The 2S9 Sochor is a self-propelled, heavy artillery vehicle used by both Mediterranean and Pacific CSAT forces.

OverviewEdit

  • Role:
    • Indirect fire support
« The 2S9 Sochor is a lightly armored self-propelled artillery piece used by the OPFOR army. It's based on the T-100 chassis and fires 155mm projectiles. The T-100 chassis interior has to be heavily modified to allow support for the 155mm cannon with auto-loader. The modification paid off and several Asian countries are now in the process of modernizing their heavy artillery division with the 2S9.

Design Edit

Armed with a 155mm howitzer cannon as its primary weapon, the 2S9 is a powerful gun-based fire support vehicle that is capable of firing a mixture of high-explosive, smoke, cluster, and even precision guided shells on targets at extreme distances.

The standard loadout of the 2S9 gives it 32 rounds of high-explosive (HE) shells for the main gun. In addition to the standard high-explosive shells, 6 different sub-munition types are also available, forming a total of 24 more shells that can be loaded. These include:

  • 2 rounds of infrared-guided (heat seeking) shells
  • 6 rounds of scatter shells that can cover an area with anti-personnel (AP) mines
  • 2 rounds of cluster shells that can saturate an area with a hail of explosive fragments
  • 6 rounds of deployable white smoke shells that can cover the impact zone instantly in a thick cloud of smoke
  • 2 rounds of laser-guided shells
  • 6 rounds of scatter shells that can cover an area with anti-tank (AP) mines

The externally mounted RCWS comes pre-loaded with a single 500 round belt of 12.7mm ammunition, and 96 rounds of high-explosive 40mm grenades.

The 2S9 shares the same chassis as its MBT parent, which gives it the level of protection of a tank while having the same high degree of manoeuvrability and speed of the T-100. For self-defence, the 2S9 also has an RCWS turret fitted on top that is armed with a dual-mount 12.7mm heavy machine gun and 40mm automatic grenade launcher.

Despite having the same capabilities as the T-100 in terms of handling, it also shares the same vulnerabilities as well, such as having an exposed rear engine while lacking the heavy armour of its NATO counterpart. It also cannot adequately defend itself against enemy threats that get too close without having to resort to attacking in direct fire mode, so having friendly units providing escort is critical.

The 2S9 has a seating capacity of three personnel for a crew consisting of the driver, gunner and commander.

Camouflage Edit

  • Hex: Following a light tan/dark tan/dark green cell pattern camouflage, this is used in forested, grass plains, and desert environments.
  • Green Hex: Following a dark tan/light green/dark green cell pattern camouflage, this is used in heavily forested and tropic environments.

Capabilities Edit

It fires all 32 HE rounds in four minutes and 12 seconds, averaging at just under 8 seconds per shot. This makes its fire rate considerably slower than the Mk6 Mortar, although its damage and blast radius per shell is significantly greater.

The Sochor has five range modes available for firing:

  • Close range: 826 to 2,415 meters (ETA 30-22 seconds)
  • Medium range: 2,059 to 6,021 meters (ETA 48-35 seconds)
  • Far range: 5,271 to 15,414 meters (ETA 78-56 seconds)
  • Further range: 14,644 to 42,818 meters (ETA 130-96 seconds)
  • Extreme range: 22,881 to ~67,112 meters (ETA 162-117 seconds)

Overlaps occur in the following ranges:

  • 2,059-2,415 meters (Close and Medium)
  • 5,271-6,021 meters (Medium and Far)
  • 14,644-15,414 meters (Far and Further)
  • 22,881-42,818 meters (Further and Extreme)

Unfortunately, this means that when simply using the built-in artillery computer, the Sochor can only perform MRSI strikes in narrow nearby bands, or in the large band beyond ~23 km. It is also unable to have more than two volleys landing on the same target at the same time.

Note however that the built-in computer tends towards using low-angle trajectories. The Sochor is capable of firing at up to an 80 degree angle from flat ground. This means that it is technically capable of getting multiple volleys to land on the same target simultaneously, but it would require manual calculation of the appropriate trajectories, or the use of spreadsheets or third-party applications.

Manual firing Edit

By default, the turret can be manually raised and lowered with the page up and page down keys. For precision aiming, the rate of adjustment can be slowed by holding down the shift key (by default) while aiming up or down.

It is also possible to adjust range mode without the artillery computer, though this is more difficult. By default, using the F key will cycle through the different range modes, from Close range through to Extreme range and back to Close. It is also possible to bind a key to go from longer ranges to shorter ranges, though there is no default binding for it (Weapons > Previous weapon). Although there is no indicator without the artillery computer to determine which firing mode is currently active, it is possible to work it out by using the rangefinder to point at an object within Close range (826-2,415 meters) and cycling through the firing modes until the red X on the crosshair goes away, indicating you've returned to Close range.

Trivia Edit

  • While the Sochor is not specifically based on a real-world design, the idea of combining an artillery turret (which is also shared with the M4) with a tank chassis is similar to that of the real-life "2S35 Koalitsiya-SV".
    • Though the range of the Sochor is further than the size of any of the official terrains, it is similar to the range of the real-life 2S35, with both being able to strike targets at a maximum distance of roughly 40 km.
  • As with the Sochor, the 2S35 utilises a self-propelled artillery gun mounted on a chassis derived from the "T-90" MBT.
