Yeah, 4,000 out of a cohort of 13,000 means you can be very selective. Easy enough to get rid of the real fuckups and the hell-no-way refuseniks. Give the rest some real choice in what they'll be trained for, and you might only have to say no to those with a clear mismatch between their hopes and what they are fit for.

It's interesting that they are choosing to draft both men and women. Not a lot of places draft women.

That's out of ~100,000 kids per year.

Oh. So they can probably just take volunteers, then. And they don't even need to take all of them.

Volunteers provided 95% of the recruiting target. Conscription is to fill the rest.
