Thats usally how it is on most radio systems as far as issuance. Street Level Officers get your basic set up, with maybe a few special features, and special chans,... seargants and upper level get more features and chans, and special purpose units (detectives/investigations, SWAT, etc..) get all the special ops goodies. Though with encryption,... it could be enabled for ANY of them and possibly ALL of them... (now talk about really scanner proof- EDACS Provoice Digital with ESK and Encryption turned on.) Also remember that it depends on the agency involved,.. they may decide to give top of the line radios with all features/chans/etc,... to all thier users.
