During what conflict was the HMMWV first used extensively?

The High Mobility Multipurpose Wheeled Vehicle (HMMWV), commonly known as the Humvee, was first used extensively during the Gulf War. This conflict took place from August 1990 to February 1991, and it showcased the HMMWV’s capabilities in a combat environment. The vehicle was designed to replace the Jeep and to provide a versatile platform for a variety of military functions, including troop transport, command and control, and logistical support.

The Gulf War represented the first significant deployment of the HMMWV in war conditions, where its attributes such as high mobility, off-road capability, and adaptability made it particularly valuable in the desert terrain of Iraq and Kuwait. The HMMWV quickly became a symbol of modern military logistics and transportation, demonstrating its effectiveness on the battlefield. The other conflicts listed did not feature the same level of operational usage for the HMMWV as seen in the Gulf War.
