East Lansing units begin with the number 2, followed by the type of unit (ADAM=One Man, BOSTON=Two Man, CHARLIE=Community Policing, DAVID=Detective, MARY=Motorcycle, BIKE=Bicycle, or K9) then thier sector number. Example 2Adam31 would be an East Lansing one man car in sector 3.
MSU units begin with the number 6, followed by the type of unit as stated above, then thier badge number since they don't have sectors. Example 6K947 would be an MSU K9 unit, badge #647.
If you hear MSU talking on thier tactical channel for special events they just use badge numbers, which are all in the 600 series.
This numbing scheme is also the same for Meridian Twp police on 460.1 as they are also dispatched by the East Lansing Communication Center, but all of thier units begin with the number 9.
