What is the purpose of the TDN?
The TDN system augments the existing MAGTF communications infrastructure. It provides the commander with an integrated data network and forms the data communications backbone for MAGTF TDSs.
What is the purpose of communication within the NMCB?
Communications permit the Commander to exercise command and control over subordinate units, provide the means to remain informed of subordinate unit disposition, and enable the flow of information to higher echelon commands.
Explain the scope of the Communication and Information Security (CIS) Program?
The scope of the CIS Security Program is to prevent the loss of material or information to unauthorized persons or, more severely, to the unfriendly enemy.
Explain the proper equipment check-out procedures as it applies to CIS.
When equipment is required to support either training or operations, it will be issued using the Equipment Custody Receipt. For COMSEC material, SF 153 will be utilized. All equipment check-out forms will be maintained on file for a period of one year after the equipment has been returned.
Describe the proper handling storage and disposal of Lithium Batteries.
Storage of lithium batteries will be confined to well-ventilated, metal containers in an area in which the temperature does not exceed 130 degrees Fahrenheit. The storage area will be identified as “FLAMMABLE SOLID,” and “NO SMOKING” signs will be prominently displayed. Depleted lithium batteries will not be retained for storage. Those batteries determined to be depleted will be expeditiously submitted for disposal as hazardous waste.
