fuel cells are a potential solution for covert operations. Networking Force trackers are not as prevalent as in air forces, but are still essential components of combat vehicles. In the mid-1990s, 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. Weaponry Weapons mounted on combat vehicles are primarily designed for engaging infantry or other combat vehicles at a distance. They are often intended to be used against soft targets and may consist of weapons such as machine guns, automatic grenade launchers, or simply the presence of firing ports or armored turrets for the crew or infantry to fire their own issued weaponry from. Some combat vehicles may also carry anti-armor or anti-vehicle weaponry such as autocannons or anti-tank guided missiles. High-caliber or dedicated combat vehicles such as tanks or self-propelled weaponry may carry tank guns, multiple rocket launchers, artillery, or anti-aircraft weaponry. Most combat vehicles are not optimized for destroying non-traditional targets such as car bombs, though many may be designed to be resistant to explosives.
