32 C.F.R. § 536.110
To enable USARCS to properly discharge its claims responsibilities under the applicable SOFAs, it must be notified of all incidents, including off-duty incidents, in which members of a foreign military force or civilian component are involved. Any member or employee of the U.S. armed services who learns of an incident involving a member of a foreign military force or civilian component resulting in personal injury, death, or property damage will immediately notify the judge advocate (JA) or legal officer at the installation or activity to which such person is assigned or attached. The JA or legal officer receiving such notification will in turn notify the Commander USARCS. If the member is neither assigned nor attached to any installation or activity within the United States, the Commander USARCS, will be notified.
