Description

GarageImage CM11.jpg


The CM11 is a rank VI Chinese medium tank with a battle rating of 9.3 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision".

A Taiwanese upgrade to the M60A3, the CM11 "Brave Tiger" is currently the most modern tank in active service with Republic of China Army. It retains the general appearance of the M60 aside from the smaller turret and the unique pagoda-like ERA arrays on the turret sides. Though its mobility and kinetic protection are poor, it has the same 105 mm gun as the M1 Abrams. If used carefully, the CM11 can do some serious damage with its thermal sight and powerful DM63 APFSDS.

General info

Survivability and armour

The CM11 combines the hull of a M60 Patton with the turret of a M48 Patton, and as such the base turret and hull armour is mostly identical to these two tanks, respectively. The M48's bulbous cupola has been replaced with a low-profile version. The armour is quite resistant to APHE rounds, which may be fired by the occasional Object 906, Object 685, and T-55AM-1, but the vast majority of opponents at its rank use HEAT-FS and APFSDS rounds that can cut through steel like butter. To counter the former, the CM11 is slathered with ERA, and can generally survive the first shot from most HEAT-FS rounds. However the ERA offers close to no protection against APFSDS rounds, which are the round of choice in top rank battles.

Post-penetration survivability is also questionable. It lacks blowout racks and ammunition is scattered around the tank, so successful penetrations can reduce the CM11 to a fiery grave.

Armour type:

  • Cast homogeneous armour
  • Rolled homogeneous armour (Rear roof, Engine grille)
Armour Front Sides Rear Roof

Notes:

  • Tracks are 30 mm thick while suspension wheels are 20 mm thick.
  • Belly armour is 19 mm in the front, 13 mm in the rear.
  • 15 mm RHA plate between the engine and crew compartment.


Mobility

Game Mode Max Speed (km/h) Weight (tons) Engine power (horsepower) Power-to-weight ratio (hp/ton)
Forward Reverse Stock Upgraded Stock Upgraded
Arcade 53 13 54 1162 1,431 21.52 26.5
Realistic 48 12 663 750 12.28 13.89

The CM11's mobility is awful compared to its contemporaries. It weighs practically the same as the M1 Abrams while having less than half of the engine power. It is very slightly more mobile than the Chieftain Mk 10, but that is a very low bar, and unlike the Chieftain it does not have strong armour to make up for it. Expect to be among the last to arrive on the battlefield.

Armaments

Main armament

Main article: M68A1 (105 mm)
105 mm M68 Turret rotation speed (°/s) Reloading rate (seconds)
Mode Capacity Vertical Horizontal Stabilizer Stock Upgraded Full Expert Aced Stock Full Expert Aced
Arcade 63 -10°/+20° ±180° Two-plane 21.40 29.65 36.00 39.81 42.35 8.70 7.71 7.11 6.70
Realistic 13.40 15.75 19.13 21.15 22.50

The M68A1 is the same gun used by the M1 Abrams. It enjoys a quicker reload that tops out at 5 seconds. The gun handling is otherwise identical to the M60A3 TTS, which is not great but still better than typical Soviet tanks.

Ammunition

The stock M735 APFSDS round is a fairly good and reliable option. The flat penetration is not exceptional but as a long rod APFSDS, it does well against sloped armor. M735 will easily dispatch any enemy tank that does not have composite armor. MBTs with weaker composite armor like the XM-1 (GM) or M48 Super are still vulnerable.

For tougher targets, the unlockable DM63 APFSDS round will rarely disappoint. It has the highest penetration of any 105 mm APPFSDS round currently in the game, exceeding 430 mm of flat penetration. This is actually enough to penetrate the turret cheek of the M1 Abrams. However, it is overkill against most tanks that the CM11 will encounter. If Silver Lion costs are a concern, do not use DM63 as a primary round unless the CM11 has been uptiered a lot. Tanks to watch out for include the Chieftain Mk 10, Challenger Mk.2, Challenger Mk.3, and Leopard 2A4. These all feature strong composite armor on their turret cheeks that DM63 will not be able to penetrate. Shoot the hull, gun mantlet, or turret ring instead.

The M456 HEAT-FS round is the less effective than the M735 APFSDS when fighting armored targets due to its lower post-penetration damage, lower muzzle velocity, and weakness against composite or reactive armor. It is not a stock round either. Keep a few on hand for hull-breaking light targets.

The M393A2 HESH round is even more effective against light targets but has bad ballistics and low penetration. It can also be neutralized by spaced armor in addition to reactive and composite. The wide cone of damage may be helpful once in a while, so it does not hurt to take a handful, but it will generally not be useful.

