Abstract: Introduction: Military sexual trauma (MST) has been well documented, as has discrimination against members of the two-spirit, lesbian, gay, bisexual, transgender, queer, questioning, intersex, and asexual (2SLGBTQIA +) community. However, less attention has been paid to the addressing, resolving, and eliminating MST faced by 2SLGBTQIA + servicemembers. Methods: Between April and November 2024, we conducted a scoping review to map existing literature on 2SLGBTQIA + experiences of MST. We focused on two concepts: sexual orientation and gender identity as well as MST. After screening potential articles, we identified 28 eligible articles to include in our review, published between 2010 and 2024. Results: The 28 included articles contribute to our understanding of MST experiences among 2SLGBTQIA + servicemembers and veterans. We identified three dominant themes in the literature: the community faces increased risk and impact of MST; experiences of MST are coloured by gendered military norms, discrimination, and homophobia; and there is a need for culturally competent resources, supports, and services. Conclusion: The risk of MST is heightened for 2SLGBTQIA + servicemembers and veterans. This risk extends to negative health outcomes, yet less is known about other challenges. Important conclusions were made about how societal and systemic bias, prejudice, and stigma affect 2SLGBTQIA + servicemembers and veterans who experienced MST.Policy ImplicationsThis review found that there is a lack of supportive and culturally competent resources, supports, and services to address this issue. Approaching this problem from a social ecological lens provides opportunities for policy intervention on various levels.
