These sources provide an overview and critical analysis of Multi-Domain Operations (MDO), a concept aimed at integrating military and non-military activities across all domains to achieve synchronized operational effects. Several articles from NATO and military think tanks explain MDO as a crucial evolution for modern warfare, emphasizing the need for faster decision-making, advanced technology like AI, and coordination among diverse actors to counter adversaries who attack simultaneously across multiple fronts. However, a critical investigative piece and other analyses highlight significant challenges, including vague definitions, lack of clear implementation plans, technological immaturity, high costs, and the inherent difficulties of achieving seamless coordination among numerous nations and military branches, often questioning whether MDO is a practical solution or merely complex theoretical jargon.
