Initially intended to provide a mobile platform for cumbersome field weapons, the T13 “Deioneus” Rocket Battery is a lightweight tankette fitted with a nine-barrelled rocket artillery. This unique battery is configured for incendiary rockets to be launched at range while maintaining high maneuverability between deployments.

— In-game description
The T13 “Deioneus” Rocket Battery (also known as a Rocket Tankette, or Rockette) is a Colonial Rocket Artillery Tankette. It is equipped with a Rocket Battery for 4C-Fire Rockets.
The T13 “Deioneus” Rocket Battery has 1350 HP and is disabled under 30% health. It has "Heavy Armor" resistance: it can soak small arms fire, shrapnel, and 12.7mm machine guns, and it is immune to Flamethrowers. But it won't last long when faced with heavy explosives or anti-tank weaponry. It has subsystems that have a chance to be disabled by heavy explosives and anti-tank weaponry if hit specifically: Tracks: 30% (Anti-Tank Mines always disable them). It has Tank Armor. With it, in best case scenario, penetrating projectiles only have a 55% chance of penetrating and doing damage. That chance goes up quickly if the armor is worn or if it is shot from up close, or on the side or rear from a direct angle,or with ammo that has penetration bonuses. It takes 150 Basic Materials to fully repair it from 1% to 100% health with a Hammer. Its health, subsystems, and Tank Armor can be instantly repaired at a Garage for 100 Basic Materials.
Rocket Barrage
Rocket batteries excel at burst damage, compared to regular artillery which is suited for sustained barrages. Due to the rocket's high dispersion, they are most effective when attacking in groups, as the large volume of rockets increases the chances of hitting targets. Since rocket vehicles can be reloaded prior to their actual deployment, they can be used in hit-and-run tactics: drive to the location, fire all rockets, and evacuate before any enemy responds.
4C-Fire Rocket batteries have relatively low damage and rely mostly on their ability to set most structures on fire. Attacking with a large volume of rocket at once is paramount to increase the chances of starting self-sustaining fires that will slowly destroy structures and spread to nearby structures. Fire also prevent the repair of structures which has good synergy with conventional artillery. A single hit from a rocket can start a low level fire which will burn for at least 5 seconds, preventing all repairs for that time.
With their extreme range, only surpassed by Storm Cannons, 4C-Fire Rocket batteries operate slightly beyond the range of regular artillery. They can fire across wide rivers or over large mountains and hit deep in the enemy's defense lines. However, rockets cannot be fired across Region borders unlike 300mm. Rockets also have a lower "angle of attack" than regular artillery. Taller structures like Town Bases are easier to hit but targets obscured by hills or other structures are harder to hit.
Defenses
The T13 “Deioneus” Rocket Battery's armor and health can help it survive the retaliatory fire from the enemy Artillery Garrison it hits (7 direct hits to disable, 9 to kill).
When not used in a hit-and-run, the T13 “Deioneus” Rocket Battery should follow standard artillery defensive precautions despite its mobility and armor. A defensive perimeter must be present around it to protect it from enemy infantry, vehicles, or counter-artillery.
Spotting
The extreme range of rocket platforms means the spotter has be far away and close enough to the targets to determine the effect of the wind and the effect of tall obstacles. Determining the correct aim can be a slow and tedious process. This can be sped up using a Wind Sock. Aim adjustment is more tedious for rocket batteries on Colonial vehicles since it requires the vehicle to undeploy, move, and redeploy.
Tips
Unlike most artillery platforms, rocket vehicles can be operated by one crew member acting as both driver and gunner. The only downside is that loading rockets alone takes much longer than with two players.
Do not package a loaded rocket vehicle as this will delete all rockets in the battery.
Trivia
The T13 “Deioneus” Rocket Battery is the first Colonial vehicle to use 4C-Fire Rockets
It was briefly possible for both sides to produce them, however that was shortly removed after War 96 ended (the first war when 'Inferno' released).
They were made able producible by both factions in Update 1.53, as both sides now had vehicles that used them.
The name “Deioneus” is used by many individuals in Greek mythology - one of whom was pushed into a bed of coals by Ixion.
