Which pre-collection tasks may the Commander delegate to the UPL?

The pre-collection tasks that a Commander may delegate to the UPL primarily involve the organizational and preparatory aspects of the urinalysis testing process. These tasks include selecting observers who will witness the collection process, conducting the commander briefing to ensure all personnel are informed about the testing procedures and protocols, and selecting the personnel who will be tested.

By delegating these responsibilities, the Commander allows the UPL to take charge of the operational elements that contribute to the effective execution of the urinalysis program while maintaining oversight and authority within the chain of command. This delegation is essential to ensure that the testing process is conducted fairly and without bias, while also ensuring proper communication and understanding of the process among unit members.

The other options present tasks that are more operationally focused or involve direct engagement with the testing process itself, which are typically not delegated to the UPL by the Commander to maintain control over the integrity of the testing.
