I think they mean doctrine as in military doctrine (https://en.wikipedia.org/wiki/Military_doctrine), which is a somewhat different idea than, say, religious doctrine. Religious doctrine can easily get rigid and legalistic, and compliance with it can become an end unto itself. Military doctrine is something a military would use in order to make the organization effective at a certain kind of task or endeavor.
