Okay, so I'm coming up with a complete blank on this one. I've looked all through TacOps so I don't think I could have missed it. (Maybe in errata though?)
Anyway, was talking to someone and they said you could set your AMS to engage any missiles that went through its arc. (Therefore could protect lance mates.)
(Also said could do the same thing with Aero units, but I haven't looked through StratOps.)
Is this an actual rule, or only home-brew?
