Final answer:
The second validator on an e581 for operational loads excluding CAD/PAD is an authorized individual responsible for verifying the form after the initial validator.
Step-by-step explanation:
The question refers to a military procedure involving the validation process for an e581, which is likely a form or checklist associated with operational loads that do not include Cartridge Actuated Devices/Propellant Actuated Devices (CAD/PAD). In military operations, the second validator is usually an authorized individual who verifies and confirms the accuracy and completeness of the form or checklist after the initial validator. This process is crucial for ensuring that operational loads, which could include equipment, supplies, or munitions excluding CAD/PAD, are correctly accounted for and safely handled.
It is important to note that the specific identity or rank of the second validator can vary depending on the branch of the military, the specific operation, or the requirements set out by each unit's standard operating procedures. For detailed and accurate information, one would need to refer to the specific military branch's documentation or guidance materials.
