The artillery was a long-range fire support system, utilized to augment building destruction capability of the side employing it. However, the artillery is very weak compared to other vehicle units so protection is needed.
The damage is too extensive!
Artillery units (Red Alert) has been marked for cleanup.
Early artillery was the M110 howitzer, a tracked, lightly armoured vehicle with a single 155mm cannon. The gun was in a fixed position and the entire vehicle had to be rotated to acquire different targets.
Later artillery, in contrast, looked like a platform for a massive cannon which was affixed at the back of the weapon. Small outrigger legs deployed and stabilized the weapon while it was being deployed, balancing and stabilizing it against the recoil of the massive cannon.
Second World War
During the Second World War between the Allies and the Soviets, the Allies used 155mm Self Propelled Howitzers. Howitzers were smaller units (as compared to tanks) that fired powerful explosive charges. Allied commanders generally used it to weaken Soviet forces before they reached the main line. Although it might have seemed effective to use against Soviet defenses, this was not advisable, as Tesla coils had even greater range than Artillery pieces, and enough power to reduce them to dust in one blast.
During the war, Howitzers was generally used as a highly effective and long range way to deal with infantry and soften up enemy formations, although because of its lack of health, slow speed, and very slow turn rate, it was very vulnerable to enemy fire, particularly by tanks. Allied commanders generally used it as a second-line unit designed to support medium tanks and light tanks. It was replaced for it has weak armour with various artillery including the Prism Tank and the Athena Cannon.
The Soviets have the V2 rocket launcher to level base defenses. It has considerable long firing range but requires large amount of time to reload its rocket. The rocket is more powerful and has large area of destruction.
Third World War
By the time of the Third World War the Soviet Union began using V3 Rocket Launchers. The V3 was basically an upgraded version of the V2 Launcher used during Great World War II. Although somewhat fragile and inaccurate, escorted groups of V3 Launchers could quickly level a large base from a safe distance, as various suffering Allied commanders can attest. Later in the war, Soviet naval forces developed the fearsome Dreadnought to be a naval equivalent. The Soviets also developed the Siege Chopper, and used particularly against Yuri forces during the Psychic Dominator Disaster. When it landed, it deployed a powerful large long-range artillery piece that could quickly bring ruin to enemy bases.
The Allies somewhat lacked in long-range capabilities in the battlefield until the development of the devastating Prism Tank during the course of the War. Prism Tanks could fire high-intensity and highly-destructive beams of light from a very long range. These fast, lightly-armoured vehicles were effective against all land targets except for the most heavily armoured tanks, and could annihilate a base in seconds.
War of the Three Powers
The Allied Athena Cannon determines a target's position for an Allied satellite-based solar cannon to do long range attacks. The Allied navy uses Aircraft Carriers to accurately attack enemy bases with a squadron of drone bomber planes. After the war, the Pacifier FAV was developed, having a longer range than the Athena Cannon, and is made available earlier, but have a lower accuracy.
The Soviet army still advance its rocket series into V4 rockets. Despite of its main rocket with fixed target system, the rocket launcher can also switch into firing scatter shells for wider area of destruction, useful for enemy units. Soviet Dreadnought can fire larger series of V4 rockets that will fight to the last man and rocket. Unlike previous V-class rockets, V4s cannot be shot down.
The Empire's ground forces utilize Wave-Force Artillery that is devastating against any ground enemy, but it requires long energy charging time for best result. In the Imperial navy, the Shogun Battleship is a battleship with long range bombardment capability for supporting any Imperial invasion.
