Final answer:
The correct sexual assault reporting option for DoD civilian employees and their family dependents aged 18 or older is Restricted Reporting, allowing for confidentiality and access to support without initiating a formal investigation. This is separate from the previously enacted 'Don't Ask Don't Tell' policy.
Step-by-step explanation:
The only sexual assault reporting option available to DoD civilian employees and their family dependents 18 years of age or older is B) Restricted Reporting. Restricted Reporting allows a service member or DoD civilian who is a victim of sexual assault to confidentially disclose the details of their assault to specifically identified individuals (e.g., Sexual Assault Response Coordinator, Victim Advocate, or a healthcare provider) without triggering an official investigation. This is particularly important for victims who may wish to seek support and healthcare services without initiating a formal command-directed investigation.
It's important to note that this question is distinct from the Don't Ask Don't Tell (DADT) policy, which pertained to the eligibility of homosexuals desiring to serve in the US military. DADT was a policy that disallowed military personnel from discriminating against or harassing closeted homosexual or bisexual service members or applicants, while barring openly gay, lesbian, or bisexual persons from military service. This policy was abolished in 2011, and is not directly related to the current protocols for reporting sexual assault within the DoD, which have evolved to better support victims.
