Battle Management Language: History, Employment and NATO Technical Activities
Battle Management Language: History, Employment and NATO Technical Activities Mr. Kevin Galvin Quintec Mountbatten House, Basing View, Basingstoke Hampshire, RG21 4HJ UNITED KINGDOM [email protected] ABSTRACT This paper is one of a coordinated set prepared for a NATO Modelling and Simulation Group Lecture Series in Command and Control – Simulation Interoperability (C2SIM). This paper provides an introduction to the concept and historical use and employment of Battle Management Language as they have developed, and the technical activities that were started to achieve interoperability between digitised command and control and simulation systems. 1.0 INTRODUCTION This paper provides a background to the historical employment and implementation of Battle Management Languages (BML) and the challenges that face the military forces today as they deploy digitised C2 systems and have increasingly used simulation tools to both stimulate the training of commanders and their staffs at all echelons of command. The specific areas covered within this section include the following: • The current problem space. • Historical background to the development and employment of Battle Management Languages (BML) as technology evolved to communicate within military organisations. • The challenges that NATO and nations face in C2SIM interoperation. • Strategy and Policy Statements on interoperability between C2 and simulation systems. • NATO technical activities that have been instigated to examine C2Sim interoperation. 2.0 CURRENT PROBLEM SPACE “Linking sensors, decision makers and weapon systems so that information can be translated into synchronised and overwhelming military effect at optimum tempo” (Lt Gen Sir Robert Fulton, Deputy Chief of Defence Staff, 29th May 2002) Although General Fulton made that statement in 2002 at a time when the concept of network enabled operations was being formulated by the UK and within other nations, the requirement remains extant. -
Early Telecommunication and the Birth of Telegraphy in Malta
Early Telecommunication and the Birth of Telegraphy in Malta Mario Aloisio [email protected] Abstract: This paper reviews the birth of telegraphy and its take-up in Malta before the advent of radio. The driving force behind the adoption of a number of signalling methods and the telegraph in Malta was the militia, but a means of effective communication was also important for trade and as a warning system against unwanted intruders. Foreign, diplomatic, and news correspondence became possible after submarine cables linking Malta to mainland Europe were laid in the 1860s. Keywords: Telecommunications; electric telegraph, semaphore, submarine cables Introduction he Maltese archipelago has been the focus of attention of many powers who, at different periods, sought to capture and rule the Tislands. The Carthaginians, Romans, Arabs, Normans, French, and British, among others, all left their mark on these tiny islands. The Knights Hospitaller, a military religious order of St John now known as the Knights of Malta, settled in Malta in 1530 when Emperor Charles V of Sicily offered it to them after they had been driven out of Rhodes by Suleiman I. In 1798 the last grand master of the knights surrendered to Napoleon when the latter captured Malta on his way to Egypt. The French occupation was brief, the British taking over just two years later. Malta was made a British colony in 1813 and became independent in 1964. In view of Malta’s strategic location and therefore its importance as a military base and a place for international trade, the knights of St Symposia Melitensia Number 10 (2015) SYMPOSIA MELITENSIA NUMBER 10 (2015) John built impressive forts and bastions and improved upon existing defence structures. -
A New Morse Code Scheme Optimized According to the Statistical Properties of Turkish

The code book constructed by Vail was optimized according to the statistical properties of English. In this study, we propose a new code book optimized for Turkish and demonstrate that it is information-theoretically possible to achieve about a 10% improvement throughout the coding of Turkish texts by means of our proposal. The outcomes of this might serve as a basis for potential (academic and/or applied) Turkish language-specific lossless data compression studies. Key words: Information theory, source encoding, Morse code, language statistics, data compression 1. Introduction Morse code is a method of transmitting textual information as a series of on–off signals (e.g. tones, lights, clicks), which can be directly interpreted by a skilled listener or observer. This listener or observer might be either a human individual with the knowledge of the code book, or special equipment in which the code book and its encoding/decoding rules are embedded. -
Decoding the Civil War: Engaging the Public with 19Th Century Technology & Cryptography Through Crowdsourcing and Online Educational Modules
