The Advanced Combat Man System (ACMS) is part of the Singapore Armed Forces's (SAF) move to integrate into 3G to progressively provide tactical units with network capabilities, including C4I capabilities in the field. The project costs about $SGD 100 Million to maintain. The head of the ACMS project is Lieutenant Colonel Jimmy Toh Yong Leng. According to him, ACMS was created to address concern of urban warfare operations, especially "key challenges in this environment were survivability, situational awareness (SA) and the avoidance of civilian casualties and collateral damage."
