General info

The Iron Duke IV in the garage.

The A34 Comet I "Iron Duke IV" is a gift Rank III British medium tank with a battle rating of 5.0 (AB/RB/SB). The tank was available to be obtained during the 2016 "Chronicles of World War II" after completing 11 "Tank Tasks". Aside from the exterior decoration and premium status, it is identical to the normal Comet in the British tree.

The main purpose, usage and tactics recommendations

General play style

The Comet is an excellent medium tank. It has great mobility and acceleration, able to reach 38 km/h very quickly and stay there in full throttle, but its reverse speed is pitiful like the Cromwell's. Firepower is also a benefit of the vehicle, especially after the unlocking of the APDS shot, giving it the penetration needed to deal with any threat you might encounter. The drawback of the design is the sub-par armour that can be pretty easily penetrated at BR 5.3. One should take advantage of the Comet's low profile and mobility to hide and maneuver from the enemy to catch them at an advantageous angle. The Comet also has a benefit the previous tanks in its branch, the Sherman Firefly, didn't have in the great gun depression. This allows the Comet to more easily fire over hills in an hull-down position to destroy the enemy with the most the best terrain benefit for protection.

Vehicle characteristics

Tactics

Fighting a tank of the same weight classification is relatively easy, but difficult against the more armoured Panther and T-34-85 tanks. Until the APDS shot can be unlocked, more decisive shots will have to be made to take care of these tanks, the Mk.6 and Mk.8 shot are the preferred ammunition to use.. The Panthers should be targeted on the gun mantlet in the front and should be aimed at the gunner to immobilize their firepower and cause crew damage. The T-34-85 is a bit of a hit-or-miss due to the more heavy sloping nature of the armour and the turret. Penetrating through the front hull armour when it is facing directly at you is the best course of action against the T-34-85. Heavy tanks get even more tricky, but easier once the APDS round is unlocked for use. A Tiger I is admittedly an easy tank to deal with due to the vertical slope of the armour. Problems arise with the IS-2 tank that may show up, due to their heavy armour and their tendency to one-shot kill with their 122 mm gun. Distance is not your friend against this tank, the closer the better for your gun to penetrate the weak spots on its frontal armour. A tough situation, but a survivable one.

The best tactic is flanking and "shoot and scoot". Your armour won't stand against T-34's and Tigers you'll meet so don't pick a snipe position and keep firing - sooner or later you will be pinned down. You need to locate a good spot for attack, fire a few shots (comet has a great fire rate: use it) and relocate. Don't mind the damage you made: keep moving! When relocating/hiding behind something keep in mind you have an awful reverse speed of only -1 MPH (-3 KMH).

Pros and cons

Pros:

  • Excellent maneuverability and speed - second only by a little to the T-34-85(D-5T) and Panther D.
  • Good gun, precise and with good penetration values (vertical armour).
  • Access to APDS shot.
  • Great turret armour.
  • Low profile.
  • Great gun depression.
  • 5 crewmen.

Cons:

  • Bad penetration values against sloped armour without APDS.
  • Bad gun damage (without APDS), you'll need to aim at the enemy gunner to have a fighting chance.
  • The 17-pdr does not have as much penetration as other variants.
  • Overall bad armour for its rank,only the turret front has some chance to bounce some hits.
  • Awful reverse speed of only 3 km/h (1.86mph).

History of creation and combat usage

Development

The British experience against the Germans during World War II showed that there were severe deficiencies with their cruiser tanks. The main cruiser tanks in the British inventory was the Crusader tank, but suffered from a gradually inefficient armament and thin armour. A request was submitted in 1941 to the Nuffield Organization and Leyland Motors Ltd for a heavier cruiser tank that could take on the gradually stronger German tanks, the design was also to use components from the Crusader tanks for economic reasons. This became the A24 Cruiser Tank Mk VII Cavalier tank and the A27L Cruiser tank Mk VII Centaur tank, which are both superseded by the A27M Cruiser Tank Mk VII Cromwell tank. The Cromwell ended up as a decent cruiser tank for the British Army, giving great mobility, reliability, and a decent OQF 75 mm gun (or a 6-pounder gun). However, it still had problems, such as being under-gunned against the more armoured German tanks and suspension problems.

It was determined that the British Army needed a tank that mounted the large 17-pounder gun, which would allow the tank to stand its ground against the German panzers. The first attempt was an upgraded Cromwell in the form of the A30 Challenger, but development and production was slow and the first mass-produced tank with the 17-pounder was the modified Sherman Firefly. While the Firefly was adequate, it was a logistical burden when the Firefly is attached with Cromwell troops, which would require the troop to have maintenance requirements for a Cromwell and a Sherman tank. A more standard tank is needed to fix this, and development started on this with the General Staff specification A34.

The developing tank, now called A34 Comet I, was meant to fix the issues from the Cromwell such as the suspension and the track shedding, plus also increase the firepower and speed. The gun mounted on the tank was the "77 mm HV", a specifically built gun for the Comet I which is derived from the 17-pounder. Though using the same projectiles, the 77 mm HV gun uses cartridges with different casings and thus the rounds between the two gun are different and the 77 mm HV produces a lower muzzle velocity for the round, but this allowed easier stowage in the gun due to the more compact size. The Comet I also gave a greater armour protection, a welded armour construction, cast gun mantlet, stronger suspension, a return roller established in the suspension, an electrically traversed turret, and ammo stowage inside armoured bins. The Comet I, though having the power to go faster than the Cromwell, is restricted with an engine governor to preserve the suspension, engine, and tracks. The Comet I entered prototype stage in February 1944, but delays caused production to start at September 1944 and then put into service in Europe at December 1944. By the end of the war, about 1,186 Comet I tanks were made for the British Army.

Combat usage

The first units to receive the Comet I tank was the British 11th Armoured Division, which was delivered in December 1944, and was the only division to be refitted with Comets by the end of the war. The Comet did not perform significantly in the battlefield due to its late arrival, but it was involved in the crossing of the Rhine and the Berlin Victory parade in July 1945. At Europe, the maximum speed of 51 km/h allowed the Comet I to exploit the German highways to travel throughout the entire countryside.

The Comet I saw service after World War II during the Korean War when it started, serving alongside its to-be successor Centurion tank. Though the Centurion was adopted in 1949, the Comet I continued to see service in the British Army until 1958, when it was then decommissioned and sold to foreign countries, which included South Africa, Finland, Ireland, Cuba, and Myanmar. Notable records with the Comet I sales was 41 tanks to Finland, which used them until 1970 and kept them in storage for much longer. In 1959, 4 were sent to Ireland in 1959 and another 4 the following year, the Irish kept them until 1973 before being withdrawn.
