General info

The XM-803 in the garage.

The Tank, Combat, Full-Tracked, 152-mm Gun/Launcher XM-803 is a Rank VI American medium tank with a battle rating of 9.0 (AB/RB/SB). It was introduced in Update 1.79 "Project X".

The main purpose, usage and tactics recommendations

General play style

The tank plays very much like the M41A1 Walker Bulldog. Players familiar with the hit and run play style will easily adapt to the XM-803. Its fast speed, especially with full upgrades and aced crew, allows it to maneuver into spots not typically accessible by less mobile tanks. Utilise this to an advantage to set up ambushes as this is how you will get most of your kills. It's important to recognise when an engagement is not beneficial to you so that you may get a better position or escape from the threat.

Despite the initial appearance of strong frontal armour, it's important to remember when compared to its counterparts at its rank, it is not nearly enough to defeat threats head on such as the T-64A. Even ATGM from missile vehicles such as the Raketenjagdpanzer 2 HOT will penetrate the turret and upper glacis plate. Even other Rank V tanks can and will penetrate from the front. Because of the rather condensed placement of crew and ammunition you will most likely die. Because of this it is critical you get the first shot off in an engagement and ensure it is either a kill shot or one that cripples the threat to such a capacity they either cannot engage or will instinctively panic and try to run to repair or determine your engagement location.

The gun is especially versatile and powerful with a wide range of ammunition selection but you will generally find your cannon-launched ATGM's and sabot rounds able to get the job done in most situations.

Essentially if you treat this tank like a light tank or fast medium, your survivability will increase dramatically. The low silhouette makes the tank especially difficult to hit at longer ranges. Because of the accurate cannon, you will also find it to be easy to engage at longer ranges, which will maximise your strengths while reducing your targets.

In summary, the XM-803 is a great addition to any end game lineup as it provides great flexibility in almost all engagements and is well worth the time and investment to acquire.

Vehicle characteristics

The XM-803 handles like virtually no other vehicle in the game in terms of its ability to pickup and maintain speed over various terrains. Cross country mobility is arguably the best currently available in the game and is one of the signature traits that stands out about it.

Unlike the Soviet T-64A (its main rival), the XM-803 does not utilise composite armour, but an air gap that forces munitions penetrating the initial layers to lose their mass by fragmenting apart before moving to the next layer of armour. This general design concept has been in use as far back as WW2 and is even used to this day on modern fighting vehicles.

Spaced armour works wonderfully well against shaped charge munitions or any other munition with explosive filler provided it is of a stronger protection rating. Proceeding weapons and munitions development has seen this benefit decreased with either more powerful or tandem charge warheads and can be seen in-game against weapons that proceeded different designs of spaced armour. As such you will find weapons that were designed to defeat spaced armour such as the HOT-K3S ATGM and BAE Swingfire system that will penetrate it. However the spaced armour in the XM-803 works exactly as it was designed to do against older anti-tank missiles, HEAT, HE, and HESH munitions.

The most important feature that makes a tank is the cannon. In this department, the XM-803 is no slouch. The 152 mm gun launcher system (similar to the one used on the M551 Sheridan), but with a longer barrel and is capable of firing a variety of munition types including an experimental APFSDS round, a traditional HEAT round (with high penetration), an experimental smoke round, and lastly the very capable and proven MGM-61C Shillelagh. This wide range of munition choices gives the operator a variety of options in pre-combat configuration which can greatly either hinder or enhance the tankers capability on the battlefield. The benefit of a longer barrel compared to its Sheridan counterpart ensures the XM-803 is much more accurate at range and that the rounds leave the barrel at higher velocities thus increasing their overall damage dealing capabilities.

Additionally the 152 mm gun launcher gets equipped with an auto loader, greatly reducing its time between followup shots on a target. For targeting, the option to equip an incredibly accurate laser range finder is available. Additionally the 7.62 mm machine gun mounted in the turret can be used for range finding as well.

The XM-803 features the standard NATO track and rubber block design. The rubber track blocks provide great traction off road and on road compared to all metal tracks found on other fighting vehicles as sliding on a short halt or drifting is minimised.

