Allying militarily and entering combat jointly with other sovereign powers is hardly unusual. Such practices extend the length of human history. The first notable altercations, wherein distinctive communities, whose interests did not necessarily align in full and whose power dynamics may have been skewed, entered into a coalition with the purpose of utilising their joint military capabilities towards a shared end can be traced back to ancient Greece. With the growing interconnectedness of this epoch, such practices, rather than having faded in relevance, have instead become a central component of national and international security structures. Indeed, matters of a transnational security nature have progressed, evolving into a concern of multilateral proportions since the Second World War. There is no doubt that the growth of multinational military operations (MMO) is partly due to the fact that they offer a plethora of advantages, from the possibility of increased efficiency and decreased mission expenditures to the supplementary legitimacy such practices may offer.
