What document adds qualification records for operators?

The correct answer is DA Form 348, which is the primary document used for recording qualifications, training, and evaluation of operators of military vehicles and equipment. This form serves as a significant record that tracks an operator's proficiency and competence in operating specific equipment, ensuring that all operators meet the required standards.

DA Form 348 is essential for maintaining safety and operational readiness within the military by certifying that personnel are adequately trained and qualified to perform their duties. This documentation allows for effective management of operator qualifications and is crucial for ensuring that only those who have met the necessary training criteria are authorized to operate military vehicles and equipment.

In comparison, while DA Form 625 is used for recording hazardous duty or special qualifications, it does not specifically focus on operator training and qualifications. DA Form 214 is a certificate of release or discharge from active duty and is not related to operator qualifications. DA Form 2992 is utilized for physical profiles, including medical evaluations and restrictions, rather than documenting qualifications for operators. Therefore, DA Form 348 stands out as the appropriate choice for adding qualification records for operators.
