Development of military doctrine is perhaps the more important of all capability development activities because it determines how military forces were, and are used in conflicts, the concepts and methods used by the command to employ appropriately military skilled, armed and equipped personnel in achievement of the tangible goals and objectives of the war, campaign, battle, engagement, action or a duel. The line between strategy and tactics is not easily blurred, although deciding which is being discussed had sometimes been a matter of personal judgement by some commentators, and military historians. The use of forces at the level of organisation between strategic and tactical is called operational mobility.
• Military science
Because most of the concepts and methods used by the military, and many of its systems are not found in the commercial use, much of materiel is researched, designed, developed and offered for inclusion in arsenals by military science organisation within the overall structure of the military. Military scientists are therefore found to interact with all Arms and Services of the armed forces, and at all levels of the military hierarchy of command.
Although concerned with research into military psychology, and particularly combat stress and how it affect troop morale, often the bulk of military science activities is directed at the military intelligence technology, military communications and improving military capability through research, design, development and prototyping of weapons, military support equipment, and military technology in general that includes everything from global communication networks and aircraft carriers to paint and food.
