• Royal Navy (RN) None in Sussex
• Royal Marines (RM) None in Sussex
• Royal Air Force (RAF) None in Sussex
• Army: 16 and 12 Royal Artillery Regiments, Thorney Island

With the exception of the two Artillery Regiments on Thorney Island there are no regular forces stationed within Sussex, however there will be a considerable number of individuals from Sussex who have joined the regular forces, who will return home on leave and may require access to NHS services. There will also be a number of individuals who will have settled their families in the county, but will still be serving in units outside of Sussex, who when returning home on leave may require access to NHS services.

The families of these individuals will come under the NHS for their medical needs, although the individuals' unit should look after both the individual and their family's welfare needs. However, those families living away from the unit home base tend to turn to the to local authority for assistance, and the unit will link them in appropriately. Not all will be living in private housing, so there will be a mix of social housing and some living with family.

It is harder to quantify the number of ex-service personnel in Sussex as there is no official monitoring of their placement once they have left the armed forces. This makes them a hard to reach community and is why organisations have to ask the question "have you served in the armed forces?" This will enable that organisation to ensure the individual and their family receive the appropriate support.
