The United States Army is seeking information from industry regarding existing and emerging technologies, systems, and capabilities that could fulfill the requirements for a modernized Detainee Management Accountability and Reporting (DMAR) System. The DMAR system should provide end-to-end detainee lifecycle management, from point of capture to final disposition, and include features such as biometric and biographic capture, property logging, movement tracking, and medical and legal records management. The system should also be scalable, cybersecure, and compliant with all applicable Department of Defense (DoD), U.S. Government, and international regulations governing the handling of detainees. • The DMAR system should support secure multi-domain operations and operate in both connected and disconnected modes. • The system should integrate with existing DoD systems such as the Department of Defense Automated Biometric Identification System (DoD ABIS) and the Army Intelligence Data Platform (AIDP). • The system should provide real-time situational awareness to Commanders, Legal Advisors, Intelligence Analysts, and Military Police at multiple echelons. • The system should support role-based access controls and analytics. • The system should be compliant with DoD Instruction 2310.01E and the Geneva Conventions.
