I would like to know what term of service the authors have in mind. I didn’t see it in the article. The last time I remember a politician suggesting a draft was a few years ago. A democrat by the way. I don’t remember who it was. I think he wanted two years. I think this would be a total waste. Even a basic infantryman in the modern US military needs far more technical knowledge and training than required in WW2, Korea, or Vietnam. A two year draft would have most soldiers leaving shortly after they were actually qualified. It would have to be at least four years or, if in actual wartime, you’re in until the end.
The Army has had 2 year enlistments for at least more than a half century and still has them.
