Hey guys,

So at some point mid-april my friend and I are going to pick up and share Operation: Icestorm, now that I've finally worn him down to the point of defeat over the course of a year of "LOOK AT HOW COOL THESE MODELS ARE" and "IT'S PRACTICALLY A REAL-TIME WARGAME" repeated over and over between Warmachine games. He's getting PanO, I'm getting Nomads, and neither of us know how to play anything beyond the Quickstart rules after a few proxy games.
So, I guess these are my questions:

1. How do I into hacking?
2. How do TAGs operate differently from troops?
3. After Operation: Icestorm and the units it suggests (Iguana/Tunguska Interventors) what kind of thing should I be looking to pick up next?

Looking forward to actually knowing what I'm talking about next month!
