The small Lithuanian town of Rukla, more forest than prefabricated buildings, is an important site for Germany in its security architecture. Here, the Bundeswehr leads a multinational NATO battlegroup on the alliance‘s eastern flank. In 2018, I went there because I was interested in the strong sense of threat that Lithuanians felt towards Russia. What is the purpose of regularly rehearsing a war with heavy weapons in Rukla? In times of cyber and information wars, this seemed to me like an outdated backdrop of deterrence. At the time, I could not imagine that this heavy equipment would become important again so soon. My film turns back the time seven months before Russia‘s attack on Ukraine. It shows military routines and a place that was already full of military secrets in Soviet times.
