More About The TERREX Infantry Carrier Vehicle (ICV) Team

The introduction of the family of 8x8 wheeled TERREX Infantry Carrier Vehicles (ICV) marks a significant milestone in the Third Generation Army's transformation efforts as it enhances the Army's fighting and networking capabilities.

The TERREX ICV is a complex system of systems integrated platform that encompasses many technical innovations that equip the infantry with enhanced protection, mobility and firepower. Most importantly, it networks soldiers equipped with the Advanced Combat Man System (ACMS) and other air and land systems via the Battlefield Management System (BMS), thus facilitating the delivery of timely battlefield management information for better coordinated operations and fires to achieve the force multiplier effect.

The TERREX ICV family has seven variants, namely

(1) Command,
(3) Pioneer,
(4) Anti-tank Guided Missile (ATGM),
(5) Medical,
(6) Reconnaissance, Surveillance and Target Acquisition (RSTA) and
(7) STrike ObserveR Mission (STORM) variants.

The vehicle is integrated with various systems such as the Weapon Detection System (WDS), All Round Surveillance System (ARSS), Closed Hatch Driving System (CHDS), Battlefield Management System (BMS) and the Remote Control Weapon System (RCWS).

Technical Innovations Introduced by the Team

1. Intra-vehicle networking for rapid fire

The team integrated three subsystems together - BMS, WDS and RCWS - to create a closed loop sensor-shooter system that detects, locates and slews the RCWS towards enemy fire. This enables the TERREX ICV to respond
rapidly to enemy fire.

2. Inter-vehicle networking for a networked force

The team linked the BMS with the vehicle's communications system, which enables the TERREX ICV to be connected to other TERREX ICVs and external systems such as the Advanced Combat Man System (ACMS), attack helicopters and other ground systems.

With the BMS providing troops with timely battlefield information, the TERREX ICV serves as a mother ship for the troops. This allows them to optimise resources and to make coordinated responses and fires to achieve the force
multiplier effect.

Improved BMS homepage that is easier and faster to navigate

To allow troops to navigate the BMS more quickly, the team created an improved homepage for the system. This allows the soldiers to think and act swiftly in the field.

3. Enhanced safety, improved drivability and greater situational awareness with Closed Hatch Driving and All Round surveillance

Closed Hatch Driving and Surveillance System

The cameras mounted all around the TERREX ICV make up the unique Closed Hatch Driving System (CHDS) and All Round Surveillance System (ARSS). This allows troops to operate the TERREX ICV safely from within the

The three LCD screens located at the driver compartment allow the driver to select camera views in both day and night conditions. Reversing the TERREX ICV is also made easier and safer as the images from the rear camera can also be piped into the driver's LCDs.

The team is probably among the first in the world to design a closed hatch driving and surveillance system via a network of cameras. The CHDS and ARSS provide greater protection for troops especially during urban operations.

Front Camera Cleaning System

To prevent the vehicle's front and thermal cameras from getting covered by mud and sand when it travels across muddy terrain, the team created a cleaning system with pressurised water and air jets to remove mud and sand.

This simple innovation introduced by the team has helped to improve the drivability of the TERREX ICV.

360-degree Surveillance

The cameras within the ARSS also provide the crew and troopers with 360 degree situational awareness around the TERREX ICV, thereby enhancing their protection.

4. Improved Weapon Detection System that masks the vehicle's own shots

The Weapon Detection System (WDS) is an acoustic system that detects shots. The original configuration of the equipment acquired from the Original Equipment Manufacturer (OEM) picks up all shots that are fired at and around
the vehicle, including those from the vehicle itself and enemy forces. Working with the OEM, the team created an improved WDS that masks shots fired from the vehicle. These shots are not displayed on the BMS, thus eliminating
the possibility of confusion between own and enemy fires. This unique and new feature has been adopted by the OEM for their WDS.

5. Improved overturn safety for the vehicle

Instead of using conventional inclinometers to warn drivers when driving on slopes, the team maximised the use of the vehicle's navigation system by tapping its pitch and roll signals and displaying them via the Digitised Vehicle
Interface Module (DVIM) at the driver station. With this, the driver will be alerted if the vehicle reaches its overturning limit for up, down and side slopes. These alerts help to prevent overturning and enhance the safety of the troops within vehicle.

6. Enhanced navigation system

During trials, the team observed that the drivers relied heavily on the vehicle commander for driving directions as the acquired DVIM only provides waypoint arrows and a location grid on the driving screen. To overcome these issues, the team introduced raster/aerial photo maps and signals from the navigation system to the driving station to allow the vehicle's position to be reflected on the map. These features enable the driver to navigate on his own
and remove his reliance on the vehicle commander for directions.

7. First-of-its-kind Remote Control Weapon System

First-of-its-kind twin weapon Remote Control Weapon System

The team developed a twin-weapon Remote Control Weapon System (RCWS) with the 40mm Automatic Grenade Launcher and the 7.62 mm General Purpose Machine Gun. This unique combination is the first in the world.

This optical or the thermal sight on the RCWS can also be used by the vehicle and troop commanders to zoom in on specific areas of interest for surveillance, target examination, as well as target damage assessment.

Improved Man-Machine Interface

The team also enhanced the RCWS by improving and customising the Man-Machine Interface (MMI) through Human Factors Engineering1 and numerous live-firing trials. The target engagement screen and Built-in Test (BIT) features were also customised according to users' needs. The improved MMI has facilitated training, and the improved BIT features have made troubleshooting easier for the operators and technicians. These features are designed to enable them to operate the RCWS intuitively.

The Tripartite Collaboration and Roll of Each Organisation

The superior and cost effective TERREX ICV is the product of a strong tripartite relationship between the Army, DSTA and ST Kinetics. With each organisation providing unique expertise, this tight-knit tripartite relationship
represents the successful and seamless integration of Operations, Technology and Logistics or 'Ops-Tech-Log Integration'. With professionalism, hard work and commitment, solutions that meet the unique operational requirements of the SAF have been developed "on-the-fly" and within an impressive Speed-to-Market timeline of 28 months for the first delivery.


DSTA provided technical and management oversight in the multi disciplinary, complex system of systems TERREX ICV project. DSTA also played a central role in the acquisition and integration of the various systems on board the
TERREX ICV. As the overall programme manager, DSTA supervised the project management process and worked closely with the Army to understand and translate their stringent and unique operational requirements into
technical specifications. DSTA also worked closely with ST Kinetics to conduct design reviews, testing, trials and evaluation of the TERREX ICV at every stage of its development to ensure that the TERREX ICV platform met
all requirements within budget and on schedule.

The Army

The Army played a key role in determining the operational requirements for the TERREX ICV with clear demands on capability, integration of subsystem and operational workflow and procedure. These operational requirements
drove the technical solutions that are used in the vehicle.

ST Kinetics

ST Kinetics played a key role in designing, manufacturing, testing and integrating the various subsystems to provide the TERREX ICV with superior mobility, protection and fire power. ST Electronics (Info-Software Systems) also played a key role in the development of the Battlefield Management System, thus providing the platform with both intra-vehicle and inter-vehicle network capabilities.
