How are opportunities to critically reflect upon military violence and militarization shaped by museal representations of a country's military history? Inspired by a critical heritage perspective and feminist international relations research, this article contributes to the scholarly discussion of the political implications of military memory making. The aim is to analyse how military violence is framed in official heritagization of the Cold War period in Sweden. Based on fieldwork at three military museums, the article discusses how framings of violence affect opportunities to politically and ethically engage with military issues and the use of force. A central question concerns how gender underpins representations of violence at the museums and how this gendering affects politicization. The analysis discloses that military violence is framed as sacred sacrifice, as ‘pure’ technology, as play and as (male) omnipotence. The argument made is that such gendered frames obscure and depoliticize problematic aspects of military violence.
