AssessmentModerate confidence

Figures carry their own uncertainty. Population, economic and military-spending data in wartime are estimates, often contested; every figure below shows its as-of date and a confidence grade, and leadership positions reflect the last review date and change without notice.

What this actor is

Bulgaria hosts the Italian-led Forward Land Forces battlegroup. Bulgaria publishes no armed-forces structure in English, so Vigil holds almost no Bulgarian force structure.

What this record does not yet carry

No posture block is authored at P1. Objectives, constraints and red lines are claims that need a defence strategy or an official statement behind each line, and the verification sprint did not establish that source base for individual allies — it established what states publish about their FORCE STRUCTURE, which is a different question. Posture is authored when the documents behind it have been read, not to make the actor set look uniform.
