The Vienna Document is a confidence- and security- building measure in which members of the Organization for Security and Cooperation in Europe (OSCE) agree to inspections and data exchanges in order to increase transparency of their conventional forces. With
Background: The Vienna Document encompasses the goals of the Helsinki Final Act Decalogue of 1975 and incorporates them into a politically binding document. The Helsinki Final Act principles created the initial confidence- and security- building measures that would be elaborated upon, first in the Stockholm Document (1986) and later in the first Vienna Document. The first document, Vienna Document 1990, would have successors in Vienna Documents 1992, 1994, and 1999. All of the Vienna Documents have sought to strengthen the transparency and openness in the OSCE area.

During the most recent Annual Implementation Assessment Meeting (AIAM), held March 2-3, 2010, the OSCE’s Conflict Prevention Centre reported that the Vienna Document’s “overall implementation level has remained relatively stable and high."  Per the Meeting’s Consolidated Summary, although the number of inspections and evaluations fell in 2009 from their 2008 levels, the number was still above the five-year average. There is some speculation that the economic conditions facing Vienna Document countries could play a part in the lower numbers.
The 2010 State Department report on Adherence to and Compliance with Arms Control, Nonproliferation, and Disarmament Agreements and Commitments, which considered treaty and agreement compliance from January 1, 2004 to December 31, 2008, found that “compliance with VD99 has been good.”  The report acknowledged that some states did not submit their information for the December meeting but that “most” of the States eventually submitted the required paperwork.
In regards to the sharing of information under the Vienna Document, there was conversation at the March 2010 AIAM that changes may need to be made to the document because of new technology, capabilities, and military structures that have not been accounted for.
Information Exchange: Under the Vienna Document, countries agree to an Annual Exchange of Military Information where information regarding “military forces concerning the military organization, manpower and major weapon and equipment systems” will be shared with other member states.  A country that plans to change the structure of their military forces for a period longer than 21 days (such as increasing the size of a combat unit) reports the change to other states. States also share information about their weapon systems and if there are plans to deploy new systems (if so, countries share information about these systems). Under Article II, countries are also expected to provide information regarding their defense planning. Under a general considerations report, a state provides information regarding their military structure (including specific unit and formation information), major weapons and equipment systems, and their hardware. The specific equipment that is covered by the Vienna Document can be found in Article I.

Number of Submitted Reports (Defense Planning)
The Vienna Document also says that states should inform other states if “certain military activities” will take place, which means a military activity will be subject to notification whenever it involves at any time during the activity:
- at least 9,000 troops, including support troops, or
- at least 250 battle tanks, or
- at least 500 armored combat vehicles, as defined in Annex III, paragraph (2), or
- at least 250 self-propelled and towed artillery pieces, mortars and multiple rocket-launchers (100 mm calibre and above). 
States also can invite other member states to militarily significant actions for observation purposes.  There are some constraints on states, including limits on the number of exercises that can be carried out within a specific timeframe under certain conditions. 
If a Vienna Document state has concerns about a militarily significant action, they can request an explanation of the action from the party responsible. If there are concerns after an explanation is offered, the concerned state can request a meeting with the acting party. Participation in the meeting will be open to any states interested in the action. Either party can also request a meeting of all states, which would be conducted as a joint Permanent Council and Forum for Security Cooperation meeting, where recommendations from states will be considered.
Process: The Vienna Document 1999 encourages countries to host visits to military facilities, create military contacts, and hold joint exercises and demonstrations of military equipment as ways of increasing confidence between states.  By November 15, states are expected to submit a schedule of prior notification military activities for the next year. According to the Consolidated Summary of the 19th Annual Implementation Assessment Meeting , held March 3-4, 2009, “a total of 109 inspection visits in 2008 had resulted in more than 1,000 arms control personnel having the opportunity to meet their counterparts and improve their relations.”

Number of Countries Hosting Evaluation Visits
Number of Inspection Visits
Under the Document, states can host three inspections on their territory per year and do not have to exceed that limit if they do not wish. Inspection teams observe notable military activities. In addition to inspection visits, there are also evaluation visits, which verify data that is part of the information exchange. A state must host at least one and no more than 15 evaluation visits a year (number of visits is determined by number of units). 
Article XI calls for an Annual Implementation Assessment Meeting where states will have the opportunity to discuss questions of implementation, operations, and questions that may have arisen from information that has been exchanged. The meeting, hosted by the Forum for Security Cooperation, is also an opportunity to discuss confidence- and security- building measures. If a state has not offered their data at the Annual Exchange of Military Information, held no later than December 15, they are expected to offer an explanation as to why it has not been submitted and an expected date for contribution.
