In June 2019, I found myself at NATO headquarters in Brussels, staring at a poster featuring a rainbow flag superimposed with silhouettes of armed forces personnel. It was an unexpected encounter. I was there along with my co-authors to launch our new book (Wright et al, 2019) and participate in the 43 rd Annual Conference of the NATO Committee on Gender Perspectives (NCGP). In the conference programme, what was billed as a 'side-event' discussing 'integrating LGBTQI perspectives in allied and partner armed forces' was scheduled for the upcoming Thursday. I was curious. NATO is dominated by cisgendered, heterosexual, militarised masculine norms (Ibid) and is an alliance made up of thirty member states with differing socio-cultural and military levels of LGBTQ rights. The inclusion of such an event, in such a space, felt a little radical. There were murmurings amongst the delegates.
