The changes in the conduct of military operations during the wars of the French Revolution were the basis for the theory of lines of operation formulated by Jomini in his Traité de grande tactique. ...The notion of lines of operation gained a new meaning that paved the way for the conceptualisation of the operational art and the transition from tactical debate to strategic thinking. Jomini's contribution to the development of strategic thought is considered from the dual perspective of the break with the military writers of the 18th century and the judgments made on the Traité by Napoleon and Clausewitz.

On 24 February 2022, Russia launched a ‘special military operation’ against Ukraine, sparking the largest conflict in Europe since the Second World War. The war is a remarkable opportunity to observe ...Russia’s military capabilities in a high-intensity conflict and to reflect on military trends witnessed in recent conflicts. Guillem Colom-Piella sets out a series of initial impressions on Moscow’s military performance in this ongoing conflict.◼
Abstract
The development of modern technology in recent years, makes the data security very big issue. To secure our data from unauthorized person, encryption is used before transmission. Various ...sensitive information is using encryption such as: e-mail messages, banking transactions, credit information and military operations. The encrypted data can be in form of text, image, voice, and video. In this paper, a proposed Hill algorithm with chaos system is used to encrypt colour RGB (Red, Green and Blue) image. The key of Hill algorithm is a square matrix. The selection of matrix key numbers is very important. Therefore, chaos system is used to generate sequences of numbers for Hill key matrix. These sequences have a property of randomness that make it very difficult for guessing. Finally, the proposed system is simulated using MATLAB, and a test image is encrypted and decrypted using proposed system successfully.
Underwater wireless communications refer to data transmission in unguided water environment through wireless carriers, i.e., radio-frequency (RF) wave, acoustic wave, and optical wave. In comparison ...to RF and acoustic counterparts, underwater optical wireless communication (UOWC) can provide a much higher transmission bandwidth and much higher data rate. Therefore, we focus, in this paper, on the UOWC that employs optical wave as the transmission carrier. In recent years, many potential applications of UOWC systems have been proposed for environmental monitoring, offshore exploration, disaster precaution, and military operations. However, UOWC systems also suffer from severe absorption and scattering introduced by underwater channels. In order to overcome these technical barriers, several new system design approaches, which are different from the conventional terrestrial free-space optical communication, have been explored in recent years. We provide a comprehensive and exhaustive survey of the state-of-the-art UOWC research in three aspects: 1) channel characterization; 2) modulation; and 3) coding techniques, together with the practical implementations of UOWC.

The war in Ukraine has highlighted that, although the major European powers are among the largest defence spenders, they cannot efficiently translate their financial resources into military power. ...Bence Nemeth argues that South Korea and its military may offer some useful lessons for European NATO members. Seoul has a powerful military with a larger armed forces and more firepower and armour than European militaries. It also produces high-quality weapons systems and conducts larger military exercises than NATO, while having a smaller defence budget than European powers.◼
Autonomous underwater vehicles (AUVs) are submersible underwater vehicles controlled by onboard computers. AUV formation is a cooperative control which focuses on controlling multiple AUVs to move in ...a group while executing tasks. In contrast to a single AUV, multi-AUV formation represents higher efficiency and better stability for many applications, such as oil and gas industries, hydrographic surveys, and military missions, etc. To achieve better formation, there are several key factors, including AUV performance, formation control, and communication capability. However, most studies in the field of AUV formation mainly focus on formation control methods. We observe that the research of communication capability and AUV performance of multiple AUV formation is still in an early stage. It is beneficial to researchers to present a comprehensive survey of the state of the art of AUV formation research and development. In this paper, we study AUV, formation control, and underwater acoustic communication capability in detail. We propose a classification framework with three dimensions, including AUV performance, formation control, and communication capability. This framework provides a comprehensive classification method for future AUV formation research. It also can be used to compare different methods and help engineers choose suitable formation methods for various applications. Moreover, our survey discusses formation architecture with communication constraints and we identify some common misconceptions and questionable research for formation control related to communication.
The population living in cities around the world will increase in the next decades. Conventional military forces will deploy more in constrained areas where their high-tech capabilities are not an ...advantage. This research provides an analytical framework for understanding the main challenges of urban warfare for conventional forces. The analysis identifies the military organizational dimension, dual-use technologies as game changers, and the role of civilian population in urban environments as key factors. The conclusions provide some policy recommendations concerning training and communication strategies. The prospects of urban warfare will be defined by a combination of cognitive and kinetic actions.
Martin Bowman's considerable experience as a military historian has spanned over forty years, during which time he has spent hundreds of hours interviewing and corresponding with numerous men and ...women and their relatives, in Britain, America and beyond, resulting in a wealth of material on the war at sea from World War One to the Falklands and the wars on terror.All these narratives have been woven into a highly readable and emotional outpouring of life and death in action in all his titles, as here, in World War Two, where the men of the Fleet Air Arm and the US Navy fighter (operating bomber and torpedo carrying aircraft) describe the compelling, gripping and thought-provoking narrative of the air war in the freezing Atlantic wastes to the waters of the mighty Pacific.
The paper aims to underline the Russian's new role in the Mediterranean region and it is divided into three sections. First, it takes into account the notion of hybrid warfare as it, according to ...NATO and westerner scholars, represents the new military strategy that Moscow devises to achieve its goals. Consequently, the paper studies the current use of the term "hybrid warfare" and then, using a more historical standpoint, it will show how this concept is neither new nor useful to understand current Russian politics toward the Mediterranean region. As a consequence, the paper's second section elaborates on the notion of gray zone warfare that seems to be more appropriate to describe both Russian military operations and its tools.
