The paper treats logistic operation and its logistic support Certain new moments are introduced into the classical approach to logistic operations Besides the fundamental characteristics of logistic operations, the paper gives logistic support functions and tasks as well as its principles and recommendations for rising its quality. The importance of planning and managing logistic support of logistic operations is stressed, with the accent on tendencies in its improvement. Logistic systems and operations are followed through their life cycles while logistic support is treated from different aspects. Hierarchical decomposition and data classification are applied. Successivity in problem solving is pointed out as well as main points and priorities.

Dislocation of material supplies (MS) has been discussed as well as the functioning of logistic support system elements at different locations. After the definition, organization and technology of MS dislocation, the paper gives its planning and cases where optimization of different loads and transportation means is required. The method of dimensioning technological elements meeting the technological requirements during dislocation has been presented as well.

Besides explosives and propulsive devices, electric energy represents the third crucial element of battle energy. Calculation and understanding of electric energy balance of units imply determination of needs for electric energy (sources, chargers, transformers, converters), enable optimal solutions by the help of available equipment and in commanding they provide making timely and high-quality decisions thus representing an important factor of unit combat readiness. Furthermore, knowledge of electric energy balance provides unit autonomy, which is very important in planning and realization of particular missions and activities. This paper presents a mathematical model for electric energy balance determination for any type of units, all circumstances and missions they may be involved in. The model is applicable with or without use of computers, thus providing its wide and all level-application.

It is very important to provide continuous air surveillance in to realize modern operations on the operational-strategic level and tactical, as well. It is well known that active radar systems, on which air surveillance is based in our country, are very vulnerable in war times and susceptible to the electronic counter and combat attacks of the enemy, what is shown practically in 1999 war. Air surveillance by passive multi-sensor systems is a possible alternative to the air surveillance by the active radar systems. Subjects of our wider research are technical solutions of integrated multi-sensor systems for passive air surveillance which consists of the following subsystems: a subsystem for the air communication intelligence within the frequency range 20-3000 MHz based on intercept/direction finding principle, a subsystem for the air surveillance based on the acoustic intelligence, a subsystem for the air surveillance based on the station for the visual intelligence, a subsystem for air surveillance based on thermo-vision and television principle. General principles of air surveillance are presented, and the concepts of the subsystems for the air communication intelligence and acoustic intelligence are proposed in this paper.

Starting from the elaboration of the basic principles of communication intelligence, a problem of communication intelligence in HF range 1,6-30 MHz on the operational-strategic level is analyzed in detail. A concept of the wide-band multifunctional direction finder with integrated intercept and direction finding functions is presented. The direction finder should provide complete surveillance of the HF range and interception with direction finding of all active signals in given frequency range which are not shorter than 10 ms. The direction finder is the key element of the future automated radio reconnaissance system for the HF range, that should provide a complete insight of the signal activities in the HF range, which the existing communication intelligence system does not provide. The subject matter of this paper is based on the analysis of experiences and current trends in this field in the world, on experiences gained in VTI in previous research and development projects, especially in development and testing of the prototype of the direction finder fot the VHF/UHF frequency range.

The application possibility of ad hoc mobile communication network for connecting sensor systems, as node sources of information and as node elements of communication network's infrastructure, in command information system is presented in this paper. The next step in wireless communication evolution is ad hoc networks, which appear in the form of groups of mobile computers, mobile phone devices, personal digital assistants and in the form of a network of autonomy electronically sensors devices. The basic characteristic of every ad hoc network is establishing communication between network nodes without fixed network infrastructure, established in advance. Instead of fix network nodes and basic stations, that are typical of available wireless networks infrastructure, network of nodes of sophisticated sensors devices (stations) became most important for communication. Possibility of eliminating the need for fixed communication infrastructure in security systems and systems for territory control, is very important in military, especially for the preparation and leading of modern operations. Some of the examples for practical application of ad hoc networks are: air surveillance system based on visual surveillance and acoustic-metric stations, sensor systems for protection of objects and space and collection of relevant information data.

Fast progress in commercial communications systems development has made possibilities to fulfill communications needs in military organizations especially during the periods of peace. A reconnaissance system, based on specific military technology such as passive radar systems and acoustic sensors, available in commercial market, represents a possible realization of a simple and highly efficient system. Necessary communication with a higher command, also as actions that are made based on gathered information, could de supported through use of commercial communications systems employing adaptive modulation processes, direct sequence and freqyency hopping spread spectrum communications and code division multiple access. In this way organized systems completely fulfill communication needs of the Army of Serbia and Montenegro during peacetime, but the applicability of such systems expends partially or fully on cases of limited military interventions antiterrorist actions and nature disasters.
