Defence nurses form the largest registered specialty in the UK defence medical services. Once qualified, defence nurses maintain and develop their nursing and clinical skills in appropriate healthcare settings, and can be deployed in operational environments such as Afghanistan. Workforce planning and staffing establishment levels are defined to meet the needs of British armed forces, allies and, potentially, local populations. Since the workforce is geographically dispersed, deployed or undertaking non-clinical duties, there are constraints on nurses’ attempts to maintain basic skills and access continuing professional development. This article explores the concept and the developing role of defence nurse lecturers in improving educational support for defence nurses.
