RE: Question on combat values and fire values
I always recommend new players play solo a few games - but with this twist. Play a few games in "HOTSEAT" mode with FOW on. This will give you a better feel for spotting, LOS/LOF, movement, ranged fire, etc. You play both sides, but if you are wanting to invest some time in learning the game, HOTSEAT is a great way to get a good feel for the mechanics of the engine above and beyond understanding the math of the rules.
Just my two-bits worth! Have fun!
