What will wave 1 replace for GCSS-army?

Wave 1 of the Global Combat Support System-Army (GCSS-Army) is designed to replace the legacy logistics and supply chain systems, specifically the Standard Army Retail Supply System (SARSS) and the Army's Logistics Modernization Program (LMP). It aims to enhance the efficiency and accuracy of logistics operations by integrating supply chain management into a single, unified system. This transition is expected to provide real-time visibility and improved decision-making capabilities for Army logistics.
