Glinn Bezerok Hatel was the first officer of the Cardassian warship Ghiletz, serving under the irascible Gul Surtak Speros as of 2375. In that year, Gul Speros was one of those who rebelled against Dominion control and helped to found the combined Cardassian-Starfleet rebel force, the Thirteenth Order. (Star Trek: Sigils and Unions--The Thirteenth Order)
When the Thirteenth Order commandeered a Galor-class warship, soon "christened" the Zerayd, Gul Speros pushed for Hatel to be installed as the ship's first acting commander. Hatel would continue to be referred to as a glinn and be treated according to that place in the hierarchy, but was vested with all other powers typical of a ship's commander.
