As Don says the random factors are what make the game as you have to adjust your strategy to compensate for the surprises. It all evens out in the end but produces some tense moments or lucky openings.

Fortunately the game guide gives clear info on what units are capable of, the different systems (range finder etc), effects of movement, suppression etc.
Along with the likely effect the weapon will have on the target.

After a while you get a feel of what your & the enemies forces are capable of so you can predict the likely outcome of an exchange & play to your units strengths & weaknesses.
Most of the time things go pretty much as expected & its the ones that don't that make it interesting.
The game catches the fact that while you can predict the outcome there is no certainty in war.

My best moment from the last battle was an ATGM team that I thought was lost doing a full rally gaining its movement points & shots back & taking out the tank that fired at it. Next turn I was able to capitalise on this surprise outcome.
