The 1st Battalion, 12th Cavalry was deployed to Camp McGovern, Bosnia from March to September 1999 in support of Operation Joint Forge Stabilization Force (SFOR) 5B. 1-12 CAV patrolled the areas around Brčko in northern Bosnia, and enforced the Dayton Peace Accords. This rotational tour included patrolling the Zone of Separation established as a buffer between the warring factions, Weapon Storage Site (WSS) inspections and inventories, and joint patrols with other NATO units. During this rotational deployment, 1-12 CAV witnessed the final UN arbitration decision regarding control of the key city of Brčko, and the NATO airstrikes in Serbia in support of initial NATO operations in Kosovo.
