Kazon shuttle

A Kazon shuttle was a type of auxiliary craft utilized by the Kazon during the 2370s. These vessels were smaller in size than a Kazon raider, and could be manned by a crew of as many as three.
With the assistance of Seska, Maje Culluh of the Kazon-Nistrim had the of a Kazon shuttle specially modified for use in what was later a successful raid on in 2372. 
The Kazon then lured Voyager to an ionized hydrogen cloud with an automated message beacon that transmitted a Starfleet frequency. When Voyager attempted to tractor in the beacon, they were attacked by Culluh's raider. The raider focused its attack onto on section of Voyagers shields, which created a hole that the shuttle, which had been hiding in the hydrogen cloud, passed through so as to puncture a hole in Voyagers hull. 
Once aboard, the three Kazon aboard proceeded to the transporter room, where they were able to successfully steal a transporter module and return to their mother ship. 
As a result of the attack, the Kazon shuttle remained lodged partway into Voyagers hull, making it impossible to the ship to create a stable warp field. Removal of the shuttle was accomplished by rerouting additional power to the containment field, and then towing the lodged shuttle out with one of Voyagers shuttles. 
Neelix, who had several dealings with the Kazon during the years prior to that incident stated that he had "never seen the Kazon do anything like this before." Tuvok explained the situation, stating "until now, the Kazon have never had an adviser with Cardassian, Maquis, and Starfleet tactical experience." ()
