The '''{{Specs|name}}''' ({{Annotation|四式十五糎自走砲「ホロ」|Yon Shiki Jūgo Senchi Jisōhō "Ho-Ro"}}) is an open-topped self-propelled gun with a short-barreled 150 mm howitzer, based on the [[Chi-Ha]]. Being pressed instantly into service on its creation, a dozen or so were shipped to the Philippines together with the newly formed 1st Self-Propelled Artillery Company. While it did see combat with several confirmed Sherman destructions, it was effectively used in close-quarter combat rather than as an artillery piece, firing at Shermans at 100-200 m range in smokey and low visibility scenarios, and repositioning on each shot. Arriving in Dec 1944, the last Ho-Ro squad served until knocked out in Mar 1945 with the remainder of the company fighting until the end in the mountains as regular infantry.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.65 "Way of the Samurai"]] along with the rest of the Japanese Ground Forces Tree. The vehicle, known by its full designation as the ''Imperial Japanese Army Type 4 15cm self-propelled gun Ho-Ro'' (Original Text: 日本語: 四式十五糎自走砲 ホロ), is an open-topped SPG with a short-barreled 150 mm howitzer, based on the [[Chi-Ha]] chassis and running gear.

The name "Ho-Ro" translates roughly to ''Gun Two'', or more properly, ''Self Propelled Gun Number 2''.<ref name="FTRecordJapaneseNames">Silentstalker. "Japanese Tank Nomenclature." For the Record. WordPress, 06 Dec. 2013. Web. 15 Jan. 2017. [http://ftr.wot-news.com/2013/12/06/japanese-tank-nomenclature/ Website]</ref>

Since its introduction in [[Update 1.65 "Way of the Samurai"]], the Ho-Ro has gained a reputation for being one of the most powerful howitzer-equipped SPGs in the game despite its low battle-rating, right up there with the beloved [[KV-2 (Family)|KV-2]]. It is capable of destroying or severely disabling any opponent it meets (or more often ambushes), even against top-tier vehicles, mainly due to its extremely effective high-explosive shell. This is balanced, however, by the shell's low velocity, forcing the player to lob the shell in an arc at their opponent even for a short distance, and the vehicle's light armour and limited gun traverse compared to other SPGs.

Since its introduction into War Thunder, the Ho-Ro has gained a reputation for being one of the most powerful howitzer-equipped SPGs in the game despite its reserve battle-rating, right up there with the beloved [[KV-2 (Family)|KV-2]]. It is capable of destroying or severely disabling any opponent it meets (or more often ambushes), even against vehicles in Rank V. This is mainly due to its extremely effective High-Explosive shell, however this is balanced by the shell's low velocity, in which the player must literally lob the shell in a arc at their opponent even for a short distance, and the vehicle's generally light armour and limited gun traverse compared to other SPGs.

The Ho-Ro is a fairly manoeuvrable SPG, and like many other open-topped vehicles, this is not one that should charge into the front-lines. Just like many of the other low-rank Japanese vehicles, it has no real armour protection from anything more than rifle-calibre MGs, and its ammo storage is literally a box mounted on top of the engine deck. The crew is very exposed, and the gun breech is mounted rather high on the chassis and can be easily knocked out. With this knowledge in mind, the Ho-Ro is best played by staying in the rear (but not distantly) of friendly tanks as short-range or point-blank artillery fire, along with finding hidden positions where it can attempt to be hull-down out of sight of the enemy.

Due to its low-velocity shell, the gun often needs to be aimed higher than the commander estimates when performing direct-fire onto a target, but this also allows the vehicle to lob shells from behind shallow hills, out of the sight from opponents that may be camping or pushing into friendly territory on the other side. Note however that because its HE shell is so powerful, it is '''''extremely risky to fire directly next to or very close to an enemy vehicle''''', as the light armour may not protect the crew, and the blast from the shell's explosion it will certainly deal damage to the vehicle itself. The gun, while powerful, cannot traverse very far to either side and its depression is actually depressing (-5°), so in order to fire on tanks that are outside of the arc of the gun's horizontal traverse or down a hillside, the entire hull must be traversed as well. The recoil of the gun is also an issue, as it throws the vehicle backwards rather severely (just like the M-56 Scorpion), which means it loses target acquisition every time it fires.
 
  
−
One interesting note is the pintle-mounted MG on the roof, which has good elevation and a much wider range of horizontal fire than the main gun, which can be useful on spotting enemy tanks for team-mates or dealing with [[:Category:Anti-aircraft_vehicles|SPAA]]s that have exposed gun-crews. However, it has a slower rate of fire than most other rifle-calibre MGs and its magazine capacity is pitiful. In conclusion, the Ho-Ro is a very defensive vehicle suited to supporting friendly tanks and ambushing the enemy on paths where they may attempt to flank around the map.

