i don’t think we generally deploy our actual good hackers abroad (i’m also not sure how many of them are directly employed by the govt vs contractors)
However, I would be skeptical that the people in uniform are the "actual good hackers." Unfortunately, uniformed career paths (set by law, in many cases, and certainly long tradition) are not conducive to anyone developing any deep, technical expertise. I think we have cyber operators in uniform largely to do the things that legally can't be done by someone who's not in uniform. I think they are backed by a lot of civil servants and contractors (including academics on loan or moonlighting) with the deeper expertise. I think this is true for a lot of the more technical military systems, by the way, not just a cyber thing, e.g. aviation, air defense, nuclear stuff.
