MSP Callsigns

[BlackSheepDue]

With the purchase of a unication G5 I've recently gotten back into following MSCOMMNET closely and started keeping track of P25 UID's and call signs. I think I have a pretty good handle on everything except the three following callsign series;

1200 - similar P25 UID series to troopers
1300- similar P25 UID series to troopers
2600 - similar P25 UID series to troopers

Can anyone shed some light on what agencies or specific job title these callsign series are associated with?

1200 is CID, 1300 is Fire Marshals, 2600 is New troopers
