Kalran: Tales of the four nations/Stark "Cathlyn"

"Rocket artillery here."

Tactical Analysis

 * Rockets red glare: The Stark "Cathlyn" is Able Battalions artillery. Mobile and armed with an array of rockets, the Cathlyn can devastate the enemy with a steady barrage of rockets or hammer them with a withering volley
 * Guns blazing: The Cathlyn is also rather tough, being based off a tank hull, and is armed with a pair of burst firing machine guns, allowing them to pick off small groups of infantry
 * Fire everything: The Cathlyn is capable of continuously pounding the enemies with a steady volley of rockets capable of suppressing large numbers of infantry, if they weren't shredded by shrapnel, and creating hundreds of tiny craters in the ground, slowing enemy movement. Alternatively, the Cathlyn can launch all of its rockets at once, decimating infantry and stunning vehicles at the cost of not being able to fire for a short while they replenishes their rockets
 * Need more rockets: However the Cathlyn does have some weaknesses. The first being speed, due to the extra weight in rockets, their autocannons inability to deal with heavy vehicles or massive number, the fact that it takes a long time to reload their rockets, unlike the Estelle. And their rockets, although plentiful, usually aren't powerful enough to puncture heavier tank armour or structures
