Predavolk, it's very simple. I see a contact, I use the marker and rulere to scribble a bit, I charge in... nothing. I dive, listen, wait. Nothing. Simple as that, I really don't know how to explain it better.
Part of the equation may be that fact that I suck at geography (got really bad grades from that, plus, I could probably get lost in my own closet) and maths (I'm
very bad at this) so I'm flabbergasted by all the angles between different points and bearings between the angles of heading of these points, being on the move as they are. Sometimes angling their bearings out. Or in.
Southwise. With differing speeds. Er. No?
Oh, and you should've seen my facial expression when I read about manual targeting...
