Although states differ in their approach, with some beginning to prioritise non-military action to tackle systemic drivers of insecurity, various forms of coercive power predominate, particularly Military Capabilities. The scope of these capabilities has developed. Traditionally, military capabilities were mainly land- or sea-based, and in smaller countries, they still are. Elsewhere, the domains of potential warfare now include the air, space, cyberspace, and psychological operations. Military capabilities designed for these domains may be used for national security, or equally for offensive purposes, for example to conquer and annex territory and resources.
