|This page is about the medium tank Chi-To Late. For the early version, see Chi-To|
The Type 4 Chi-To Late is a Rank III Japanese medium tank with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update 1.69 "Regia Aeronautica". An improvement over the original Chi-To with a more sloped hull for better protection.
Similar to the Chi-To, the tank's mobility is only average with average armour and a decent gun. Like most Japanese tanks in Rank III, it is most effective as a sniper due to its thin armour, low turret traverse, and good gun depression. Sticking to the rear and letting heavier units advance is most ideal, however this is not always possible and you will need to push with your team on the front at times. At times like this, play cautiously and stick to cover, as your thin side armour, poor hull traverse, and poor turret traverse can result in you easily being flanked. The lack of APC rounds like all Japanese guns gives the tank poor performance when fighting heavily sloped armour like the T-34's or IS's, and ricochets will be a common occurrence. It is best to aim for flat spots of armour where you will easily penetrate and let the HE filler do the rest.
A more armoured tank than the Chi-To before it, the Chi-To Late is a bit more forgiving. Like many Japanese tanks of Rank III, the Chi-To Late posses the Type 5 75 mm gun that allows it to penetrate nearly everything it fights with decent consistency. The high muzzle velocity, above average pen against flat and gently sloped armour, good gun depression, and good explosive filler make the tank a good sniper in most cases. However, unlike the Chi-To, the sloped armour and smaller, symmetrical turret design make the tank more capable in a brawling situation where you are more likely to get hit.
In terms of raw thickness, the armour is the same. However the Chi-To Late's hull armour is roughly equivalent to that of the KV-1 (L-11) frontally and therefore is fairly safe from many guns beneath its battle rating such as the M3 75 mm, QF 57mm 6pdr, and F-34 76 mm. Guns of its rank such as the M1 76 mm, KwK 40, 85 mm D-5T, or the QF 17pdr will not struggle with its armour however, so you should not push as if your armour is effective as such.

Usage in battles
As previously stated, the Chi-To Late best performs in the role of sniper, engaging hulldown at medium to long range against opposing medium tanks. The good gun depression, average mobility, and good reverse speed allow you to make it to good positions at an average pace and allow you to reverse back into cover when reloading.
Against most heavies such as the IS-1/2, Tiger, or Panther, it is only worthwhile to engage if you are already entrenched in a solid defensive position. Your gun's lack of APCBC gives you poor performance against slopes and rounded armour on the IS, Panther, and angled Tigers, making any ranged engagement near useless. Against tanks such as the Jumbo 75 or 76, it is best to disengage and flank them or have teammates flank them. Against all other medium tanks, shots to the hull will suffice at most range.
The M4A3E2 Jumbo could be a menace if not handled properly as they are nigh impenetrable from the front due to its thick armour. Either try for a very precise shot through the MG port in the front or shoot the armour behind the tracks if they are angled. The best way to deal with a Sherman Jumbo is to shoot it through the side or between the side plate and the tracks. There is a small gap between the top of the tracks and the bottom of the side plate that can be easily penetrated by the Chi-To Late, and a successful penetration here usually results in a one-shot, or a destroyed/alight engine. This weak spot is relatively easy to exploit as most Jumbo drivers make the mistake of angling their armour, which gives you full view of this weak spot. If you are struggling to hit it, then a shot through the drive wheel at an angle of 45º or more usually works quite well also. You should feel no pressure to get this right the first time, as a well-angled Chi-To Late can reliably bounce the Jumbo's shells, unless the Jumbo in question happens to be sporting the 76mm M1A1 cannon.
The IS series of tanks can also be a bit of a bother to deal with. At this battle rating, you may find the IS-1, IS-2 or IS-2 mod. 1944 (rare). However, they can be defeated by exploiting the shot trap on the turret front (requires some luck), shooting the driver's hatch on the front or the gun mantlet (requires extreme precision and luck), shooting the lower frontal plate (the most reliable way to kill an IS) or shooting the frontal armour plate from a 90º angle. That being said, your tank can still one-shot the IS series you'll face by shooting directly beneath the turret ring.
