Which form is used to apply for a security clearance in the military?

The form used to apply for a security clearance in the military is the Standard Form 86 (SF 86). This comprehensive form is specifically designed for individuals seeking a security clearance and includes detailed questions about personal history, financial status, criminal activity, and other factors that may affect eligibility for access to classified information.

Completing the SF 86 is a critical step in the background investigation process, as the information provided is assessed to evaluate the individual’s reliability, trustworthiness, and loyalty to the United States. This information is vital for ensuring that those with access to sensitive information can be trusted to handle it appropriately.

The other forms mentioned serve different purposes; for example, NAVPERS 2070/64 is related to officer evaluations, DD Form 214 is a discharge document, and DD Form 2807-1 is a report of medical history, which are not involved in the security clearance application process.
