| − | {{tankMobility|abMinHp= 420|rbMinHp= 262}} | + | {{tankMobility|abMinHp= 420|rbMinHp= 262}}As a light vehicle, the M19A1 is agile. While it has a high top speed, the acceleration is quite slow: expect a cruise speed around 40 km/h instead. The reverse speed is very high, allowing you to pull out of dangerous situations quickly. The lack of neutral steering makes turning on the spot slow (3 km/h): make sure to build a little speed before turning and you'll turn faster (7 km/h). If you need to quickly turn your hull on the spot towards flanking enemies, privilege the reverse gear (-6 km/h). The offroad mobility is good: the M19A1 reaches 17 km/h when fording, 19 km/h when driving uphill with some speed built-up and a mere 12 km/h uphill from a stop start. The wide tracks combined to the light weight of the vehicle grant the M19A1 a good mobility on hard (solid ground, roads) and soft terrain (mud, snow, sand). Light obstacles (fences and bushes) are not a problem but medium to large obstacles (posts, trees, concrete blocks and parked vehicles) will reduce your mobility: avoid them. |

Your ideal engagement window is between 1,000 and 1,500 m for aircraft.

Description
The Twin Gun Motor Carriage M19A1 is a rank III Japanese SPAA with a battle rating of 4.7 (AB) and 4.0 (RB/SB). It was introduced in Update "Direct Hit".
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.

The 40 mm gun stays reliably accurate until 1,000 m distance. Beyond 1,500 m the loss of accuracy becomes a real handicap. The shortness of the gun is mitigated by the high rate of fire and the fact that targeted aircraft are bigger than an average ground vehicle. Your ideal engagement window is between 1,000 and 1,500 m for aircraft. The high muzzle velocity of your shells grants you pretty flat firing trajectories and thus helps fire at fast-moving targets from a distance. As your shells weigh the same, your different belts offer the same firing arc.
The turret traverse speed is very high, allowing you to track any aircraft flying right by you. The gun elevation is also very good, almost allowing vertical fire. The depression angle is poor but not often used. The recoil is minimal and barely impacts your targeting. The reload time between clips is very short: under 1 second. While lacking a stabilizer, the M19 still can reliably fire on the move at targets under 700 m distance.
The gun overheats after in 20 seconds of uninterrupted fire and is forced into a cooldown phase of 10 seconds during which you can't shoot. To keep the gun from overheating, privilege firing by bursts instead of continuous fire with small pauses between shots. The overheating is displayed in-game by 4 red quadrants around your sight gradually filling up as you gun temperature rises. Always keep it from reaching the 3rd quadrant.

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.
Usage in battles
With the Dual 40 mm Bofors the M19 has an excellent weapon against bombers and armoured attackers. The ammo is limited though, so reserve the fire for certain hits. Against fighters, the same tactic should be applied. Compared to certain other SPAAs (ZSU-37, Wirbelwind, M13 MGMC, etc.), the M19A1 cannot be used as effectively in an anti vehicle role, so you should stay behind your allies and watch the skies for attacking aircraft. If contact with ground targets is inevitable however, aiming for the target`s cannon barrel or tracks is a good option. If flanking is available, take the opportunity and load some shells into their sides or rear. However be very careful, your crew members are exposed to machine gun fire and can easily be knocked out. This is a problem especially if it's coming from enemy aircraft, as they can also easily kill your crew. So take caution when using the M19 in an anti-vehicle role.
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".
Pros:
- Good gun
- Good on road mobility
- Heavy Anti-Air firepower
- Very short reload
Cons:
- Almost no armor
- Open topped
- Decreased mobility off-road
- Exposed ammo rack
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).
