With the reduction of the size of the ROC armed forces in recent years, the Army has endured the largest number of cutbacks as ROC military doctrine has begun to emphasize the importance of offshore engagement with the Navy and Air Force. Subsequent to this shift in emphasis, the ROC Navy and Air Force have taken precedence over the ROC Army in defense doctrine and weapons procurement. Recent short-term goals in the Army include acquisition and development of joint command and control systems, advanced attack helicopters and armored vehicles, Multiple Launch Rocket System and field air defense systems. The Army is also in the process of transitioning to an all volunteer force.
