Earlier this month, the U.S. Army announced it was establishing Detachment 201, a new initiative where four tech leaders, having been sworn in as Army Reserve lieutenant colonels, will work with the military to identify and solve problems. (The group is named after an HTTP code, 201, that means “request received, new resource created.”)

Among the recruits: Andrew (“Boz”) Bosworth (Meta’s Chief Technology Officer); Shyam Sankar (Palantir’s Chief Technology Officer); Kevin Weil (OpenAI’s Chief Product Officer); and Bob McGrew (A Thinking Machines Lab advisor and OpenAI’s former Chief Research Officer).

Their commissioning is somewhat of a milestone in Silicon Valley-military relations. Whereas a decade ago, most leading firms were shying away from or outright banning military projects, today their highest-ranking leaders are quite literally being sworn in as uniformed officers.
