In professional military education (PME), wargames and field-training exercises are among the pedagogical tools used to teach students to be professional officers. It is generally accepted that wargames are important sources of insight - even if, as Peter Perla (2012, p. 157) points out, they are "not real." Notwithstanding the truism that there exists a gap between the game and reality, the wargame is a tool designed to provide the learner something to aid them in the real world. There are discussions in the literature concerning which aspects of the experience and practice of gameplaying are relevant to the player's understanding of the aspect of reality their game is about; here, Perla's discussion of the categorization of wargaming analysis is useful (2012, pp. 231-239), as is the report Wargame Pathologies (Weuve et al., 2004). While, with a few exceptions, the literature on wargaming does not engage with the fundamental epistemological questions of wargaming, there is a tendency to demarcate the relevance of wargaming for professional competence to specific aspects or domains of knowledge. In this article I argue that wargaming and field-training exercises in PME shape the future officer's understanding and professional practices in much more profound ways than commonly assumed. Starting from Wittgenstein's philosophy of language and his discussions of what learning means and how meaning arises, I will show that, as far as learning to become an officer is concerned, wargames and exercises are intrinsically educative: learning inevitably takes place, and this learning shapes, in fundamental ways, how the officer understands and responds to situations they might face as a professional practitioner. The article proceeds in three steps. First, the theoretical basis for the argument, a Wittgensteinian view of learning and of professional knowledge, is presented; second, the nature of wargames and exercises, and their nature as sources for knowledge, are discussed; and in the final section, the implications for our understanding of wargames and exercises in professional military education of the preceding two sections are suggested.
