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 turret is open topped which can allow for weapons of any type to damage the gunner. 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
- Can destroy most light vehicles and some medium vehicles through weak spots
- Excellent main weapon traverse angles for an APC
- Dual feed system can allow for quick switching of belts if ammunition is not fully expended
- Hull machine gun can be used to destroy unarmored targets, spot enemy vehicles, or knock down foliage
- Low profile hull
- Amphibious
Cons:
- Low survivability
- Open turret with exposed gunner
- Low ammo count
- Difficulty in damaging heavily armored targets
- Slow speed in water
- Engine turbine is loud and can give away the vehicle's position
