G15x Medium Howitzers - itc-addons/ITC_Land_Systems GitHub Wiki

ITC Land Systems includes a number of features which add significant improvements to the vanilla self propelled howitzer (SPH) systems for player use.

As part of the mod we have prepared variants of the vanilla SPH systems with these features already implemented, allowing for the use of the existing vanilla Arma SPH systems or our own variants. This is important as our own systems are not designed for use by AI.

The following are the included SPH systems derived from the existing Arma 3 SPHs.

  • M4 mod. 0 Sholef 2 - 155mm
  • 2S9 mod. 0 Sochor 2 - 152mm

G15x Ammo Handler & Autoloader

The G15x Ammo Handler & Autoloader allows the gunner to load G15x munitions with their full functionality.

Basic Usage

  1. Use of this is fairly self explanatory. The gunner first selects the desired munition from the list on the left of the dialog. They can then set the desired fuze settings by selecting the fuze mode from the dropdown box and entering the required values in the appropriate text fields.
  2. Once the desired settings have been input the gunner then clicks APPLY SETTINGS to apply the settings to the autoloader. Note: The gunner cannot apply settings while loading a shell, unloading a shell, or with a shell in the breach.
  3. Once the settings have been applied the shell can be loaded with the load button, once loaded this can be fired as normal from the gunner's sight. Firing will start the autoloader, if a round count of 1 or more has been set it will continue to load until the specified number of shells have been fired. If a round count of any value less than 1 is set the autoloader will continue to load until a shell is unloaded.

Unloading a shell at any point essentially cancels the autoloader queue, regardless of round count specified, and will allow the gunner to set new settings.

G15x Munitions

ITC Land Systems adds a number of improvements and improved functionality to the available ammunition for 155mm and 152mm howitzers in Arma 3. The following munitions are available in both calibers.

  • G15x HEX - High Explosive - Fuze Modes: Proximity, Point Detonate, Delay, Time
  • G15x SMO - Smoke - Fuze Modes: Time
  • G15x ICM - DPICM - Fuze Modes: Time
  • G15x MAP - Mines Anti-Personell - Fuze Modes: Time
  • G15x MAT - Mines Anti-Tank - Fuze Modes: Time
  • G15x ILL - Illumination - Fuze Modes: Time
  • G15x LGM - Laser Guided Munition - Fuze Modes: Proximity, Point Detonate, Delay
  • G15x PGM - GPS Guided Munition - Fuze Modes: Proximity, Point Detonate, Delay

We have also created a specialist Anti-Armour munition called EXTRA, this is available only for 155mm systems at the moment.

  • G15x EXTRA - Parachute Deployed Anti-Armour Guided Munition - Fuze Modes: Time

G15x Sights

We have created three information displays to provide player gunners useful information regarding gun alignment and autoloader settings and status. These are viewed as any other vehicle weapon sight is in arma.

For Addon Makers

These new displays are added using the turretInfoType config setting on the same turret as the gun.

Basic Gunner Sight: ITC_Land_RscGunnerSightSPH

Shown above. This is intended to be used with the standard Arma 3 mortar sight model. It displays the gun's current azimuth and quadrant, as well as the current fire mission azimuth and quadrant if set manually or through the vehicle CFCS. It also includes a readout of the current autoloader settings and status, as well as a rounds fired count if a round count has been set.

Alternate Gunner Sight: ITC_Land_RscAltGunnerSightSPH

This is intended to be used for adding compatibility with 3rd party mods and should fit with most custom sight models and vehicles that do not use the Arma 3 mortar sight model. It displays the gun's current azimuth and quadrant, as well as the current fire mission azimuth and quadrant if set manually or through the vehicle CFCS. It also includes a readout of the current autoloader settings and status.

MLRS Gunner Sight: ITC_Land_RscGunnerSightMLRS

This is intended to be used for MLRS or SPH systems using the mortar sight model but without the G15x ammo handler and autoloader. It displays the gun's current azimuth and quadrant, as well as the current fire mission azimuth and quadrant if set manually or through the vehicle CFCS.

In-game Logistics/Resupply and Notes for Mission Makers

Adding extra ammunition to an SPH

Due to the way the ammohandler works, the magazines compatible with the vehicle weapon are not the ones that need to be added to the vehicle. These must be added using the addMagazine or any variant used for adding vehicle magazines to a vehicle. Note: These do not go in vehicle cargo. Below is a list of vehicle magazine classnames for use with the ammohandler and the included SPH systems.

  1. 155mm Munitions
  • itc_land_g155hex - High Explosive
  • itc_land_g155smo - Smoke
  • itc_land_g155ill - Illumination
  • itc_land_g155icm - DPICM
  • itc_land_g155map - Mines Anti Personell
  • itc_land_g155mat - Mines Anti Tank
  • itc_land_g155pgm - GPS Guided Munition
  • itc_land_g155lgm - Laser Guided Munition
  • itc_land_g155ext - EXTRA
  1. 152mm Munitions
  • itc_land_g152hex - High Explosive
  • itc_land_g152smo - Smoke
  • itc_land_g152ill - Illumination
  • itc_land_g152icm - DPICM
  • itc_land_g152map - Mines Anti Personell
  • itc_land_g152mat - Mines Anti Tank
  • itc_land_g152pgm - GPS Guided Munition
  • itc_land_g152lgm - Laser Guided Munition

In game logistics and resupply

We recommend using the ACE3 Rearm Framework with these vehicles, using the "Specific Magazines" method and dedicated resupply vehicles for the firing group.
