This article examines autonomous reconnaissance in a complex urban environment using unmanned aerial vehicles (UAVs). Environments with many buildings and other types of obstacles and/or an uneven terrain are harder to be explored as occlusion of objects of interest may often occur. First, in this article, the problem of autonomous reconnaissance in a complex urban environment via a swarm of UAVs is formulated. Then, the algorithm based on the metaheuristic approach is proposed for a solution. This solution lies in deploying a number of waypoints in the area of interest to be explored, from which the monitoring is performed, and planning the routes for available UAVs among these waypoints so that the monitored area is as large as possible and the operation as short as possible. In the last part of this article, two types of main experiments based on computer simulations are designed to verify the proposed algorithms. The first type focuses on comparing the results achieved on the benchmark instances with the optimal solutions. The second one presents and discusses the results obtained from a number of scenarios, which are based on typical reconnaissance operations in real environments.

The Czech Republic, as a member of international organizations (NATO, EU, UNO), with respect to current global security neighborhood, employs the units of the army both at its own state territory and outside the Czech Republic, in multinational forces operations. The article focuses on Linear and Angular issues in perspective Artillery Fire Control System called PVNPG-14M. The issue of automated command, control, and information systems is of high importance in the solving of asymmetrical operations tasks today and in the upcoming future. The authors define appropriate Linear and Angular variables for common use by soldiers of the Army of the Czech Republic. Final assessment of the particular issues is determined by analysis. The The article contains theoretical justification and establishes a practical rule for use.

This paper is focused on suggestions and recommendations for suitable guidelines for fulfilling of The sketch of topographical-geodetic connection. This paper contains table of contents and method of “The sketch of topographical-geodetic connection” fulfilling. The paper presents problems of current Artillery communication and information system and suggests requirements of the future system.

Artillery units in the NATO armies have to be able to perform firing data calculations using standardized meteorological messages METB3 for manual calculations and METCM for computerized calculations. Artillery of some armies (especially of the former Warsaw pact) cannot process these messages because of some their weapon systems, firing tables and implemented tabular atmosphere model. They are still dependent on non-standardized meteorological message METEO11. This paper brings the solution for the Czech Army artillery of the introduced problem in the artillery meteorological support. Solving the problem lies in the ability to perform METB3 meteorological messages conversions into the METEO11 format. Authors have defined the original mathematical model of conversions, which they have used for the development of the new software. In the end of the paper, there is a short analysis of the conversion accuracy.

Artillery units assigned to multinational task forces cannot carry out effective fire without previous fire adjustment, creation of fictive targets and conduction of a complex meteorological measurement by its own units. Incompatibility of Czech artillery and some other states with NATO armies is caused by use of different model of tabular atmosphere, non-standard firing tables and format of the METEO11 meteorological message. Following article deals with this long-term incompatibility by use of new application support made by authors. In development of this program it was necessary to define new procedure of partial data calculation in meteorological message, which is generated on basis of measured meteorological data abstract from the MARWIN MW32 sounding system used in NATO armies.

This paper is focused on perspective method for determination fire for effect in tactical and technical control of artillery units in the perspective of automated artillery fire support control system and deals with a proposed method of adjust fire. This method is designed for artillery of these armies that are using the field artillery. Artillery units of the Army of the Czech Republic, reflecting the current global security neighbourhood, can be used outside the Czech Republic. The paper presents problems in the process of adjust fire method, from results arising from creating a fictional auxiliary target; by using an adjustment gun; Abridged preparation and Simplified preparation. The paper compares these methods in terms of time, accuracy (probable error in target distance and target fire direction) and frequency of use in peace and war.

As far as the projectile/armour interaction is concerned, it can be generally stated that the interaction triggers degradation processes, and subsequently leads to a limit state in the material. The nature of the armour plate damage is directly related to the type of ammunition used and indirectly to the operating conditions (the shooter’s capability, the technical condition of the weapon, etc.). The paper examines limit conditions (critical temperature), under which ballistic resistance, which is measured based on determined mean velocity V₅₀, decreases. Military vehicles deployed in peace missions abroad operate under various climatic conditions characterised by significant temperature variations in the course of day. When superposing the ambient temperature influence and the ammunition effect, the projectile penetration through the material and unexpected expenditures relating to the restoration of the damaged material original properties can be assumed. In addition to the efficient use of public financial means, foreign operation logistic support planning must take possible damage to the military vehicles, resulting from enemy’s combat activities, into consideration. On the basis of the determined mean velocity within the temperature range -80 °C to 100 °C, the correlation of selected material characteristics was studied. In order to determine the share of the test temperature in the material degradation states, the experiment was supplemented with a fractographic analysis and transmission electron microscopy.
