Active duty personnel in the three Nigerian armed services total approximately 76,000. The Nigerian Army, the largest of the services, has about 60,000 personnel deployed in two mechanized infantry divisions, one composite division (airborne and amphibious), the Lagos Garrison Command (a division size unit), and the Abuja-based Brigade of Guards. It has demonstrated its capability to mobilize, deploy, and sustain battalions in support of peacekeeping operations in Liberia, Yugoslavia, Angola, Rwanda, Somalia, and Sierra Leone. The Nigerian Navy (7,000) is equipped with frigates, fast attack Pratt, convenes, and coastal patrol boats. The Nigerian Air Force (9,000) flies transport, trainer, helicopter, and fighter aircraft, but most are currently not operational. Nigeria also has pursued a policy of developing domestic training and military production capabilities. After the imposition of sanctions by many Western nations, Nigeria turned to China, Russia, North Korea, and India for the purchase of military equipment and training.
