If a war broke out - say the US defending Taiwan against a Chinese invasion, or any other likely scenario - would there be any realistic use for enlisting draftees from the general US population?
All the current naval ships and aircraft can be manned from current full-time soldiers, and it would take years to build more. So that basically leaves deploying them in army units or as marines.
But even so, I imagine it would take a least six months to mobilize, train, and equip untrained civilian draftees. You'd have to imagine the US and China would have battered each other into the ground by that point. The US certainly wouldn't be stupid enough to try to invade the Chinese Mainland.
So what purpose would drafted civilians even have?
