The HIMAT (Hypervelocity Intelligent Missile, Anti-tank) is a man-portable "brilliant" weapon with a range greater than 5 km. An extremely versatile weapon, it gives commanders many options for deployment and use.

The main element is an 11.3 kg single-shot, self-contained, disposable launcher equipped with bipod and baseplate. The bipod can be set for any angle between 0 and 90 degrees.

Defensive use-When used defensively, the HIMAT can be set for "Command" or "Automatic". In either case, one or more launchers are connected via cables to the Fire Control Unit, an intelligent computer system which receives data from the local sensor matrix, including motion trackers, IR scanners, LIDAR, RADAR, and robotic sentries. The FCU can also be linked to command-wide units such as surveillance drones, forward observers, or satellites. The FCU analyses all available sensor data and upon positively identifying a threat, it will lock on with one or more missiles and prepare to launch.

The next action depends on whether the FCU is set to "Command" or "Automatic". In "Command" mode, an operator constantly monitors the designated anti-tank area. When a threat is identified, the FCU will show a "Target Lock", allowing the operator to either authorize a missile launch or request further IFF (Identification, Friend or Foe) interrogation. In "Automatic" mode, the FCU will work through it's target ID protocols to ensure it has identified an enemy, then it will automatically launch one or more missiles.

Offensive use-The HIMAT can be used in direct fire mode by plugging an infantry SR-90 Target Aquisition Sight into the launcher. The SR-90 combines passive IR with an active ultrasonic motion tracker and has enough cable to distance the operator up to 150m away from the launcher. Once the operator has a target locked-on, the information from the sensors is passed to the missile, which is launched by the operator.

HIMAT missile-The missile itself is a small two-stage round with a multi-sensor seeker. Upon launch, the missile is ejected from it's tube vertically by the first-stage motor where it's control vanes orient it towards the target. The second-stage then fires, accelerating the missile nearly instantaniously to Mach 4.5. The seeker consists of a millimeter-wave radar and an aerial that allows "home-on-jam" capabilities. The seeker scans the target during it's approach and determines it's exact type and configuration from memory. If the target turns out to be friendly, the missile will steer itself away and self-destruct. If the target is hostile, the seeker will determine the optimum impact point and steer the missile towards it.

The warhead is comprised of a 15 cm tungsten rod surrounded by high explosive. The explosive is detonated just before impact, launching the rod into the target's armor, similar to a tank SABOT round. The combination of the missile's hypervelocity and the explosive force allows the tungsten rod to penetrate all but the strongest armor.

The HIMAT has some success against aerial targets, such as low-flying dropships, helicopters, and VTOL aircraft. A multi-purpose warhead is being designed for use against both ground and aerial targets.

A new infantry sight that replaces the motion tracker with a millimeter-wave radar is being introduced to allow use against non-moving targets such as bunkers and supply dumps. However, the new sight will only be effective once the new multi-purpose warhead is introduced.
