[FedCom] US Marshals Service Freqs & Ops

[Dave J]

Used to be interesting hearing the US. Marshals and the Air Force security
folks on 143.095  escorting the warhead (re-entry vehicle) convoys when they
moved warheads to and from the minuteman missile sites that were here in SD.
Happened pretty often and was a real max effort security-wise each time.
