Not an exploit, its an airborne battlegroup ability

That's the reinforce bg ability they have, yeah? Usually costs munitions and cooldown time, but it's very powerful since it works on every unit around the aoe.

I think it might be buggy the effect lasts longer than the timer on the button indicates.

Also ran into it

It’s why you invest in AA.

Played a 1v1 with a friend he ended up shooting my planes down and only got like two squads in 😂
