BTW is IR jammer really works? Haven't noticed it to be honest.
Yes, You can deactivate the missiles by using it.
Oh so it's not automatic? I wanted to ask how do I use it then but discovered already - landing gear button. I would add this tip both to control screen and weapons description screen.
It's mentioned in the Tutorial when you selected Sawfly Warrior.
Ah I see then. Didn't try to complete it with that helicopter.
