Combat vehicle

"Ground combat vehicle" redirects here. For the U.S. Army's combat vehicle program, see Ground Combat Vehicle.

An M-ATV, a mine protected vehicle.

A combat vehicle, also known as a ground combat vehicle, is a self-propelled, weaponized military vehicle used for combat operations. Combat vehicles can be wheeled or tracked.

Design

Automation

The Armed Robotic Vehicle variant of the MULE

The automation of human tasks endeavors to reduce the required crew size with improvements in robotics. Enhancements to automation can help achieve operational effectiveness with a smaller, more economical, combat vehicle force.^[1] The automation of combat vehicles has proved to be difficult due to the time latency between the operator controlling the vehicle and the signal being received. Unlike air forces, ground forces must navigate the terrain and plan around obstacles. The rapid tactical implications of operating a weaponized vehicle in a combat environment are great.^[2]

Countermeasures

Use of titanium armor on combat vehicles is increasing. The use of titanium can lighten the vehicle's weight.^[3]

Appliqué armor can be quickly applied to vehicles and has been utilized on the U.S. Army's M8 Armored Gun System.^[3]

Fire suppression

Contemporary combat vehicles may incorporate a fire-suppression system to mitigate damage from fire. Systems can be employed in the engine and crew compartments and portable systems may be mounted inside and outside the vehicle as well.

Automatic fire-suppression systems activate instantaneously upon the detection of fire and have been shown to significantly improve crew survivability. Halon fire suppression systems quickly inundate an affected fire breach with a flood of halon to extinguish leaking fuel. Halon remains necessary for crew compartment fire suppression due to space and weight constraints, and toxicity concerns. Nitrogen systems take up about twice as much space as a comparable halon unit. Germany uses this system as a replacement for its halon system. Some systems, such as Germany's previous extinguisher, have a second shot of suppressant to mitigate re-ignition or the effects of a second hit.^[4]

Though not as instantaneous, portable crew-operable extinguishers are also used inside and outside the vehicle. Typically, portable extinguishers use a CO₂ agent instead of the halon agents used in the past. CO₂ can become lethal to vehicle occupants if it accumulates into a deadly concentration. The U.S. Army has adopted a replacement formula consisting of 50% water, 50% potassium acetate. Alternatives such as powder formulas also exist.^[5]

Crew

Hygiene upkeep is difficult when operating a combat vehicle.^[6]

Mobility

Tracked combat vehicles are suited for heavy combat and rough terrain. Wheeled combat vehicles offer improved logistical mobility and optimized speeds on smooth terrain.

Silent watch is a role that requires that all mission requirements be met while keeping acoustic and infrared signature levels to a minimum. For this reason, silent watch often requires the vehicle to operate without use of the main engine and sometimes even auxiliary engines. Many modern combat vehicles often have electronic equipment that cannot be supported solely with auxiliary batteries alone. Auxiliary fuel cells are a potential solution for covert operations.^[7]

Networking

Force trackers are still not as prevalent as in the air force but still is an essential component of combat vehicles.^[8][9]

In the mid-'90s, U.S. weapon developers envisioned a sophisticated communication network where positions of enemy and friendly forces could be relayed to command vehicles and other friendly vehicles. Friendly vehicles could transmit enemy positions to friendly combat vehicles in combat range for efficient annihilation of the enemy. Logistics support could also monitor front-line combat vehicle fuel and ammunition statuses and move in to resupply depleted vehicles.^[10]

Weaponry

Combat vehicles weapons are primarily designed for engaging other vehicles at long distances and are not optimized for destroying non-traditional targets like car bombs.^[11]

History

Silent watch is becoming an increasingly important combat vehicle application.^[7]
