I still need to get the hang of manual targeting, but other than that I have just about everything else down pat (although I still haven't unchecked the Weps Officer help). I was never good at math (yet I was championship shooter, so go figure) but now is a good a time as any to start using some of my brains while I'm playing.
And yes it was a real rifle, torpedoes have extreme difficulties making it 500 meters downrange through the dirt.
