Advanced Combat Man System 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 . " In a future deployment , the section commander and two commanding officers are to be equipped with the ACMS system as a part of honing urban operation capabilities . History . The ACMS was first developed in 1998 as a joint project by the Singaporean Army and by the Defence Science and Technology Agency ( DSTA ) alongside ST Electronics and ST Kinetics under a Technology Exploration and Demonstration initiative in order to assess the possibility of simplifying capability and integration issues . It was succeeded in 2002 with a three - year Technology Consolidation and Development effort . Trials took place in 2006 with funding allocated to the Integrated Concept Development and Demonstration stage , which permitted the acquisition of 60 ACMS sets and ACMS sets and two CCIS equipped AFV platforms . Further trails took place in 2008 when Singaporean soldiers conducted live exercises at the Murai Urban Training Facility . ST Electronics was chosen to be the main contractor responsible for the eventual production of the ACMS . Research and development of the ACMS was completed by 2012 . Field tests began in January and March 2010 when two Singaporean Army battalions were equipped with ACMS gear . Design . The challenge with the creation of ACMS was the stature of the average Singaporean soldier , considering that they are smaller than other races . The three modular variants consist of the Basic Fighting System , which is focused on fighting capabilities . The Full Fighting System equips commanders on the field , but has significant C2 capabilities . The Hand Held System which works with the Full Fighting System , which is carried by a commander ’ s aide , providing notebook hosted capabilities , which in trials used a Panasonic Toughbook , for use in stationary mission planning tasks , where greater screen size is necessary and a more complex input device can be used . The main weapon used under the ACMS is the SAR 21 ' s Modular Mounting System variant . For communications , ACMS uses Selex Soldier Personal Radio systems with a noise reduction system to protect the hearing of soldiers . In various trials done initially , the helmet mounted display was cited to be a hindrance in aiming and moving . Currently , alternatives are being studied , which includes see through HMDs and membrane displays . Components . The components of the ACMS consist of Soldier Computer , Weapon , Head Mount Display , Power , Communications and Navigation sub - systems . An integrated Load Bearing Vest and a hydration bladder are also included , the former being outfitted with armored plates . Variants . ACMS . The first variants of the ACMS system , it had a total weight of 25 kilograms . The weight proved to be bothersome since it forced wearers to move less than one kilometer in the field . A 2002 revision reduced the weight to 12 . 5 kilograms . Currently , ACMS includes a soldier computer subsystem , including a wearable computer and power pack , the communications subsystem supporting wireless radio and data connectivity through mesh networking , full color OLED based helmet mounted display and active noise diction hearing protection , indoor and outdoor navigation system with GPS support , and weapon - mounted camera with an ITL MARS reflex sight . ACMS Lite . Currently undergoing development , the ACMS Lite has latest ARM processor and mobile communications technology to enhance networking and situational awareness capability . The ACMS Lite also includes a smartphone portable device providing mesh - networking communications , processing and display of situational awareness and support of C2 applications . It will also include fabric cabling integrated into the vest , offering more reliable and lightweight , low power solution . It ' s designed for use by team leaders and their members .
