Currently, your manpower pool is just that, a pool, using it for soldiers does not have any negative effects, while in the real world, those men are being drafted into the armed forces from civilian jobs. (unless they are completely unemployed)
I suggest that manpower be upgraded so that the more you put into the armed forces the tradeoff is it impacts your production amounts. This would reflect the hit your economy takes for having fewer available workers.
