Tactical analysis

 * Let them come: The Stark "Ayra" is an advance MBT of Fortress Battalion. And while its rocket pods is effective against infantry and light vehicles its main weapon is its heavy railcannon held between it that can break apart any armor, and in the event it survives the blast tends to leave its crew reeling for another shot, while dual rocket pods on its sides excel at taking down lighter vehicles. But the recoil and power means it must be secure itself to the ground before firing.
 * Break them: In the event they face against a large force they can also fire two high explosive "needle" rockets
 * I'm charging it as fast I can: But all of this comes with a few weakness. The most noticeable one is that its armor and autocannons power is rather underwhelming while it takes a few precious seconds to set up its railcannon, and it also takes time for the cannon to charge up and has minimum range, though the latter is remedied by its rocket pods, its weaponry is pretty much useless against infantry and structure. And, above all else, lacks any defense against air, relying on anti-air units to cover them
 * Keep firing: Veteran crew tends to disregard the proper charging procedure in favor of charging their railcannon, even when no enemy is sighted, at full power before keeping it just below risk of overload. Though dangerous to the inexperienced it drastically increases the railcannon fire rate and range. Alongside this the driver cabin gains a remote turret holding a HMG, giving them some defense against infantry when stationary, and the turret allowed to hold two additional needle rockets

Ace upgrade
Railcannon will now charge up, even when its not attacking, can use the rocket ability two more times, and increase range and rate of fire and gains a co-axial HMG.

Trivia

 * The Ayra is based of the Sherman firefly tank. While its name is based of Arya Stark
