The initial response to a catastrophe at a level pertaining to General Duties Medical Officers or similar forward-deployed tri-service personnel comprises acute care and triage skills, which are widely taught through prehospital courses and Foundation training. However, beyond that, the necessary workload becomes less clear. To provide comprehensive care in-theatre, there is the need to consider more nuanced and unfamiliar issues such as components in the immediate postcatastrophe landscape. These include aspects such as care of human remains, mental health, chronic conditions in the acute phase and the scope of military medical assistance within the wider relief effort.
