It's the USAA Academy Personal Property policy, available at all 5 Federal Academies, inexpensive, with low deductible and designed for what a cadet or mid has and where they have/take/stow their stuff, including class ring. The mid or cadet is the policy holder and applicant. An excellent alternative to claiming small, or big, losses on your family policy.
Google "USAA Academy Personal Property Policy." That takes you to the landing page for Academy, with various tabs.
I post on here in my personal capacity, but full disclosure, I work for USAA.
