Thought about that recently in terms of infrastructure.

Are the weapons manufacturing? Or our communication infrastructure perhaps? Is it a valid target, hard to answer, but they were in the last big state v state war. I would imagine it would depend on the type of war we are in I suppose.

It ends up very messy. We as defence personnel signed up to defend our country, they did not and I would think, more likely to walk away from the job leaving us with less usable equipment and drastically lessening our ability to project force.

Of course we likely can't man every factory with defence pers, but we can at least train our people to do the jobs we used to be allowed to do, like service our equipment. Especially since some of those are ex-defence personnel anyway.
