Hello, I'm extremely new to the game I'm playing solo, I've just raided an airfield and got myself a AH-99 (stub wings) from the arms dealer. however I cannot figure out how to use the guided missiles, there's no laser icon when I turn it on in the camera pod with the laser in selected weapon and when I fire a scalpel or ASRAAM they don't lock on or impact they just disappear into the ground, I've tried ctrl + T to area lock but nothing, are they vehicle lock on only? Trying to take down radio towers from afar which also doesn't seem possible because I've dumped 400 HE rounds into them and they do nothing to them. Also is there a way to change the HUD colour, reticles blend Into the clouds, thank you for any help
