Cardassian Militia 41

From Memory Alpha, the free Star Trek reference

Cardassian Militia 41 was a Cardassian military unit in the 2360s. Gul Dolak was a part of this unit. (TNG: "Ensign Ro")

Gul Dolak's statement that he represented the Cardassian Militia 41 (which was distinctly pronounced as four-one) may mean that he was in the Fourth Order, First Battalion.
