SSAFA Forces Help, the charity for the armed forces, has developed a corporate friends scheme to boost regular donations from the UK's major arms and defence manufacturers.
The companies involved include Babcock, BAE Systems, Lex Defence, KBR, and the industry's umbrella organisation, the Defence Manufacturers Association.
The latest manufacturer to join is Amec.
The scheme "allows the industry to give something back to those who have made a contribution through the services", said minister for defence procurement Lord Bach. The charity's beneficiaries are serving and ex-service members and their families.
The charity continues to rely on the fundraising activities of its 100 local groups. In addition to corporate support, its income comes from legacies, trusts and individual giving.
SSAFA Forces Help estimates it helps around 75,000 people every year via its network of 7,000 volunteers.
