Which operation involved Marine deployments to Kosovo in 1999?

Operation Allied Force was the NATO-led military operation that took place in 1999 and involved military action against the Federal Republic of Yugoslavia in response to the humanitarian crisis in Kosovo. The primary objective was to stop the ethnic cleansing and human rights abuses against ethnic Albanians in Kosovo. This operation included the deployment of Marine forces as part of a broader coalition aimed at stabilizing the region and providing humanitarian assistance.

The context of the operation highlights its significance within the framework of international military interventions during the 1990s, marked by a focus on protecting civilians and responding to crises through collective security measures. This contrasts sharply with the other operations listed, which pertain to different conflicts and contexts, such as the wars in Iraq and the Middle East.
