It would be great, if with each encounter nation got increasing chance to learn stats of enemy weapons, which they are fighting. Losing the battle would result in lower gain of such knowledge and victory in higher gain. Intelligence efforts would of course also be included.
This way you would know (for example), that enemy started deploying new type of tank (or aircraft) against your forces and its stats. This would motivate you, to consider modifications of your weapons and production. Just like IRL, your country reacted to enemy tanks with thicker armor by upgrades to its own tank and antitank guns.