Because of the elevated engine deck, gun depression is decreased significantly when firing or aiming the gun over the rear of the tank.

An unconventional feature at the time was that the XM-803 was designed to house all the crew members in the turret. Because of the autoloading system, the need for a loader was eliminated and due to an attempt to further lower the tanks silhouette, the driver was located to the turret with the gunner and commander. This can have potentially devastating consequences on the battlefield as the crew can easily be injured or killed by penetrating munitions entering the crew compartment.

For defensive countermeasures, the tank is equipped with two quad barrel externally mounted smoke canister launchers on both sides of the turret, which can provide either a defensive screen for yourself or friendly forces. These launchers can be fired in pairs of two. Keep in mind the smoke grenade launchers are operated by the gunner so should he become incapacitated in a fight, you will not be able to launch them until he is either replaced by another crew member or you have the crew replenishment consumable unlocked.

Due to its low profile and effective array of camouflage options, the XM-803 scores high marks in the concealability category. The addition of various foliage can further increase the ability to conceal the tank.

Tactics

Ambushing is your strength. As covered previously utilise your speed to get into firing positions quickly and cause chaos and confusion among the enemy.

The XM-803 can also quickly capture objective points and when used properly hold positions so long as it does not stay in any one place to long.

Scoot and shoot tactics will benefit you as well as terrain masking techniques.

Should you have to fight in closer engagement ranges or in close quarters, it is critical to always remember that your armour will not protect you; however, your speed, fast rotating turret, and maneuverability will. Provided you utilise these to your advantage, you will be able to control the fight. Recognise when you are being baited into an ambush and avoid them as you don't stand a great chance of conducting a counter ambush due to your weak armour, which will allow you to be killed easily at close range.

If you have found yourself to be the victim of an ambush from an opponent, launch a smokescreen, escape, and reassess for a counter ambush.

The XM-803 benefits greatly from squad play. A skilled lone XM-803 is most certainly a threat on the battlefield, but two or even three XM-803's working in conjunction with each other in a squad is an extreme danger to the opposing team as the use of squad tactics in combination with the great strengths of the tank can almost completely control the momentum of the conflict.

Specific enemies worth noting

Counter-tactics

The XM-803 is still your average medium tank with weak side armour. Thus, flanking is a good strategy to take for a shot at the weak spots. Go for the ammo, which is located in front of the engine, or in the protruding end of the turret. If in a head on engagement, shoot it directly below the gun, but above the upper glacis. This spot has 250 mm of armour with no composite armour. This shot, if successful, should knock out most of the crew, and maybe even the horizontal drive, allowing for a flank in a fast vehicle.

Pros and cons

Pros:

  • Has spaced armor
  • Stock ammunition consists of the good MGM 51C "Shillelagh" Guided Missile, means no ammo costs for using it, plus a decent but inferior HEAT Shell.
  • Has access to APFSDS Shells with 380 mm of penetrating Power on a 90° angled armour plate @ 10m.
  • Extremely fast in both forwards and reverse.
  • Fast acceleration.
  • Top mounted 50 cal can allow you to damage low-flying aircraft
  • Lower battle rating than MBT-70 despite only minor changes

Cons:

  • Long reload on the gun (10 seconds) which cannot be improved since it is an autoloader
  • The spaced armor is not composite armor and cannot provide adequate protection against most guns of it's tier
  • Weak sides and LFP
  • Ammo racks are large and can be easily hit, and does not have blowout panels
  • Vulnerable to the rear due to raised engine deck
  • Cramped interior, loss of more than one crew member more likely when penetrated
  • Does not have access to the roof-mounted 20mm on the MBT-70 which could be very useful in certain situations

History of creation and combat usage

By 1969, the MBT-70 project was over five times more expensive than planned. West Germany backed out of the join project in 1970 to focus on developing what eventually became the Leopard 2; meanwhile the United States attempted modifying existing MBT-70 designs and prototypes to reduce production costs. The result was the XM803, although it was ultimately just as complex and expensive as the MBT-70. The project was cancelled in 1971, with funds being re-allocated to the XM-1 program.
