Police Rank Progression titles...

What follows is a rather superficial list of police ranks (and superficial is fine for my purposes) taken from Wikipedia. What would you suggest for a per rank progression of these titles? Do you think it would be as simple a 1 to 1 progression matched to this list? Or do you think some of these would group into a single level of the Rank advantage?

Thanks in advance!

Note: I'm not really concerned with the accuracy of this list with real-world police agencies. What's presented is more or less adequate.

The United States of America police rank model is generally quasi-military in structure. Although the large and varied number of federal, state, and local police departments and sheriff's office have different ranks, a general model, from highest to lowest rank, would be: Sheriff (the highest ranking law enforcement official within a county) Chief of Police, Police Commissioner, Superintendent, Constable (highest ranking law enforcement official within a city/municipality) Chief of Police, Deputy Commissioner, First Deputy Superintendent, Undersheriff Deputy Chief, Assistant Commissioner, Deputy Superintendent, Assistant Sheriff Assistant Chief, Assistant Superintendent, Associate Sheriff Commander, Deputy Assistant Superintendent, Chief Deputy Sheriff Colonel Lieutenant Colonel Major Captain Lieutenant Sergeant Major Master Sergeant, First Sergeant Sergeant First Class, Sergeant II Sergeant, Sergeant I Master Trooper, Master Trooper Detective, Investigator, Inspector (this is generally only an actual rank in larger departments, and often include different levels for "career detectives") Corporal Grade 1, Senior Trooper Police Corporal, Deputy First Class, Trooper First Class, Master Patrol Officer Police Officer, Deputy Sheriff, Trooper, Patrol Officer
