Adarak Prime
From Star Trek : Freedom's Wiki
Adarak Prime is a planet located in the Cardassian Union. During the Cardassian - Federation War it was the location of a weapons depot, which was defended by a single Cardassian garrison.
In 2375, Odo identified a weakness in the depot's perimeter defenses which could be exploited by a small team. The mission was undertaken by the Cardassian Liberation Front. (DS9: "When It Rains...")
