Yeah...the game's essentially based around some dice and a ruler. Each unit has a certain ballistic skill, wounds, armour rating etc etc. Turns are taken in three phases: movement, shooting and assault, if I remember correctly. Each unit can move certain distances and shoot certain distances based upon their stats. Various units also have special abilities and attacks.

It all gets fairly complicated, although it's not too hard to learn the basics.

I'll post pics if I can actually find my army.
