How to prepare my sons for war
I have become increasingly worried about a large scale global war in the next 10-20 years, even if the odds are slim. I might be too old to be drafted, but I could easily see my 2 sons being drafted.
Obviously, as a father, I don't want to see my sons killed or maimed in war, so I'd like to start giving them skills and abilities to avoid physical conflict should a war arise. This is less "How do I teach them to fight" and more "What unique abilities would be so valuable that, in the event that they were drafted, it would make overwhelming sense to keep them off the frontlines?"
My first thought would be computer programming/coding and foreign language sufficiency (Mandarin or Russian seem like the most obvious choices), but what else? How could I help them have a natural proclivity for, say, logistics or media, etc.?
