Military Justice: DOD and the Coast Guard Need to Improve Their Capabilities to Assess Racial Disparities, Statement of Brenda S. Farrell, Director Defense Capabilities and Management, Testimony Before the Subcommittee on Military Personnel, Committee on Armed Services, House of Representatives [open pdf - 1MB]
From the Highlights: "The Uniform Code of Military Justice (UCMJ) was established to provide a statutory framework that promotes fair administration of military justice. Every active-duty servicemember is subject to the UCMJ, with more than 258,000 individuals disciplined from fiscal years 2013-2017, out of more than 2.3 million unique active-duty servicemembers. A key principle of the UCMJ is that a fair and just system of military law can foster a highly disciplined force. This statement provides information on 1) the collection of race and ethnicity information in the military services' databases, 2) the extent of racial disparities in investigations, disciplinary actions, and case outcomes in the military justice system, and 3) steps taken by DOD to study any identified disparities."
