Description

The Light Tank M24 SDF is a Rank III Japanese light tank with a battle rating of 3.3 (AB) and 3.7 (RB/SB). It was introduced along with the initial Japanese Ground Forces tree in Update 1.65 "Way of the Samurai". This Japanese vehicle is identical to the American M24 Chaffee.

General info

Survivability and armour

The M24 Chaffee has thin armour on all sides, and can only effectively resist machine gun fire or very low-penetrating guns like 20mm autocannon. Its crews are also very close to each other, increasing the chance of it getting one-shotted. The V-shaped gun mantlet might bounce some small caliber shells if you are lucky enough. However, don't rely on it as the rest of the tank is still poorly protected. Common guns like the 75mm M1 or 76mm F-34 / ZiS-5 can easily destroy the M24 with one shot

Armour type:

• Rolled homogeneous armour
• Cast homogeneous armour (Gun mantlet)

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	25.4 mm (60°) Front glacis 25.4 mm (44°) Lower glacis	25.4 mm (13°) Front 12.7 mm (13°) Rear	12.7 mm (71-74°) Top 19 mm (1-43°) Bottom	12.7 mm

Armour	Sides	Roof
Cupola	38.1 mm	38.1 mm

Notes:

• Suspension wheels and tracks are 15 mm thick.
• Belly armour is 12.7 mm thick.
• Gun barrel is 20 mm thick.
• Gun breech is 300 mm thick in structural steel

Mobility

The M24 (Japan) travels at an average of 40 km/h on/off-road which is the average light tank speed. It also responds fast when reversing. Thanks to its short and wide tracks it is able to turn quickly. However the acceleration is poor, making it to feel sluggish when performing short manoeuvres.

Armaments

Main armament

The 75 mm M6 gun has two types of AP, one HE and one smoke shell to choose from. The M61 shot, which is an APCBC, is generally better than the M72 AP. It has 63.7g explosives which brings a deadly blast once penetrated, has better penetration (104mm max) and it has a slightly lower chance of ricocheting. With the M61 shot, the Chaffee is able to one-shot plenty of tanks at its BR like the M4, T-34, Crusader or even the KV-1

• M61 shells are for:
  

Heavy tanks like KV-1 (L-11)s and KV-2s or possibly Shermans if in a mixed game. Medium tanks with applique armour such as the Panzer III Ausf. M and etc.

• M72 shells are for:
  

Medium tanks and Light tanks like Panzer III Ausf. J1 or the T-50.

Machine guns

The two machine guns on the M24 Chaffee are the good old .50 cal M2HB and the 7.62 mm M1919A4. The roof-mounted .50 cal can traverse 360 degrees and has great depression & elevation, posting a big threat to any plane that is flying too close to the M24. It has an unbelievable penetration of 31mm at 10m, meaning it can easily penetrate plenty of lightly armoured vehicles and even the side of some low rank medium tanks. (eg. Sd.kfz.234 series, side of Pz.III / IV) The 7.62mm, on the other hand, can only efficiently damage exposed crews due to its low penetration.

Usage in battles

The M24 (Japan) is a very good tank with a fairly interesting play style. Instead of being permanently stationed at a single point and continuously firing at an enemy, this tank offers impressive maneuverability and speed which allows it to perform impressive flanking maneuvers. The M24 can travel at around 38 km/h forward and -25 km/h backwards. Its reverse speed is very good if a quick getaway by going backwards is needed. Thus, this tank excels at "peek-a-boo" tactics in which one hides behind a rock or other large piece of cover and repeatedly inches out to fire at an enemy.

The tank offers a 75 mm M6 gun, which has a slower reload than the Sherman's 75mm M3 gun but is otherwise the same. Its shells come in handy for certain tanks; they generally penetrate armour very well. It is rare to experience a ricochet or be to unable to penetrate any armour.

Do not: Continuously shoot at a tank without backing up/moving. The vehicle's armour is very thin and will most likely be destroyed if it stays in one position and does not stop changing positions. Always try to get the first shot off in a head-on attack. Typically, the best shell to use is the M61 shell but it can also be beneficial to have M72 shells as well.

Another way to go around is to flank the enemy. If attacking with a more direct approach, keep hidden behind a building or boulder and pop out every now and then to take a shot at the enemy. Also, prioritize targets who are busy fighting others and cannot retaliate. Usually, after the first shot, it may disable their tank depending on what it is. Disabling the enemy tank's crew, tracks, engine, etc. allows for retaliation without the risk of any incoming enemy shells.

Pros and cons

Pros:

• Low profile
• The best cannon for light tanks in its rank
• Fast turret traverse
• Equipped with a vertical plane stabilizer, allowing for more accurate shots on the move or shoot-n-scoot tactics
• Pintle mounted HMG allows for air defense
• Very agile
• Very fast reverse, thanks to the 4-speed reverse gear

Cons:

• Thin armour on all sides
• Low ammo count can be a problem in long games or RB/SB matches
• Vulnerable to nearby explosions
• Reload is quite slow for its caliber

History

Development

As early as 1942, the light tanks M3 and M5 Stuart have been seen as severely lacking in the modernizing design of tanks and how they fight. The armour was seen as insufficient and the 37 mm gun was also deemed useless against newer German tanks like the Panzer III and Panzer IV. The system needed an upgrade, specifically a light tank that mounts the 75 mm gun seen on the Shermans. An attempt to mount a 75 mm gun on a Stuart was deemed inefficient as it reduced ammo stowage and left the armour too thin on the design.

In April 1943, Ordnance with Cadillac started on a project for the new light tank, designation Light Tank T24. The powertrain and transmission of the M5 Stuart was used with the ultimate goal of producing a vehicle weighing less than 20 tons. This left the vehicle with relatively thin armour to keep light. At the time, a lighter 75 mm gun was developed for mounting on the B-25 Mitchell bomber without sacrificing performance, and this was mounted onto the light tank in development. The tank used 410 mm wide tracks with a torsion bar suspension that greatly improves cross-country travel. The engine was a Cadillac 44T24 V-8 petrol engine. The chassis was designed with the expectation that it would be used as a basis of many different vehicle roles so it was called the "Light Combat Team". The light tank end design had a low profile at 9 ft. 1 in. height and featuring a crew of five with a three-man turret, an improvement over the two-man turrets of the Stuarts. The first finished vehicle arrived on October 15, 1943 and was deemed a success, starting a contract for 1,000 units that was later raised to 5,000 units. The vehicle was classified as the Light Tank M24 and as the Chaffee by the British after US General Adna R. Chaffee, Jr., who helped develop some of America's earliest tank designs. The vehicle was produced by Cadillac and Massey-Harris from April 1944 to August 1945 with a total of 4,731 units produced.

Japanese Service

In July 1st, 1954, Japan set up its post-war military force, the Japan Self-Defense Forces with the purpose of defending Japan should it come under conflict in the ongoing Cold War between America and the Soviet Union. To jump start the remilitarization, America gave the newly formed JSDF several M24 Chaffees along with some M4A3E8 Shermans. The M24 would soon be retired once it was found that they were unable to contend against the Soviet's T-34-85, leading to a limited use until replaced by more capable tanks.
