Description

The Twin Gun Motor Carriage M19A1, like the M16 MGMC (Japan), was American surplus equipment at the end of WWII, and was gifted to the start-up of the JSDF. Serving in the JASDF and JGSDF, they were in service until 1979 when they were deemed obsolete.

It was introduced in Update "Direct Hit". Being a simple hand-me-down from the US, it plays and is exactly the same as the M19A1, offering 2 x 40 mm in a large open-top turret. Having relatively high armour penetration and the benefit of being built on the chassis of the M24 Chaffee, it can be used to flank and demolish ground targets. Fighting air targets with the M19 may prove more difficult than previous Japanese anti-aircraft vehicles: offering 40 mm auto cannons, the fire rate is diminished but is exchanged for increased shell velocity and single shell damage potential that can shred planes with a single hit.

Armour type:

• Rolled homogeneous armour (hull, turret)

Armour	Front (Slope angle)	Sides	Rear	Roof
Hull	12.7 mm (59°) Upper glacis 12.7 mm (45°) Lower glacis	12.7 mm (11°)	12.7 mm	12.7 mm
Turret	12.7 mm (cylindrical) Gun shield - lower part 12.7 mm (spherical) Gun shield - upper part	8 mm (cylindrical) 8 + 12.7 mm (cylindrical) Turret base	8 mm (cylindrical) 8 + 12.7 mm (cylindrical) Turret base

Notes:

• Suspension wheels are 10 mm thick while tracks are 15 mm thick.

The M19A1 (Japan) is so lightly armoured that it is very vulnerable to nearby ammorack detonations, bomb blasts and even heavy MG fire can reliably penetrate the vehicle from beyond 1,000 m. As the M19A1 (Japan) has an open-topped turret, gun servants are also very exposed to MG fire, artillery strikes and plane strafings.

Notes:

• Ammunition is modelled as 44 clips of 8 rounds
• The visual discrepancy concerns the total number of rounds: 312 rounds are modeled but you can pack 352 rounds.

Usage in battles

Due to the lack of armour, this vehicle should never be used to engage ground vehicles. Keep it for engaging air targets, but always be aware of the limited ammo that's available.

Pros and cons

Pros:

• High-penetrating 40 mm rounds
• Capable of penetrating medium and light tanks and ground vehicles side-on, allowing for flanking tactics

Cons:

• Low rate of fire cannons
• Little armour and open roof leads to high vulnerability against any damage one may take

History

Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
