Air-to-air missiles lock onto ground targets that you choose and download, but air-to-ground missiles such as Inferno and Claver do not lock onto those targets. Enter the xml editor and add function AirToAir phrase like this. Congratulations, inferno and claver are air-to-air and can lock and fire on your chosen ground targets, even warships and planes.

@JetElephant Ur too close u need to be at a distance to lock on

@DeezDucks Lol, well I got this from dev page... And I've played from when it came out. This is my third account.

@officialryanyang I've been playing this game for almost 5 years. I think I know how the missiles work.

@DeezDucks @JetElephant @jsaret @Nerdtronics @Lphoungphol @ImABoi Okay. For all of you, the real problem like the bridges, for example, or the convoy when you first start, grey boxes just tell you where the targets are. You need to either lock onto the real targets, or use unguided things like bombs for bridges. Also, don't spawn planes at final approaches. This will make them start the landing sequence, making it blue. Hope you figured it out.

I’m having the same problem in sandbox with Air to Air missiles. I mostly use ground units to fire Air to Air missiles, but they don’t fire, even when the target is selected, but they come up as blue. Help?

Computer or mobile mobile tap it computer click it

It seems silly that I get warnings when the enemy is locked onto me, but I don't get to know when I've got him.

@jsaret, thank you, didn't know you had to do that.

You must also select your target. If the box around it is grey, use the bracket keys [default] to chafe the target to the one you are attacking.

edit: *change

I think you gotta keep your recticle circle on the target for a quite some time. Even though it's a fire and forget it might take longer than the guided.
