The Land 75 Phase 3.4 Battlefield Command Support System (BCSS) project will provide a digital command and control support system to enhance combat capability of the Australian Army through supporting timely and quality decision-making in the land tactical environment. The BCSS project will also deliver Battle Management Systems (BMS) to over 1000 field vehicles, including; Bushmaster Protected Mobility Vehicles (PMV), M113 Armoured Personnel Carriers (APC), G-Wagons, Macks and Unimogs. The BMS is a computer-based command and control system designed to enhance the tactical commanders Situational Awareness and ability to execute operations. The BMS consists of software that is simple and intuitive to use; and hardware that can survive in the land tactical [combat] environment.

The BMS is the central component of the Battle Group and Below Command, Control and Communications System (BGC3) that is being jointly delivered by the Land 75 Phase 3.4, Land 125 Phase 3A and JP 2072 Phase 1 projects, and will incorporate a mobile, data capable communications system and be able to exchange combat information with BCSS and other BMS. The BGC3 will form the basis of a land combat identification (Blue Force Tracking) system by providing commanders with a 'real-time' Situational Awareness display of friendly force locations.
