History
Assault ships are smaller mobile units generally associated with quick offensive action. The Roil-class of craft were designed and built with this intent following the conventional doctrine of Pre-War assault doctrines of warfare. As such, these ships are relatively well armed compared to their human counterparts; carrying both point defense laser cannons and a primary EM cannon in place of homing missiles that the Four Nations Alliance tended to use.

Roils could easily out-fight matching classes during their time due to superior mobility and the ability to use their laser cannons as point-defense of their own vessel. These capable units; however, sacrificed much of the ship's armor to house the power units needed for agility, better energy shielding, and firepower.

The War and Early Combat Roles
Following the start of the war sparked by the Battle of the Gosroth, it appeared the assault ships would dictate the pace of the war, given that a patrol ship had not succeeded against a wolfpack of 10 assault ships. The Roil-Class saw action primarily during the Battle of Skaresh, albeit a stalemate action, mobility doctrine held in the Laburec and it would continue to see mass production.

Operation Phantom Flame
During Operation Phantom Flame, the then Three Nations Alliance exploited a limitation of the Roil-class against projectile weapons; specifically mines. With the use of long range and separation mines, the point-defense of Roil-classes proved inadequate to deal with these small mobile weapons, which proved horrifyingly effective during the 2nd Battle of Aptic. The assault doctrine needed to be revisited, since it appeared that the Roil-Class, while capable of out-pacing enemy ships of the same type in a brawl, could not withstand pitch battle in the defense of fixed positions.

For this purpose, the Laburec revisited its production orders for ships since the Commander-in-Chief Abriel Dusanyu of Operation Phantom Flame found his fleets ill-equipped to deal with battleship and patrol-ship heavy enemy fleets. From this point on, the Laburec would emphasize production of larger patrol ships and ships of the line; including older classes as well. The classes featured prominently to fill this primary roll for a time would be the Byrsh-Class, Lauth-Class, and Kau-Class.

Operation Hunter
New variants to improve the powerplants and replace the losses of Aptic had been produced; however, mass production of the Roil-class now entered phases of joint production of the upcoming Caubh-Class, a medium frigate that balanced the ability to take damage, improved point-defense, and overall firepower. Roils were now to compliment heavy fleets and attack vessels like the Caubh to force the enemy to engage in a fluid battlefield.

The Roil-class saw moderate action at the spearhead of the 4th Fleet Hunter commanded by Admiral Neres Bebaus.

Operations Twin Thorns and Snow Crystal
The Roil-class continued to see combat service jointly with the Caubh-class. At the Battle of Kemal, these ships devastated enemy units when used in conjunction with the new medium attack ships. Admiral Rekef, despite taking some time to penetrate the enemy defense with lighter ships maintained damage parity and utilized his mobile fleet to ultimately achieve victory.

During Operation Snow Crystal, the Roil-class production would take a blow due to new enemy offensives into Kryb and Lakfakalle. The standing units continued to fight, though replacement Roils would become increasingly rare after this point in the war.

Variant

 * Roil-Class Command version (better communication and command equipment but otherwise no difference) The command section was made more voluptuous to house the additional equipment and the lower fuselage was widen to house more antennas.


 * Roil-Class II version sported an additional two rotary laser turrets that featured four barrels housed in the dome-like fixture emplacement. The emplacement on the ship itself would rotate to aim the next barrel to fire upon the enemy.

Difference and Changes between Novel and Anime

 * Senki I novel: 1 anti proton cannon, 2 (anti proton) turrets, hangar
 * Bots I anime: 1 anti proton cannon, 2 barreled laser turrets, 2 hangars
 * Bots I movie anime: 1 anti proton cannon, 2 barreled laser turrets, 2 dual-cannon laser turrets, 2 hangars
 * Bots II: 1 anti proton cannon, 2 barreled laser turrets, 1 hangar (this was probably done to fix the ship's size)
 * PC game: 1 anti proton cannon, 2 barreled laser turrets
