The Tal Shava (Imperial Marines) were a Romulan Ground Forces elite unit, the largest of the three elite units fielded by the RGF. They were experts at getting onto and conquering enemy occupied planets. During the Dominion War they played key roles in the Liberation of Benzar and during the Kalandra Campaign.
