AbstractIn the autumn of 2017, two Category 5 hurricanes caused extensive damage in the Caribbean. This resulted in the activation of two Role 2 Afloat (R2A) teams in support of Operation RUMAN, the military response to provide Humanitarian Aid and Disaster Relief (HADR) to the affected area. This paper documents the deployment of the R2A capability during Op RUMAN and outlines the main lessons identified in the delivery of HADR in the maritime environment.
