There are several ways to support the SF/USASOC troops via two organizations specifically founded that purpose.
1. Task Force Dagger Foundation at www.taskforcedagger.org
2. The Green Beret Foundation at www.greenberetfoundation.org
I am on the board of the Task Force Dagger Foundation and we stood up to help both the SF Soldiers in the various Groups, as well as the other USASOC units (e.g., PSYOPS, CA, Sustainement BDE, etc...)
The first step is putting one foot forward. There are lots of needs out there.
