General info

The M36 in the Garage.

The 90-mm Gun Motor Carriage M36 (or the M36, unofficially the Jackson) is a Rank IV American tank destroyer with a battle rating of 5.7. It was introduced in Update 1.49 "Weapons of Victory". The M36 is an upgrade of the M10 GMC, owning a more powerful gun in the form of the 90 mm. This vehicle can be a great threat for enemy and very fun to play if used correctly.

The main purpose, usage and tactics recommendations

General play style

Play style with the M36 should be about the same as the M10. The speed is about the same and armour is still just as thin, but it has an improved turret traverse rate and a 90 mm gun, making it able to engage targets much easier.

Vehicle characteristics

Tactics

The situations where this TD shines are in flanking maneuvers and sniping engagements.

Specific enemies worth noting

At the BR the M36 is introduced, pretty much every other tank out there can easily take out the M36. Extreme use of angling and "Shoot and scoot" tactics need to be played to avoid being killed very quickly.

Don't try to face enemy up front and personal if you can help it, their armour is probably good enough to shrug off the 90 mm, especially if its a heavy tanks, while the M36 armour would be cut through very easily. The best tactic is to try and get to the sides of these tanks and hit their more vulnerable areas.

Counter-tactics

Pros and cons

Pros:

  • Access to 90mm gun and all its ammo types.
  • Good handling off road.
  • Good gun depression.
  • Powered turret traverse give better turn rate than the M10
  • .50 cal machine gun for AA defense.

Cons:

  • Armour is very thin, M10 thin.
  • Open top vehicle, vulnerable to strafing and artillery.
  • Slow acceleration.
  • Reverse speed is bad.
  • Unable to perform as efficiently as most other vehicles in it's BR bracket due to armour and speed deficiency - requires careful usage to get the most from it.
  • Outmatched by most contemporary enemy tanks.

Modules and improvements

  1. M82 shot (APCBC). This will greatly improve your killing power.
  2. Parts. So you can repair.
  3. Adjustment of fire, to improve gun accuracy.
  4. FPE, to put out fires in the event you aren't one shot.
  5. Elevation Mechanism, to improve gun accuracy.
  6. Your discretion from here. M304 shot (APCR), Engine, Horizontal Drive are all good next choices. Engine is probably the best bet if taking into RB, but less important in AB.

History of creation and combat usage

Development

United State's anti-tank doctrine called for the formation of a tank destroyer force filled with vehicles that are fast and have powerful guns. One of the vehicle designed for this job was the M10 GMC carrying the 3-inch M7 gun. While adequate at the time of its introduction, later in the war it was encountering more heavily armoured German vehicles that could withstand its caliber. Some M10 were upgunned to the 76mm gun, but even that was determined to not be enough. The army needed a tank-killing cannon to be placed on its most numerous tank destroyer vehicle to deal with any armoured threat that could possibly come.

The 90mm gun started as the anti-aircraft M1 and M1A1 gun. It wasn't until the M2 model that it earned a dual-purpose role of anti-aircraft and anti-tank in May 1943. Finally, it was decided to mount the mighty gun onto a vehicle, starting with the M10 GMC. The tank mountable variant was called the 90 mm M3 and was tested on the M10 tank destroyer in early 1943. After installing a modified turret onto the M10 body, the vehicle was designated the T71 GMC , it was approved for service and renamed as the M36 GMC. The nickname Jackson for the M36 was given in September 1944 by Ordnance Department, however this nickname never saw use during war documents. The nickname only became well-known to the public in the 1970s, and soon became synonymous to the vehicle. Like its predecessor, it features an open-top turret and exposes the crew to the elements and enemy fire. However, a postwar modification allows a folding armoured roof to protect the crew from rain and shrapnel.

Combat usage

The M36 GMC arrived at Europe in September 1944. Though 1,400 were produced during the course of the war, the demand for self-propelled 90mm guns were so high that 187 Medium Tank M4 Sherman were converted with the 90mm and sent as the M36B1. The 90mm was met with much approval by not only the crew, but other units around the area as the 90mm could deal with the thick German armour on the Panthers and Tigers. The M36 GMCs were deployed in the Battle of the Bulge along with its other tank destroyer types, where it took out many German tanks with ease due to its high-power cannon and ability to ambush the tanks by the flanks. Humorously, there was an account sometime in March 1945 where a unit of the 635th Tank Destroyer Battalion radioed in to their logistic support asking why their newly supplied 90 mm shells were more than a foot too long for their gun chambers. A few forwarding later got the message to a Captain Elmer Gray, who happened to be looking for the misplaced rounds for the new "Super Pershing" doing combat tests.[1]

At the end of World War II, The M36 GMC's role in the tank destroyer doctrine became obsolete. Mainly due to increasing prevalence of well-armoured tanks that could do its job more efficiently such as the M26 Pershings (which also had the 90mm gun), but also the lack of German AFVs at the time of the war and a study on ammo usage indicates that the tank destroyers spent more time supporting infantry with high-explosive shells than killing tanks with armour-piercing, rendering the anti-tank section an unnecessary component in the modernizing armoured forces.

The M36 then served in the Korean War, able to destroy all the Soviet tank designs used by the North Koreans and the Chinese. An addition of a ball-mounted machine gun on the assistant driver's side was done as well. The M36 served well with the South Koreans until American M26 Pershings and M46 Pattons could be built up as reinforcements. Aside from that, the M36 was exported to many countries and are still in use by some today. Some of the notable post-World War II conflicts the M36 GMCs served in was the First Indochina War, Indo-Pakistani War of 1965, and the Croatian War of Independence of 1991, which proved that the M36 GMCs were still useful to countries half a century after they were introduced.
