The announcement was made by David Cameron at the first Armed Forces Charities reception in No 10.
Since Chancellor George Osborne announced in October 2012 that £35m of funds from fines imposed on the banking industry would be used to benefit the armed forces community, £13.5m has been awarded to military charities.
Last night, by announcing a further £9.2m, the Prime Minister has taken the funds to be shared between 72 charities to £22.7m, including £2.7m for the Help for Heroes Hidden Wounds Programme.
In Aberdeenshire, Horseback UK is receiving £110,000 funding for an arena, which it uses to rehabilitate veterans through equine therapy.
In Glasgow, the Coming Home Centre will get £107,000 to develop four resource centres for members of the armed forces, those in transition, veterans and their families.
Three councils - East Renfrewshire, Renfrewshire and Inverclyde - will receive a total of £87,000 to help establish a standard, veterans and service leavers' community pathway hub, which will provide a one-stop shop for housing, employment, benefits, addiction and medical treatment.
Gardening Leave, an Ayrshire-based charity, will receive £73,000 to convert a vacant bowls pitch and pavilion near Dundee to provide horticultural therapy for troubled veterans.
Royal British Legion Scotland will receive £14,000 to aid their work in Inverness providing care for ex-service personnel in care homes in later life and to expand their operation for care in partnership with Erskine.
