SUB-I-II
Contents
Description
The Mitsubishi SUB-I-II was a prototype for the Type 73 APC meant to replace the smaller Type 60 APC. Going through multiple prototypes, this particular version was tested with a Rh202 (20 mm) as a self-defense and anti-air cannon, though this armament would not see use in the final version.
It was introduced in Update "Apex Predators". The SUB-I-II provides an excellent fire rate with the possibility of an APDS belt in an amphibious yet squishy APC hull only offering up to 20 mm of armour. As such, if positioned correctly against a suitable target, the SUB-I-II can utilize the APDS autocannon to shred their opponent apart.
General info
Survivability and armour
The SUB-I-II has no notable armour. It is dangerous to stand in the open without cover, as the SPAA can be penetrated by any tank or plane. The survivability of this SPAA is very low if any enemy has a direct line of sight on it.
Armour type:
- Aluminium alloy 5083 (hull, gun mount)
- Cast homogeneous armour (cupola)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 20 mm (52°) Upper glacis 20 mm (24-60°) Lower glacis |
12.7+5 mm Top 12.7 mm Bottom |
20 mm (7°) | 10 mm 5 mm Engine vents |
| Turret | 20 mm (conical) | 20 mm (conical) | 20 mm | |
| Cupola | 10 mm (spherical) Base 15 mm (spherical) Dome |
10 mm (spherical) Base 15 mm (spherical) Dome |
10 mm (spherical) Base 15 mm (spherical) Dome |
15 mm |
Notes:
- Suspension wheels and torsion bars are 10 mm thick, while tracks are 15 mm thick.
- Belly armour is 10 mm thick.
Mobility
The SUB-I-II has a modest top reverse speed in RB of -12 km/h so bear that in mind when choosing a good spot to shoot from.

Usage in battles
When hunting for planes, the SUB-I-II should always have some sort of cover to hide behind in case a plane retaliates. When shooting, you should also be mindful of the gun overheating and use all of the rounds in the belt as the SUB-I-II has only 800 rounds at most. If possible, try to remain near a friendly capture point to restock on ammo belts when they run out because the main cannon can shoot at 800 rpm.
Pros and cons
Pros:
- High rate of fire
- Amphibious
- Can penetrate some medium tanks from the side
Cons:
- Low survivability
- Slow speed in water
- Low ammo count
History
Development of the Type 73 APC started in 1967 as a replacement for the Type 60 APC (chassis of the Type 60 ATM). Four prototypes were made during the development, two from Mitsubishi (SUB-I-I and SUB-I-II) and two from Komatsu (SUB-II-I and SUB-II-II). The 20 mm Rh202 version got rejected at last.
