The Romulan ranking system was a hierarchical collective command structure used within the Romulan Star Empire, seemingly descended from the ancient Vulcan ranking system which was also used by the Vulcan military forces until the mid-22nd century. Both the Tal Shiar and Romulan military had shared but separate ranking system, and their rank insignia shared many of the same physical elements, and appeared in the colors of silver, bronze, and gold.
In 2266, after the commander of the Praetor's flagship learned that one of his officers, Decius, had transmitted a coded message back to Romulus, the commander informed his officer that he was "reduced two steps in rank" on account of "your carelessness might have ended this glorious mission." Following the interaction, the commander's centurion advisor warned that Decius "has friends, and friends of his kind mean power. And power is danger." (TOS: "Balance of Terror")

Background information
Terminology
The ranks of centurion and uhlan are ancient Earth ranks (Roman and Polish respectively) not known to be used by any other Star Trek cultures.
Given the rank of sublieutenant, there is presumably a lieutenant rank at some point in the Romulan military history. No Romulan has been referred to as a "Lieutenant" in Star Trek.
In Star Trek, Ayel refers to Nero as "Prod Nero." In a deleted scene in which the Narada is surround by Klingon warbirds, the subtitles created by the filmmakers for the Romulan dialogue translate Prod as "commander." However, according to a DVD audio commentary for the film, "Prod" was intended to mean "Praetor."
Insignia
Modern Romulan rank insignia were not introduced until the TNG Season 6 episode "Face of the Enemy" – establishing insignia for commander, sub-commander, and major. The same episode took further strides, both in dialogue and script notes, in establishing distinctions in Romulan uniforms, ranks, and protocol. Of note, the differences between the Tal Shiar and military uniforms, and, in the case of DeSeve, it states that "[h]e wears the unadorned uniform of an enlisted Romulan soldier."
Rank insignia only appeared sporadically thereafter, and in subsequent episodes featuring Romulan officers that season, including "The Chase" and "Timescape", no officers or crewmen wore insignia. The two Romulan commanders appearing in TNG Season 7 episodes "The Pegasus" and "All Good Things..." did, however, notably wear the same insignia that had been established the previous season.
The DS9 Season 3 openers, "The Search, Part I" and "The Search, Part II", established a new sub-commander insignia, and while all of the officers who appeared in "Visionary" wore no insignia, "The Die is Cast" introduced the insignia for colonel.
The VOY Season 4 episode "Message in a Bottle" showed a slightly different commander insignia than was previously established in TNG Seasons 6 and 7.

DS9 Season 7 introduced a new, unspecified Tal Shiar rank insignia worn in "Inter Arma Enim Silent Leges" – consisting of a new burr pin with two crescent pins worn in the reverse position – and was worn by the Chairman of the Tal Shiar.
Finally, both "When It Rains..." and "The Dogs of War" featured the insignia for a general, which actually had one less crescent than a commander wore. Of note, General Velal was previously referenced as a sub-commander, which would explain the seemingly lower representation in rank insignia, but also matched neither of the previously established sub-commander insignias.
