How many SHL system UTCs should Services personnel request during the planning stage?

During the planning stage, Services personnel should request two SHL (Services Headquarters Location) system UTCs (Unit Type Codes). This number is optimal because it ensures comprehensive coverage of the requirements necessary to support operations or activities while taking into account potential variations in needs or contingencies. By requesting two UTCs, Services personnel can account for both primary and secondary operations, which allows for flexibility and a more robust support structure. This approach also aids in risk management, ensuring that resources are available to adapt to changing circumstances while still fulfilling mission objectives effectively.
