I kind of see the group that Doctor Strange is a part of as planning, building, and creating an organization dedicated to protecting Earth from invasion. A lot of heroes are basically shown as superpowered police officers. Which is obviously a reactive job (outside of PSAs, community watch, and other such things). Militaries are more creative and active, and less reactive, so the heroes in military-like (or war-like) settings are more like the villians, only for good or order.
