Staff (military) 参谋部
（重定向自General Staff Officer）
A military staff (often referred to as General Staff, Army Staff, Navy Staff or Air Staff within the individual services) is a group of officers and enlisted personnel that are responsible for the administrative, operational and logistical needs of its unit. It provides bi-directional flow of information between a commanding officer and subordinate military units. A staff also provides an executive function where it filters information needed by the commander or shunts unnecessary information.
