Rapid fire anti air rockets clear the skies.
Offense: This has a lot of firepower when fully leveled and with a fire rate of 4 rounds per second there isn't anything out there that shoots quicker. It is very deadly to aircraft and lightly armored vehicles or infantry. It has practically no armor and very little health so it must be deployed carefully so as to not be out in front otherwise it is toast. These have a relatively high speed so keeping them in the rear is difficult unless you use a lot of recon or faster tanks. They are also murder to all the infantry squads so if the enemy is murdering you with those Liang's Reapers, Rocket squads, Ranger Squads or Exterminator squads this will kill all three before they even have a chance to shoot back.
Defense: These are deadly to aircraft so long as they can get a shot off but with only a range of 23 there are helicopters with longer range that can kill it. Any tank or tank killer unit can handle these with ease. This unit is actually a tank unlike all the other air denfense units so Hastatus Snipers and Prime's can kill them effectively though if this gets in range to fire the Hastatus infantry is probably going to die as well. Best to send a tank after it.
This is the long range variant of the Raiynin's Defense though it is also the cheapest variant but not by much.
