General info

Survivability and armour

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.

Ammo racks of the M19A1 (Japan)

Notes:

• The visual discrepancy concerns racks and clips: racks are modelled to contain 5 clips while clips are modelled to contain 5 rounds.
• The game however shoots 8 rounds per clip and racks disappear after varying amounts of rounds have been shot. Example: Racks 2 to 13 are the same size (25 rounds) but some disappear after 2 clips were fired (16 rounds), some others disappear only after 1 clip (8 rounds) has been fired.
• No rack is emptied before you have fired 21 clips out of 44.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: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).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
