What event reinstated the policy concerning family member separation?

The event that reinstated the policy concerning family member separation is rooted in the tragic circumstances surrounding the death of the Sullivan Brothers during World War II. The Sullivan Brothers, five siblings serving on the USS Juneau, were all killed when their ship was sunk, which prompted the Navy to reconsider its policies regarding the assignment of family members to the same ship or unit. Following this incident, the Navy implemented the "Sullivan Law," which aimed to prevent such a loss of life within military families by reducing the likelihood of multiple siblings serving together in combat situations. This policy was a direct response to the profound impact of their loss and emphasizes the Navy’s commitment to the welfare of servicemembers and their families.