You may encounter the German "Big Cat" tanks (Tiger H1, Tiger E, Panther D, Panther A) if you get seriously up tiered. In this case the best thing you can do is hit them from the side, which usually results in a one-shot. If facing a Tiger (or any German Big Cat for that matter) from the front, you should retreat. However, if his frontal plate is not angled, then it might be worth a shot to shoot between the machine gun port and driver's hatch, which will result in a one-shot. As for the panther, try to exploit the shot trap on the turret, but only as a last resort. Your first port of call should be to shoot the drive wheel, basically following the same tactics you'd use for dealing with a Sherman Jumbo.
As for some other enemies:
A42 Churchill VII: do not engage from the front at all. Sneak around to the side and shoot there. ARL 44: shoot the sides. It's not worth facing this tank head on, it's too much of a risk. ARL 44 ACL-1: aim for the turret if you face this tank from the front, then finish it from the sides. Be careful not to get shot. M6 Heavy: the frontal armour on this thing can be a bit fiddly. Aim for a spot that doesn't seem to have more than one armour plate layered on it.
Most tanks you face can penetrate you frontally if they shoot your frontal plate when it is not angled. It is recommended to get the first shot off and then retreat, and make a second surprise attack. Most of the time, a penetration results in a one-shot with this tank. You can penetrate pretty much any medium or light tank frontally by shooting the upper front plate, so use that to your advantage.
Pros and cons
- Sloped hull armour, a first in Japan tank designs, roughly equivalent to the hull of a KV-1 frontally and can withstand several lower-rank guns.
- 75 mm Tank Gun Type 5 has good muzzle velocity, penetration, and filler.
- Good gun depression.
- Smaller turret than the Chi-To.
- Good reverse speed.
- Thickest side armour of all Japanese tanks tied with the Chi-Ri II at 35mm. Resistant to .50 cals.
- Symmetrical turret placement and gun placement in the turret, no odd angles of fire like the Chi-To.
- Great penetration and explosive filler, a successful penetration usually results in a one-shot.
- 42 km/h top speed is quite respectable.
- Poor turret traverse.
- Average acceleration and mobility, easily beat by Pz.IVs, Shermans, and T-34s.
- Hull cheeks make angling difficult.
- Turret armour is no different from Chi-To, still easily penetrated by any gun it can see.
- Lack of APCBC round gives poor performance versus sloped armour. Expect ricochets against Russians and Americans.
The lackluster performance of Japanese tanks in World War II called for the development of newer medium tanks in the Imperial Japanese Army. The standard tank of the time was the Type 97 Chi-Ha, which has its chassis used in many expedient models to provide a bigger gun for the Japanese inventory such as the Chi-Ha Kai, Type 1 Chi-He, Type 2 Ho-I, and Type 3 Chi-Nu. By the time of Chi-Nu, however, the Chi-Ha chassis was becoming outdated and so a new tank design using an improved chassis was needed for future development.
In 1943, development started of the Chi-To tank, which features a new chassis and more powerful engine. Its armament is a 75 mm gun based off the Type 88 anti-aircraft gun, giving it a high-velocity weapon. Armour on the tank was welded and was quite thick in comparison to its predecessor at 75 mm thick. The tank was accepted for service in 1944 and was expected to enter mass production with 20 per month at Mitsubishi and 5 per month at Kobe-Seiko. In terms of Japanese armour development, the Chi-To was the most sophisticated tank to enter production levels.
Despite its potential, the Type 4 Chi-To was never made in large numbers. At the war's end, only six chassis were made, with only two of those made into tanks. The tanks would be found by the U.S. occupation forces following Japan's surrender in World War II. The tanks were then transported to Aberdeen Proving Grounds for tests and would eventually scrap them in October 1952.
