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.

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.

CCF’s may include Royal Navy, Royal Marine, Army and Royal Air Force sections.

Sea Cadets and Royal Marine Cadets
Whether at sea or on land, the Sea Cadets offers young people across the UK amazing opportunities for personal development - by learning new skills and working in teams - they offer an environment where young people find new confidence and inspiration.
Established in 1856 the Sea Cadets was created by communities wanting to give young people instruction on a naval theme. Traditionally old seafarers provided training while local businessmen funded the unit building.

Sussex Army Cadet Force has 27 detachments covering the whole of East and West Sussex as well as Brighton and Hove. Divided into 4 Companies they also have a Corps of Drums, Signals and Kitkar teams. Their Headquarters is at Highcroft House, in Brighton - an old building, built within the grounds of the Army Reserve Centre on Dyke Road, and it is home to our Head Quarters staff team.

Sussex Wing Air Training Corps

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.
