Snosk

The Snosk was a Breen Confederacy destroyer that was in service in the 2400s. 

History
The Snosk was part of a Breen task force that attacked a Deferi patrol in the Orellius sector block in 2409. It was destroyed by Deferi-allied forces. 

Background
The Snosk's name appears to be part of a running joke in Star Trek Online. "Snosk" is a word for snowshoes, and given the Breen association with cold all the missions in the "Breen Invasion" story arc (of which "Aiding the Deferi" is a sidequest) have titles punning the word "cold".
