Which operation is associated with the US efforts in the Persian Gulf in 1991?

The operation associated with the US efforts in the Persian Gulf in 1991 is Operation DESERT STORM. This military campaign was a significant part of the Gulf War, which aimed to liberate Kuwait after its invasion by Iraq in August 1990. Operation DESERT STORM commenced in January 1991 and involved a large-scale coalition force, which included military personnel from several nations.

During this operation, the US and its allies executed a strategic air campaign followed by a ground assault, demonstrating advanced military technology and operational strategy. The successful execution of Operation DESERT STORM played a crucial role in establishing US military presence and influence in the region post-conflict, contributing to a new strategic landscape in the Middle East.

The other operations listed do not pertain to the 1991 events in the Persian Gulf. Operation CALM RESOLVE dealt with the aftermath of the conflict, Operation REFORGER was a Cold War exercise focused on rapid reinforcements to Europe, and Operation URGENT FURY was the US invasion of Grenada in 1983. Thus, Operation DESERT STORM stands out as the definitive military operation linked to the US efforts during this period in the Persian Gulf.
