Staff (military)

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.

Military staff functions

Information management

One of the key purposes of a military staff is to provide accurate, timely information (which includes the results of contingency planning) on which command decisions are based. A goal is being able to suggest approaches or help produce well-informed decisions that will effectively manage and conserve unit resources.

In addition to generating information, the staff also manages the flow of communication within the unit and around it. While controlled information flow toward the commander is a priority, those useful or contingent in nature are communicated to lower-level units and/or through their respective staffs. If the information is not pertinent to the unit, it is redirected to the command level which can best utilize the condition or information.

Soviet submarine S-2

S-2 was a Soviet S-class submarine. In early 1940, it entered Swedish territorial waters in the Sea of Åland where it hit a Swedish naval mine, and sank on January 2, 1940 with the loss of all 50 crew members.

Wreck discovery

A search for the submarine wreck was begun in April 1999 by a team of divers from Sweden and Åland. According to the Military Archives of Sweden, the submarine hit the mine in Swedish territorial waters, but the Finnish archives specify the sinking occurred on Finnish territorial waters. The uncertainty of position necessitated a prolonged search. The diving team finally discovered the wreck inside Swedish territorial waters. One member of the diving team, Ingvald Eckerman, is a grandson of J. A. Eckerman who, as the lighthouse-keeper of the lighthouse at Märket, witnessed the submarine sinking in 1940.

The wreck will be emptied of munitions during the summer of 2012.
