Nations, forces, and people develop different command styles for many reasons – and there seems to be little that links so many different styles. It is built as much on experience, strategic culture, and the company you keep as it is developed from formal education (although that clearly plays a part).
Both Sir Lawrence Freedman and pub landlord Al Murray have released books about it recently, and they have their merits. Neither author addresses C2, however. But compared to a shared understanding of what command is, understanding the control element is almost impossible. Too many definitions bear little resemblance to the lived reality of those in the profession of arms.
