The theory of normative practices has proven to be helpful in eliciting the normative dimension of social practices. In this article we apply the theory to military practice. Since current military missions are Network Enabled Operations, which mandate a strong focus on cooperation with other military and non-military partners, an additional framework is needed to understand actual problems in such missions. We have extended the theory of normative practices with interrelations (enkaptic, part-whole, and juxtapositional). Two cases from missions in Afghanistan have been analyzed to show the usefulness of the theory of normative practices and its extension with interrelations.
