  • 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, 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 local authority for assistance, and the unit will link them in appropriately.

The majority of the Association comprises volunteers, presided over by the Lord-Lieutenant of each County, ranging from high-ranking serving and retired military Officers, through local Councillors to enthusiastic locals, with no military experience, but with a will to support the Armed Forces and Cadets; so it can be seen that the Association has close links with the Community because it is part of that Community.

  • Managing the volunteer estate (Reserve, Cadet and Training Centres). through building new Centres, maintaining current Centres to the required legal standard and ensuring that all sites are kept in good condition, fit for purpose and secure.

It is harder to quantify the number of ex-service personnel across Sussex and Kent & Medway 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 British Armed Forces?" This will enable that organisation to ensure the individual and their family receive the appropriate support.
