456820, if you think of something just after making your post, it's better to modify your existing post rather than make a new one. The modify button is in the top right hand corner of the post. It helps keep the thread clear and easy to follow. You're expecting each post to be by somebody different, so it is confusing it they're not. Thanks.
As for the original question, I have a vague recollection that there is an incoming missile eventHandler or something. Failing that you might be able to grab the missile with an nearestObject command, though since you'd need fired EHs on all the AT soldiers it could get messy.
