Rochev
Contents
Description
The Rochev was the name given by the IDF to the M109 self-propelled howitzer gun that was introduced before the Yom Kippur War of 1973. This name was specifically given to the variants between the M109 and the M109A2. During this war only one battalion was equipped with these guns, the tiger battalion. This battalion lost almost his entire B battery during the first days of the war. The most common version of this vehicle was the M109A1 that featured a longer barrel and various improvements with a maximum range of 18100 metres. The A2 variant provided increase reliability availability and maintainability and safety characteristics for the crew as well as enhanced operational capabilities. The rammer and the recoil mechanism were improved. The engine and the hydraulic systems were improved in the bustle was designed to carry an additional 22 rounds of ammunition. A new M185 cannon was installed in the M178 gun mount. Most of differences between all of these variants were internal and especially regarding the shell loading system.
It was introduced in Update "Air Superiority". The M109A1 Rochevis very similar to the normal M109 in the Israeli tech tree. It features a new cannon specifically the M185 cannon that is of the same 155 millimetre calibre of the regular gun of the M109. This means that the penetration is not improved but the shows have actually a longer range and the higher speed so aiming is much easier with this vehicle. The addition of more HMG's and the like machine gun increases the ability of this vehicle to deal with close air support and light attack planes like the P51 and BF 109 that can be relatively easily destroyed with a precise shot of heavy machine gun. Still the tank has relatively poor survivability and the reload time is quite large however the high explosive shell is powerful enough to deal with most MBTs if aimed properly. No need to mention that like tanks like the AML-90 and the AMX-13 stand very little chance against your high explosive shells since their lack of farmer make them extremely vulnerable to this kind of projectiles.
General info
Survivability and armour
Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Armaments
Main armament
Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
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".

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.
