Major Cameron March MBE

Navy Command Pers Op OSM SO2

Cameron March joined the Royal Marines in 1963 and has served in many of the major conflicts that have involved the Corps in recent years. In 1996, whilst serving in the Headquarters Royal Marines as a MSF officer, he was asked to investigate and develop a suitable trauma management model for use by members of the Royal Marines. The resulting ‘Trauma Risk Management’ (TRiM) model has been used by the Royal Marines Command since 1998 and has been subsequently used by many other civilian and military organisations. In 2007 he was published in the book “Combat Stress Injury”. He was awarded the MBE in 2001 for his work in the field of Operational Stress Management. He holds an Advanced Diploma in the ‘Management of Psychological Trauma’ awarded by Nottingham Trent University

He recently retired as a Staff Officer at the Naval Command Headquarters where he was responsible for all aspects of operational trauma management and is now the director of the TRiM for Veterans Project and RMA welfare.
