Odo points out Adarak Prime
Adarak Prime was the inhabited prime planet in the Adarak system. This Cardassian planet was located in the Alpha Quadrant.
In 2375, during the Dominion War, Adarak Prime was the location for a weapons depot, which was defended by a single Cardassian garrison. This depot was considered by Odo and Garak as a vulnerable facility that the Cardassian Liberation Front could target for attack. They identified a weakness in the depot's perimeter defenses which could be exploited by a small team. Garak would disable the depot's security protocols. (DS9: "When It Rains...")
While Damar was receptive to the plan, it is unknown if ultimatly the decision was made to attack the base.