The Type 4 Ho-Ro was a Self Propelled Gun developed by the Imperial Japanese Army based off of the German Grille series. It was developed off the Type 97 Chi-Ha chassis and used a 150-millimetre Kruppe gun, considered outdated by 1942. It was used to combat American forces. Only few were made, and out of those few 8 were sunk with a Japanese ship somewhere in the Pacific. Usually deployed in groups of 4, it was used in the Philippines during late 1944 and then used in ones and twos on Okinawa, with a somewhat great affect. It was ineffective due to its 3 degrees of gun swing and 30 degrees of depression because of the gun mounts design. That gave it a small firing distance of 6,000 meters. It also could only fire 5 shells per minute because of the breechloader.

Description

The Type 4 Ho-Ro (四式十五糎自走砲「ホロ」) is an open-topped self-propelled gun with a short-barreled 150 mm howitzer, based on the Chi-Ha. Being pressed instantly into service on its creation, a dozen or so were shipped to the Philippines together with the newly formed 1st Self-Propelled Artillery Company. While it did see combat with several confirmed Sherman destructions, it was effectively used in close-quarter combat rather than as an artillery piece, firing at Shermans at 100-200 m range in smokey and low visibility scenarios, and repositioning on each shot. Arriving in Dec 1944, the last Ho-Ro squad served until knocked out in Mar 1945 with the remainder of the company fighting until the end in the mountains as regular infantry.

Since its introduction in Update 1.65 "Way of the Samurai", the Ho-Ro has gained a reputation for being one of the most powerful howitzer-equipped SPGs in the game despite its low battle-rating, right up there with the beloved KV-2. It is capable of destroying or severely disabling any opponent it meets (or more often ambushes), even against top-tier vehicles, mainly due to its extremely effective high-explosive shell. This is balanced, however, by the shell's low velocity, forcing the player to lob the shell in an arc at their opponent even for a short distance, and the vehicle's light armour and limited gun traverse compared to other SPGs.

Usage in battles

The Ho-Ro is a fairly manoeuvrable SPG, and like many other open-topped vehicles, this is not one that should charge into the front-lines. Just like many of the other low-rank Japanese vehicles, it has no real armour protection from anything more than rifle-calibre MGs, and its ammo storage is literally a box mounted on top of the engine deck. The crew is very exposed, and the gun breech is mounted rather high on the chassis and can be easily knocked out. With this knowledge in mind, the Ho-Ro is best played by staying in the rear (but not distantly) of friendly tanks for short-range or point-blank artillery fire, along with finding hidden positions where it can attempt to be hull-down out of sight of the enemy.

Due to its low-velocity shell, the gun often needs to be aimed higher than the commander estimates when performing direct fire onto a target, but this also allows the vehicle to lob shells from behind shallow hills, out of the sight from opponents that may be camping or pushing into friendly territory on the other side. However, because its HE shell is so powerful, it is extremely risky to fire directly next to or very close to an enemy vehicle, as the light armour may not protect the crew, and the blast from the explosion it will certainly deal damage to the vehicle itself. The gun, while powerful, cannot traverse very far to either side, so to fire on tanks that are outside the arc of the gun's horizontal traverse, the entire hull must be traversed as well. The recoil of the gun is also an issue, as it throws the vehicle backwards rather severely, which means it loses target acquisition every time it fires.

One interesting note is the pintle-mounted MG on the roof, which has good elevation and a much wider range of horizontal fire than the main gun, which can be useful on spotting enemy tanks for teammates or dealing with SPAAs that have exposed crew members. However, it has a slower rate of fire than most other rifle-calibre MGs and its magazine capacity is pitiful. In conclusion, the Ho-Ro is a very defensive vehicle suited to supporting friendly tanks and ambushing the enemy on paths where they may attempt to flank around the map.

Pros and cons

Pros:

  • 150 mm short barreled howitzer
    • Low velocity and high arc allows to fire over hills and cover
    • High TNT filler
      • Ability to destroy any tank
      • Can cause sufficient indirect splash and shrapnel damage on non-direct hits
  • Roof-mounted LMG for self-defence against open tops/trucks
  • Fair manoeuvrability for a self-propelled howitzer
  • Good gun depression

Cons:

  • Thinly armoured
    • The extreme blast radius of the shell can destroy the vehicle itself at close range
    • Gun crew is exposed from the rear
  • Additional ammo rack is a rather exposed box on top of the engine
  • Massive recoil causes the vehicle to be launched backwards after firing, requiring aiming adjustment after every shot
  • Standard Japanese LMG with limited ammo
  • Tall silhouette makes easy to spot

History

The Type 4 Ho-Ro was a Self Propelled Gun developed by the Imperial Japanese Army, based off the German Grille series. It was developed off the Type 97 Chi-Ha chassis and used a 150 mm Krupp gun, considered outdated by 1942. It was used to combat American forces. Only a few were made, and out of those few, 8 were sunk with a Japanese ship somewhere in the Pacific. Usually deployed in groups of 4, it was used in the Philippines during late 1944 and then used in ones and twos on Okinawa, to a somewhat great effect. It was ineffective due to its 3 degrees of gun swing and 30 degrees of depression because of the gun mount's design. That gave it a small firing distance of 6,000 m. It also could only fire 5 shells per minute because of the breech-loader.
