Combat Stress provides clinical treatment and support for ex-service members and veterans suffering from mental health issues related to their military service. It launched the Enemy Within Appeal to raise £30 million to increase awareness of psychological injuries in veterans and encourage earlier treatment seeking. The appeal integrated fundraising, marketing, and communications, including a pro bono TV advert, newspaper ads, and outreach by an appeal chairman and board. On launch, it saw increased donations, website traffic, and recruitment of major donors, tripling fundraising since 2005.
