The overall aim of the Military Healthcare Ethics (MME) app is to support teaching in MHE that are used by military medical services across the world. This material will raise the level of understanding of MHE by military healthcare practitioners in order to maximise compliance with International Humanitarian Law and internationally agreed standards of ethical clinical practice. The material will also help practitioners prepare themselves for the moral and ethical challenges of conflict and disaster medicine and support their psychological resilience to the adverse mental health outcomes from this experience.
