Apologies, but this is dry as a bone! Doesn't help that I've thrown on an automated voice. But hey ho! it's only 4 and a half minutes long.
I should add that you can only target a model if it is visible for your operative. ie. a straight, unbroken line can be drawn from the head of your operative to some part of the enemy model (even the tip of it's rifle)
