Thank you for your interest in contributing to SADA. We have set up several different donation tiers, each of which includes a variety of benefits. Money contributed to SADA will help protect and promote military installations, prevent closures in the future, and will send a strong message to local and national government leaders about the importance of our military facilities to this region. Enlist in the SADA Corps. We appreciate your generosity. Please make checks out to Southern Arizona Defense Alliance.
