Also headquartered at Saigon, BD 222, a smaller battalion with just six combat companies, was in turn assigned to the General Reserve (Vietnamese: "Tổng dự trữ") of the National Police as a quick reaction unit that could be deployed nationwide, being tasked with specific missions and reinforcement duties. Engaged in Saigon during the Tet in 1968, the field policemen of BD 222 succeeded in flushing out the VC "Sappers" (Vietnamese: "Đắc Cộng") entrenched in the National Radio Broadcasting Station building, located a few hundred meters away from the American Embassy, but also fought elsewhere. Between 1968 and 1975, the Battalion's combat companies were deployed at various times and locations throughout the country, engaging in defensive and offensive operations in conjunction with other National Police or ARVN units at Huế, Da Nang, Bình Định, Tuyên Duế, Gia Định, Long An, Biên Hòa, and Phú Quốc Island. When the city of An Lộc was besieged in April 1972 during the Easter Offensive by three People's Army of Vietnam (PAVN) armoured divisions, BD 222 was rushed in to bolster the city's defenses and successfully held its ground against repeated assaults by enemy tanks.
