Army researchers find the best cyber teams are antisocial cyber teams

I'd argue that these are likely very highly socialised teams.

They know one another, they trustbone another, they know their roles, and they communicate most effectively through their technical tools and interfaces.

That's supported by the paper (submission draft in Sci-Hub):

[F]ace-to-face interactions detract from and perhaps distract cyber defenders from the focal task of maintaining all ten services and successfully defending the integrity of their network.

Talking isn't bad, per se. It's generally less efficient and tends to indicate problems rather than smooth functioning.
