s were destroyed on take-off. It was clearly demonstrated in this conflict that the G6 was a more than capable medium range SPH system, with future trials showing that it was an extremely accurate piece of artillery.
In 2015, a battery of G6 M1A3s under UAE operation was deployed in the Yemeni Civil War, and were used against militant Houthi positions.

Throughout the 1960s and going into the 1970s, the SADF largely still relied on dated artillery systems from the WWII-era such as the British QF 25-pounder cannon and Sexton SPGs. Recognizing this issue, the military began formulating modernization plans in 1968 which were subsequently formalized in 1973. Shortly afterwards, the SADF procured more modern artillery units such as the American M1 and a version of the Canadian GC-45 155 mm howitzer, designated G5 under SADF service.
However, the SADF also wanted to procure a self-propelled version of the G5 howitzer. To this extent, a project was launched in the late 1970s to fit the G5 cannon into an enclosed turret and mount it onto a highly mobile wheeled chassis. Work on the project commenced in 1979 at the ARMSCOR company, eventually resulting in the G6 Rhino. The first prototype of the vehicle was completed in October 1981 with a total of four being manufactured by 1987.
Immediately after rolling off the factory floor, this initial batch of G6s were pressed into service during the South African Border War. During this period, the G6 underwent its baptism by fire and proved its capabilities during combat operations against Angolan forces, being particularly noted for its excellent mobility and ability to quickly shift positions between fire missions. After the initial deployment, full scale production of the G6 commenced in 1988 and lasted until 1994.
By the end of the production run, a total of 154 G6s were manufactured of which 78 were exported to the UAE and another 24 to Oman. Since the late 1980s, the G6 didn't see any further combat action with South African forces, but it did take part in operations with the UAE armed forces in Yemen since 2015.
