Your argument, if I read it right, is basically that I'm wrong and that the military is good at capitalizing on people's skills - and you give psyops as one example and also talk about people's credentials.
Sure, I don't disagree with you that in general, you can specialize in the reservists.
The point I'm making is that specifically for tech/software engineers/startup folks -- which was the genesis for the OP comment -- there isn't a great deal of skill overlap and capitalization. I'm not sure anything you've said disagrees with that.
