The Criminal Law Department at The Judge Advocate General's Legal Center and School, US Army, (TJAGLCS) produces this deskbook as a resource for Judge Advocates, both in training and in the field, and for use by other military justice practitioners. This deskbook covers many aspects of military justice, including Substantive Military Justice (Volume I), Pre-and Post-Trial Procedure (Volume II), Trial and Evidence (Volume III), and Special Topics in Military Justice (Volume IV). The deskbook is neither an all-encompassing academic treatise nor a definitive digest of all military criminal caselaw. Practitioners should always consult relevant primary sources, including the decisions in cases referenced herein. Nevertheless, to the extent possible, it is an accurate, current, and comprehensive resource. Readers noting any discrepancies or having suggestions for this deskbook's improvement are encouraged to contact the TJAGLCS Criminal Law Department. Current departmental contact information is provided at the back of this deskbook.