The Huntington Library, Art Collections & Botanical Gardens Proposal to the National Historic Publications and Records Commission Decoding the Civil War: Engaging the Public with 19th Century Technology & Cryptography through Crowdsourcing and Online Educational Modules Project Summary 1. Purposes and Goals of the Project The American Civil War is perpetually fascinating to many members of the public. The goal of this project is to use the transcription and decoding of Civil War telegrams to engage new and younger audiences using crowdsourcing technology to spark their curiosity and develop new critical thinking skills. The transcription and decoding will contribute to national research as each participant will become a “citizen historian” or “citizen archivist.” Thus the project provides a model for long-term informal and formal education programs and curricula as it can be used even after the transcription and decoding is completed as a teaching model for students in inquiry-based learning. The Huntington Library respectfully requests a two-year grant from the National Historic Publications and Records Commission (NHPRC) to provide partial funding for a consortium project that draws together the expertise of four different organizations—The Huntington Library, the Abraham Lincoln Presidential Library and Museum, North Carolina State University, and, through the University of Minnesota, Zooniverse.org (a non-profit devoted to citizen science)— each bringing unique expertise to a collaboration among libraries, museums, social studies education departments, and software developers with the following goals: 1) Engage new and younger audiences by enlisting their service as “citizen archivists” to accelerate digitization and online access to a rare collection of approximately 16,000 Civil War telegrams called The Thomas T. -
Louisville Kentucky During the First Year of the Civil
LOUISVILLE, KENTUCKY DURING THE FIRST YEAR OF THE CIVIL WAR BY WILLIAM G. EIDSON Nashville, Tennessee During the first eight months of 1861 the majority of Kentuckians favored neither secession from the Union nor coercion of the seceded states. It has been claimed that since the state opposed secession it was pro-Union, but such an assertion is true only in a limited sense. Having the same domestic institutions as the cotton states, Kentucky was con- cerned by the tension-filled course of events. Though the people of Kentucky had no desire to see force used on the southern states, neither did they desire to leave the Union or see it broken. Of course, there were some who openly and loudly advocated that their beloved commonwealth should join its sister states in the South. The large number of young men from the state who joined the Con- federate army attest to this. At the same time, there were many at the other extreme who maintained that Kentucky should join the northern states in forcibly preventing any state from withdrawing from the Union. Many of the moderates felt any such extreme action, which would result in open hostility between the two sections, would be especially harmful to a border state such as Kentucky. As the Daily Louisville Democrat phrased it, "No matter which party wins, we lose." 1 Thus moderates emphasized the economic advantages of a united country, sentimental attachment to the Union, and the hope of compromise. In several previous crises the country had found compromise through the leadership of great Kentuckians. -

Media Technology and Society
MEDIA TECHNOLOGY AND SOCIETY Media Technology and Society offers a comprehensive account of the history of communications technologies, from the telegraph to the Internet. Winston argues that the development of new media, from the telephone to computers, satellite, camcorders and CD-ROM, is the product of a constant play-off between social necessity and suppression: the unwritten ‘law’ by which new technologies are introduced into society. Winston’s fascinating account challenges the concept of a ‘revolution’ in communications technology by highlighting the long histories of such developments. The fax was introduced in 1847. The idea of television was patented in 1884. Digitalisation was demonstrated in 1938. Even the concept of the ‘web’ dates back to 1945. Winston examines why some prototypes are abandoned, and why many ‘inventions’ are created simultaneously by innovators unaware of each other’s existence, and shows how new industries develop around these inventions, providing media products for a mass audience. Challenging the popular myth of a present-day ‘Information Revolution’, Media Technology and Society is essential reading for anyone interested in the social impact of technological change. Brian Winston is Head of the School of Communication, Design and Media at the University of Westminster. He has been Dean of the College of Communications at the Pennsylvania State University, Chair of Cinema Studies at New York University and Founding Research Director of the Glasgow University Media Group. His books include Claiming the Real (1995). As a television professional, he has worked on World in Action and has an Emmy for documentary script-writing.
