This paper will discuss the Resistance Operating Concept and how nations should prepare to resist a potential enemy before an invasion takes place. Oriented towards the self-defense of small countries by a resistance or partisan force, it describes past examples of resistance groups in Europe. Specifically, by discussing the long-term survival of resilient organizations, its focus will be on the basic factors crucial for an underground resistance, including security, organization, and training. It also considers the need for a practitioner-oriented manual that can be disseminated at the widest levels to guide and enable future resistance operations.
Russia’s aggressive actions in the vicinity of the borders of the Baltic states have stirred the discussion on the Comprehensive defense concept. This concept is based on whole-of-government and whole-of-society involvement in resistance against occupying power. This article examines the role of the armed forces in the resistance movement from a small state perspective. To define the role of the armed forces, this article scrutinizes the historical experience of the Latvian Forest Brothers and the traditional development phases of the resistance movement. The article argues that the armed forces must form the backbone of the armed resistance, which integrates the other security forces and the civilian population into the national level resistance movement.
