Abstract

Since Russia's full-scale invasion of Ukraine in February 2022, French security policy has undergone a significant shift. Previously considered a reluctant NATO ally, France has now assumed a central role in the collective defence of Allied territory. One of the most prominent examples is its role as framework nation for NATO's Forward Land Forces (FLF) in Romania. This report analyses the design of FLF Romania through the lens of several categories: type of presence, contributing countries, type of units, command and control, military mobility, and framework nation-host nation relations. Strengths and challenges are identified in relation to these categories. Regarding the type of presence, the study reveals that France has opted for a flexible approach characterised by a rotational multinational battle group in Romania and additional units in readiness at home. France values interoperability over multinationality, contributing to a cohesive FLF with relatively few participating countries. In the event of reinforcement, FLF Romania would likely consist of a mechanised brigade with units from France, Belgium, Luxembourg, and Spain, reporting to NATO's Multinational Division Southeast. While France's experience in leading military operations abroad has been an asset, challenges include military mobility and the polarised political environment in Romania.
