The Progressive Justice is a new Air unit in league of war
Offense: This is another Rail gun helicopter. It is deadly to infantry being able to kill most in one shot and it is also good against tanks. They are very fast as well and seem to have about the same speed as the Twa Corbies. They are very vulnerable to AA units like most helicopters and also recon units that can shoot air targets. But the instant they group together, unlike any other unit, all of them fire at the same time, hammering enemy units. So tough tanks like the mighty ★Janissary III★ and the nasty Janus go down in an instant. At level 50, even the toughest units will soon be terminated with ease. The Progressive Justice can't target other helicopters, however, so screen with an AA. Overall, just as annoying as trying to swat down a fly.
Defense: If these miserable flies group up, you will LOSE. Long range AA can kill them before they become a threat. They are very quick and can maneuver in and out of range for short range AA units so be sure to deploy lots of them if that's all you have! These helicopters cannot target other air units, so those work, too--just be sure those rockets are fast shooters or can one-shot these units.
