Many nations are developing their military towards so-called Multi-Domain Operations with artificial intelligence (AI) as a pivotal component, despite identified challenges. Modern-day military operations underscore the need for updated battle management and cross-domain communication, central to the principles of Joint All-Domain Command and Control (JADC2). AI's potential is obvious, and while autonomous platforms revolutionize warfare, they introduce complexities in command and control (C2), which is also reflected in capability development. This study identifies suitable concepts for systemic analysis of military capability and is the starting point in forming a framework for C2 capability development in the context depicted. A number of concepts are identified; Combat Power, Fighting Power, Joint functions, Warfighting functions, Elements of combat power, Warfighting Capability, DOTMLPF(I), TEPIDOIL, Fundamental inputs to capability, Defence lines of Development, and Military Power. The study also highlights their systemic character and guides the reader briefly in matching issues with suitable concepts.
