A Dominion-Breen fleet
The alliance formed in 2375 between the Dominion and the Breen Confederacy. The alliance transferred many Cardassian territories over to Breen control. As a result of this alliance, the Dominion were able to counterstrike against Federation forces in the Chin'toka system and return it to their control. The Breen and the Dominion were eventually forced to take action against not only the Federation Alliance, but the newly established Cardassian Liberation Front. Eventually, only Jem'Hadar and Breen vessels were left in defense of Cardassia Prime in the Final Battle of the Dominion War.
