Enlisted Ratings
Version 2.0

Ratings (Occupational Specialties)

What follows is a sampling (not necessarily comprehensive) of the enlisted ratings (occupational specialties) which would be found aboard most ships, stations, and starbases in ASR Star Fleet.

Enlisted personnel, as the rank structure acknowledges, have pay grades and ratings (occupational specialties). The use of the following system is optional (subject to the approval of the fleet administration and commanding officer of the unit), but proves the opportunity to flesh out the ship's crew. A couple specific notes about usage follow.

First, in ASR, for simplicity sake, ratings are earned when the person makes the title/pay grade of Petty Officer Third Class (E-4). In the real world, some ratings may be earned earlier (strikers). However we avoid that in ASR, save for yeomen. Rates identify personnel by rating (occupation) and pay grade, and are denoted as follows: a petty officer third class who is a legalman would be LN3. A chief petty officer who is a master-at-arms would be a MAC.

For example:

  • Pay Rate (Title and Abbreviation)= Rating Title or Rating Abbreviation

  • Pay Rate E-4 (Petty Officer, 3rd Class or PO3)= Master-at-Arms, 3rd Class or MA3.
  • Pay Rate E-5 (Petty Officer, 2nd Class or PO2)= Master-at-Arms, 2nd Class or MA2.
  • Pay Rate E-6 (Petty Officer, 1st Class or PO1)= Master-at-Arms, 1st Class or MA1.
  • Pay Rate E-7 (Chief Petty Officer or CPO)= Chief Master-at-Arms or MAC.
  • Pay Rate E-8 (Senior Chief Petty Officer or SCPO)= Senior Chief Master-at-Arms or MACS.
  • Pay Rate E-9 (Master Chief Petty Officer or MCPO)= Master Chief Master-at-Arms or MACM.

There are two types of mustang officers (those who came up through the enlisted ranks) that do not go through OCS or DCO progams: Warrant Officers and Limited Duty Officers. Enlisted personnel who later become warrant officers or limited duty officers almost always serve in same area in which they obtained their enlisted rating. Limited Duty Officers have a rank ceiling of O-6 (CAPT), and ARE eligible for command, provided they have the appropriate designator (training and qualifications).

Like all such optional material, it is understood that many ships may choose to adopt all, part, or some of the system, or not use it all. That is fine, and local variation is expected. However, for those who do wish to use it, this should provide a guide to the often ignored world of enlisted personnel.
