In previous wars, military vehicles could rush to the front and then safely stop at the rear to refuel. But in Iraq, fighting is everywhere, and supply convoys are always in danger. Hybrid military vehicles can reduce the number of supply fleets. The Army is testing several hybrid vehicles using Hummer chassis at several proving grounds in the United States.

The Marine Corps is testing another vehicle, RST-V, which is a light vehicle made by General Dynamics, and each wheel is equipped with an electric engine. Although the durability of this axle drive mode has yet to be verified, this design means improving the safety of soldiers.

Each wheel of RST-V is equipped with an engine, which means that even if one wheel is destroyed, the vehicle can still run. The bulky transmission shaft and other parts are eliminated, eliminating the danger that these parts will become projectiles when the vehicle encounters mines or bombs.

Hybrid electric vehicles help the army to realize the increasingly urgent demand for energy saving. This car may also have the following advantages:

First of all, the movement is almost silent. When soldiers don't want engine noise to expose their whereabouts, they can only rely on battery drive.

Secondly, it can be used as a power supply. Hybrid electric vehicle can provide electric energy for field command post without loading generator, and its rechargeable battery can do this.

Finally, the acceleration ability is strong. The test shows that the short-term acceleration ability of hybrid electric vehicle is better than that of ordinary Hummer.

In 2009, the production of this "Hummer" substitute began, and the production began at 20 1 1.

Hybrid power systems will eventually be replaced by more advanced power systems, such as hydrogen fuel cells.
