Anyway, the point of all this is that I have been fiddling around with a very simple toy-soldier game design for modern combat, platoon and below. For ultramodern western infantry versus irregulars, I was wondering if a simple reduction in the movement rate but a saving roll for the armour would be a workable trade off, and more importantly, encourage both sides to fight the way they actually do. The western troops would get more-and-more special abilities for having the extra armour (a saving throw), radios (a less random activation system), ammo (better hit and/or suppression chance) and ECM (obvious), but at a cost to movement rate.
Similarly, western troops in WW2 carrying too much stuff would be punished by a slower movement rate.
Then, to be really controversial, the same penalty would apply to a simple morale test when attacking.
