Your logic is flawed anyway - "total effort" cannot be carried over from year to year.
That's largely very, very wrong. Shells you don't fire can be stockpiled. Tanks that aren't destroyed don't need replacing. And combat troops not killed, injured or mentally exhausted won't need replacing either.
Even better, if you're not straining to meet immediate combat needs you can build new production lines, tweak and replace key weapon designs.
