Irregular warfare (IW) is vital in today’s military planning. It’s complex and constantly changing, using methods that aren’t typical and adapting strategies as needed. Conventional warfare aims to fight and beat enemy forces. IW, however, works in messy political and social situations where standard rules of engagement don’t always fit. Because IW covers so many areas, the armed forces need to improve how they handle it. This means updating their policies, battle plans, teaching, and practice to meet IW’s demands. Policy needs to address new challenges like threat networks, information operations, terrorism, and cyber-attacks within a greater strategic framework.
