In our run through it was a small scenario- a Russian Tank had broken down at a petrol station (well I had to give the petrol station a run out evenually.) and the crew had to defend it until reinforcements made it to the village and they called in the mechanics. Meanwhile the local insurgents move in for the kill.
The troops quality impacts both the troops firing ability, effective range and defence capability nice and simple and very easy to remember. Fire fights are resolved with an attack roll and a defence roll with attackers hitting on a 4,5 or 6 and deenders a 5 or 6. You add defence dice for cover which is pretty good against Small Arms, but my tank crew faired less well when an RPG round hit them, whilst defending the petrol station.
