A long range Colonial mobile artillery used to lay siege to fortified positions.
— In-game description
The 120-68 “Koronides” Field Gun (also known as the Field Artillery, or 120mm push gun) is a ColonialField Weapon equipped with a 120mmartillery cannon designed to engage enemies at a long distance and destroy fortifications through indirect fire. It must be deployed to be able to fire
The 120-68 “Koronides” Field Gun doesn't operates like most Field Weapons due to it being an artillery piece, with it providing long-range support by hammering enemy positions and structures. Unlike its Warden counterpart, it has less range, and security, but makes up for this with mobility/flexibility. Its mobile nature makes it easier to change firing positions, especially for shifting frontlines, when enemy positions are destroyed and artillery needs to move up with them.
It's biggest weakness is the fact that it can be stolen by enemy soldiers, since it's classified as a vehicle and not an emplacement (which cannot be interacted by the enemy faction). As such, it is of great importance to place defenses around your artillery to avoid enemy infantry from attacking your position and potentially destroying or stealing them.
Although its mobile, it should follow standard artillery defensive precautions, and set up a defensive perimeter around it to protect it from enemy infantry, vehicles, or counter-artillery.
All push guns, by their nature, are one of the most vulnerable vehicles in the game in terms of crew protection. They are exposed to the enemy, making them susceptible to all enemy fire. Due to push guns requiring both crew members to move them, the death of a single crew member could result in the push gun being lost. Due to this, it is recommended to only lock the gun when it looks like enemy infantry are going to overwhelm you and can steal it. This tactic is vital if a push gun is decrewed, as it allows a friendly soldier to quickly man it and drive it back to safety.
Push guns have a visibility mechanic, which allows it to operate differently compared to regular vehicles. Similar to infantry, they are affected by vision, meaning their movements cannot be seen unless it is within your line of sight. Due to this, they can hide behind structures, or even bushes (depends on how big the bush is). It's also affected by the time of day, with nighttime making it possible for push guns to become invisible to the enemy if you're far enough from them. Keep in mind that if the enemy decides to illuminate your position, this will expose it until the flare dies out. The push gun's position will be exposed anyway if the crew decides to fire its main armament.
Like all artillery equipment, shells can be quickly submitted into them without accessing their inventory
While this can be done for all vehicles, it should only be done if they can carry/use large items
Equip the shell and walk up to the vehicle

Both factions originally had Field Artillery, however the Warden's Field Artillery was removed, as the game's development leaned more towards asymmetrical weaponry (i.e. both sides having slightly different weaponry, but functioned in more-or-less the same way).
Despite the 120-68 “Koronides” Field Gun being the counterpart to the Warden Huber Lariat 120mm, due to their design, they are on different Tech Trees
The Colonial one is in the Vehicle Tech Tree, while the Warden one is in the Weapons and Structures Tech Tree
In Update 1.54 ('Naval Warfare'), the 20-68 “Koronides” Field Gun recieved multiple changes.
Towing was added, which allowed certain vehicles to "hitch" certain vehicles (mainly Field Weapons), allowing them to be moved without the need of larger equipment, such as Flatbed Trucks and Cranes.
It was reclassified as a Heavy Chassis Field Gun, which meant it needed to be deployed in order for the Field Artillery to be fired.
It received a limited traversal arc, which was changed from its static firing arc to accommodate its new deployment method, which prevented the Field Artillery from making small firing adjustments (requiring the crews to undeploy it, then redeploy it)
