Revolution in Military affairs is a process that major change and discontinuities in military affairs take place. They are brought about by changes in military related technologies, concept of operation, methods of organization, and/or resources available, and are frequently associated with broader political, social, economic, and scientific revolutions. The modern period in general and the past two centuries in particular have witnessed the greatest rate of change.A review on past changes shows the complexity and differential of issue, that this article refers to its 3 distinct models and RMA dynamic factors and Persian golf war futures in this background.Also progress of RMA in some countries such as Pakistan be discussed and pay to the new dimension of war such as net centric warfare, air-space warfare and challenges relevant to RMA and refers to guidelines for developing countries like Pakistan, that include; development of existence systems, autonomy, simultaneous intend in going toward RMA and importance and role of privet sector.For example: refer to changes in U.S. army and India army then after discussion, concludes in choices in front of developing countries. This paper is translation of 2008 journal AWC PAF that offers to readers and all those interested with a little expense and expand of issue.

In resent decays, depends on global and regional evolution Indian Ocean have been center of consideration of region and foreign country as the most important waterway between five oceans and each of them adopted some actions for presence and domination in area perspective. Attention to process of global change and limitation in energy resources, anticipation is more attending by effective sea power countries’ during 21 century. Indian Ocean is the most important waterway for IR of Iran as lines of communication and depth of sea defense. Effective attendance of IRI navy on this ocean will provide security of our lines of communication and move out battlefield area from Persian Gulf and Oman Sea at critical date and in peace time will defense of national interest on international water. Continues and effectiveness of this presence needs some requirement in national level.

During the history, war has been related with development of technology directly. By the erly of 21th century, the century that identifies by “communication and information era”, development of communication and information technologies has changed the nature of war. In this circomestanses appearance of new methods against air threat, appearance and role of the new radars with advanced technology is undeniable. Today as long range target detectors, over the horizon radars in HF band with electromagnetic wave dispersion ability to space and use of wave reflection character of ionosphere in compare with line of sight radars have regarded for applying by developed countries.This essay had tried to research on reason of application and effective factors in over the horizon HF radars working. The reason of apply, comparison of target detection and feature of these radars with ordinary line of sight one will explain completely. Therefore we will introduce main factors of O.T.H radar’s structure (receiver, transmitter, antenna and data processor) and finally after proposal management of radar, ionosphere layers and loss of energy will get logical conclusion.

Military History and the Art of War military are basic courses of prestigious universities of the world and military thought are the basis of military behaviors and functions which visualizes in military identity ,ideology and military philosophy, military theory, military doctrine, military power and authority. Considering that the major military affairs, defense and defensive strategy on Iran over the history has been the result of thoughts, insights and efforts of scholars, rulers, politicians and military commanders for centuries and the question “ how can a country be protected against threats?” has been the main question here. Therefore, studying the military thought during Iran varying history is of a great significance and necessity. Therefore this paper aimed to explain different ideas and theories during the history of Iran's military and also expanding and spreading military education, military ideas and theories of different periods and finally, thinking, pondering and applying it. So this type of research is practical from targeting point of view and from way of collecting data is descriptive, and library sources are used for gathering information.Studying remained texts of a proud history of Iran, it is realized that the most important Iranians defensive excellence is having different ideas and techniques of war and use of this military thoughts in battles and prowess of various tribes of Iranian peoples against their enemies which historically have been aimed to establish values. So getting more familiar with various military ideas and theories and the system dominated on war and defense field has been important during the Iran’s history has played an important role in role in increasing the experience, knowledge, consciousness, awakening and insight of every armed force personnel against the hegemonic powers and aggressors.

Naval force is centeric material and centric proficiency force. Strategic naval force needs special material. Nowadays naval operation is based on submarine operation. Thereby naval operation planners and submarine desighners are seeking methods which enemy can not detect by acoustic sensors. This dual process always exsists. Lidar is a technology which can detect underwater objects whithout use of acoustic waves. Lidar and radar works similar and but they differ in applied waves length. Radar uses short waves length, but the lidar applies light waves length. The lidar can not measure in all weather conditions, whereas the radar does. This technology is currently being used for high-resolution topographic mapping by mounting a lidar sensor, integrated with global positioning system and inertial measurement unit and in oceangraphy researchers such as, determining water depth, signifying water pollutants and also underwater photography. Military applications of this technology involve preparation of topography and hydrography charts. Lidar is the only equipment which can collect hydrography and topography information together. We also use it for detecting enemy submarines in antisubmarine operation. Another use of the lidar is atmospheric research to measure ozone layer, vapour and pollutions in atmosphere. Lidar data also are being used in wood, urban development and oil exploration.

Employment of advanced communication technology and utilization of rapid and immediate informational systems for the purpose of providing communication between the main elements of the battlefield (command and control centers, sensors and intelligence systems, operational forces and communication and combat equipments) are some of the main causes of victory at war and supremacy over the enemy at present wars which are known as information warfare.Today’s warfare system has the most mobility and dispersion towards enemy conditions. The components of the system are continuously moving, transferring, reorganizing, appearing and disappearing. Therefore, the enemy is always trying to disrupt and destroy them by physical force or electronic and communicative systems. The C4I network structure connects these elements to form a vast information network in different operational levels and then, after collecting information from the whole battlefield and processing it, publishes it for decision-making. This type of network should have some characteristic features. In such conditions, the C4I network, which contains hundreds of great communicational networks and thousands of military equipments and devices, should have a structure that can support all parts of the network in a reliable manner.