Usage in battles

Like most MBTs in the Chinese tech tree, the CM11 should be played in a laid back, cautious manner since its firepower is good but its speed is not nearly sufficient for flanking quickly and catching enemies by surprise. Unfortunately its poor armour and large profile make hull-down sniping difficult, though it does enjoy better gun depression than most PRC/Soviet tanks. It is best to stay close to cover and observe the environment. When the enemies are spotted, pop out, shoot first, and try to at least cripple them. The DM63 APFSDS has very good penetration for a 105 mm round, easily penetrating almost all targets that the CM11 is likely to encounter. The fast reload time ensures rapid follow-up shots. If the teammates do a good job distracting the enemy team or the CM11 somehow manages to flank successfully, several targets can be knocked out in rapid succession. Make good use of the thermal optics, as not all tanks at its battle rating feature them and they are very advantageous for spotting enemies early.

As a whole, the CM11 is somewhat like a tank destroyer, having a powerful gun but not much else. In a meta favoring high speed and high protection, it is rather out of place, but it can still work in the hands of a skilled player with good aim and reflexes. Trust the DM63 APFSDS, stay alert, shoot first, and avoid getting shot in return.

Pros and cons

Pros:

  • Access to powerful DM63 APFSDS
  • Fast reload, topping out at 5 seconds like the M1 Abrams
  • Heavy ERA coverage, decent resistance to chemical rounds
  • Has a thermal sight for the gunner
  • Low-profile cupola
  • Stock M735 APFSDS is economical

Cons:

  • Large target
  • Poor mobility
  • ERA has negligible kinetic protection
  • Vulnerable to APFSDS rounds

History

Development

In 1980, the Republic of China (ROC), also known as Taiwan, created the Armored Vehicle Development Center. It was created partially to develop the CM-11 tank. The Republic of China Army (ROCA) needed a 2nd generation main battle tank (MBT), and they wanted to acquire one without breaking any limitations placed on the ROC by the US-PRC Joint Communique. As such, they decided to create a hybrid design using the M48A3 turret and the M60A3 hull. In the ROC, it is known as the CM-11 Brave Tiger, whereas the United States designated it as the M48H for M48 hybrid. To create the tank, the ROC imported M60A3 hulls from the United States along with M68 105 mm cannons and M48A3 turrets. They imported the commanders cupola from Israel. Two prototypes were finished in 1988 and the ROCA ordered 450 CM-11 tanks.

Design

The hull of the CM-11 is from the M60A3 tank built in the US. As such, the CM-11 uses a torsion bar suspension system, and is powered by a Continental AVDS-1790-2C diesel engine producing 750 hp. The turret is from the M48A3 tank, but with the Israeli Urdan style commander's cupola with a low profile. Armament consists of an M68 105 mm cannon, the commander's 12.7 mm (.50 in) M2 Browning machine gun, a co-axial 7.62 mm M240 machine gun, and the loader's 7.62 mm M240 machine gun. The fire control system is the same system as used by the M1 Abrams, and the M68 105 mm gun has a two-plane stabilizer. The optics and thermal imaging are also as modern as those on the M1 Abrams, giving the CM-11 night fighting and fire-on-the-move ability. The design has a number of drawbacks though. The main battle tanks of the People's Liberation Army (PLO) are the 2nd generation ZTZ/Type 96 and 3rd generation ZTZ/Type 99, which mount a 125 mm gun which can reliably penetrate the armor of the CM-11. This is because the CM-11 is a design that has become outdated in terms of combat capability, as its parts were designed in the 1960's. To counter this, it was attempted to put explosive reactive armor (ERA) from the French company GIAT on the CM-11, but that would tax the suspension too much, so the idea was dropped. In 2012, a CM-11 was seen at an exercise mounting ERA designed by CSIST, which featured extreme angles to increase the chance of enemy shells deflecting off of the armor.

Production and Service

450 CM-11 Brave Tigers were ordered and delivered. They are still in service with the ROCA, and are likely to be upgraded in the 2020's after the upgrade program for the M60A3 TTS in ROCA service is completed.

During the 1980s, armed forces in Taiwan were looking for more capable AFVs. However, as some existing agreements with the USA prevented the supply with more advanced US equipment, such as later versions of the M60 and the newer M1 Abrams tanks, military production was forced to develop an indigenous design.

While still retaining access to supplies of older US equipment and components, the decision was made to create a hybrid tank from the available components and outfit it with the latest electronics. As such, Taiwanese engineers took the hull and chassis of the M60A3 and combined it with the turret of the M48, while installing the M68A1 105mm cannon and the latest US fire control systems available.

The result of this undertaking was the CM11. In the late 1980s, two prototypes were sent to the US for comparative tests against the M60A3, where the CM11 outperformed its counterpart in gunnery trials. Shortly after these successful tests, the CM11 officially entered service in 1990.

However, as the protection was seen to be somewhat lacking, the decision was made to upgrade the CM11 with ERA packages obtained from GIAT in the early ‘90s. Due to substantial weight increases and associated upgrade costs however, this modernization effort was only applied to about a dozen vehicles. In total, 450 CM11s were built for the armed forces, still representing the spearhead of the country’s armored units today.
