The {{PAGENAME}} 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 {{PAGENAME}} has an open-topped turret, gun servants are also very exposed to MG fire, artillery strikes and plane strafings.

The 40 mm Bofors 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. The ideal engagement window is between 1,000 and 1,500 m for aircraft. The high muzzle velocity of shells grants pretty flat firing trajectories and thus helps fire at fast-moving targets from a distance. As the shells weigh the same, the different belts offer the same firing arc.

'''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.

With the Dual 40 mm Bofors the M19 has an excellent weapon against [[:Category:Bombers|bombers]] and [[:Category:Attackers|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 M19 cannot be used as effectively in an anti-vehicle role, so stay behind your allies and watch the skies for enemy aircraft. If contact with ground targets is inevitable however, aiming for a targets' cannon barrel or tracks is a valid 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 if using the M19 in an anti-vehicle role.

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".

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:

  • 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 M19 cannot be used as effectively in an anti-vehicle role, so stay behind your allies and watch the skies for enemy aircraft. If contact with ground targets is inevitable however, aiming for a targets' cannon barrel or tracks is a valid 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 if using the M19 in an anti-vehicle role.

Pros and cons

Pros:

  • Heavy anti-air firepower
  • Unsynchronized cannons increase the chance of a hit
  • Powerful 40 mm HE shells, a direct hit can decimate/critically damage aircraft
  • AP shells have 72 mm of penetration at point-blank, enough to go through the lower side plate of a Tiger I
  • AP shells maintain a reasonable amount of penetration at range
  • Stock belt is effective at dealing with light tanks and other SPAA, and it also breaks tracks and cannon barrels easily
  • Reloads in just 0.6 seconds
  • Inherits the excellent mobility of the M24

Cons:

  • Open topped. HE shells, artillery and aircraft can cripple this vehicle with ease
  • Little armour. Most vehicles from Rank II onwards can penetrate it frontally
  • Exposed ammo rack. Experienced players will just shoot there and ruin your day
  • Compared to other SPAA at the same rank, poor anti-vehicle performance. Will only be effective at anti-air duties
  • 40 mm cannons still have a lower rate of fire compared to their counterparts
  • Some heavy tanks you will see are immune to your AP shells at any angle and range
  • AP shells are solid shots and don't cause a lot of spalling
  • Decreased mobility off-road

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.
