In recent decades, military organizations have deployed much more extensively in nonconventional operations. Army units are deployed as peacekeepers, navy vessels engage with migration control and search and rescue (SAR) operations and the air force delivers humanitarian aid. Do recent trends imply that the military is switching to new kinds of core tasks, including but not limited to what Janowitz referred to as ancillary tasks? This chapter argues that even though the kinds of tasks have multiplied, it is very slow and inertial to shift from a focus on combat core tasks to multiple tasks. In other words, the military is torn between its classical skills-which form the core of military cultures-and the requirements of ambidexterity.
