Training script question

[Sniper]

Hi everyone, I tried searching but I wasn’t able to find what I needed.
Is it possible using the IF line to display a message if a certain object (both moving and static) is destroyed or a moving object reaches a location (for example it reaches a certain city or steerpoint or crosses STP lines and threat circles)?
I’m asking this because I’d like to try writing a script that displays realistic radio comms (I’ll start with just text and maybe later sounds) for example if the package’s target is destroyed or a bandit crosses a STP line that defines the DMZ or if any other specific conditions are met within the TE…
