The Rocket Artillery Squad is a siege infantry unit that fires devastating volleys of rockets into enemy formations, which are capable of damage all but the hardiest of fortifications. It isn't as accurate as a Howitzer but accuracy is not important — it has a larger spread of fire, thus having a greater field of impact. Unlike most other artillery units, the Rocket Artillery Squad is not built from the Arsenal, but is instead recruited from the Academy or Nobles' Court.
When used in large numbers, these units can easily devastate most armies and light fleets. Compared to the Howitzer, the Rocket Artillery Squad is more specialised, and deals added damage to heavy and medium ships as well as the enemy's production structures, but performs poorly against fortifications and infantry.
