The author goes out of his way (and I think it was a good call), not to call out "army things" that make for good co-founders, but to frame it as "these are qualities of good choices that were made obvious to me in an army context". Specifically:
* Trustworthy
* Professional
* Competency
What other (non-business) contexts could we frame this type of article as? I suspect team-sports will stick out as an example, but where else?
