Description
The ▄Obice da 155/23 Semovente M109G is a rank IV Italian tank destroyer with a battle rating of 6.0 (AB/RB/SB). It was introduced in Update "Kings of Battle".
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.
Armour type:
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | ___ mm | ___ mm Top ___ mm Bottom |
___ mm | ___ - ___ mm |

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.

History
The story of the M109 begins during the late stages of the Cold War, it would be designed due to a need from the American army to completely replace their aging fleet of M44 self-propelled howitzer. The main objectives for the new and improved replacement were for it to be somewhat mobile and have a bigger calibre. Initial prototypes for the M109 would see it armed with a 105 mm cannon, but would later be changed to a 155 mm. It was also chosen to equip the vehicle with a diesel engine which, although it would prove to give less output, was much more reliable so breaking down would not become a common occurrence. It would first officially enter service in the American army by 1961, and would prove to be quite effective on the battlefield.

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