The Problems of Prevention of Socially Undesirable Behaviour

Nonreviewed - Review

Ing. Michael Hrbata

Vojenské rozhledy / Czech Military Review Nr. 1/2012, Vol. XXI. (LIII.): 42-55

Armed forces, civilian employees, are extremely exposed to unwanted effects of socially undesirable behaviour, as they live and meet their assignments under difficult conditions, e.g. in mission abroad, separated from their relatives, spouses, wives. The best deterrence against socially undesirable behaviour is its prevention. Legally this problem is defined in the Defence Minister Order No 53/2010, The Prevention of Socially Undesirable Behaviour. According to the author M. Hrbata, Deputy Defence Minister for Personnel, we must deal with this problem in a multidisciplinary manner, in the frame of effective organizational structure, run by competent commanders, chiefs, directors, with natural authority.

Vojenské rozhledy / Czech Military Review Nr. 1/2012, Vol. XXI. (LIII.): 79-88 | DOI: 10.3849/2336-2995.21.2012.01.079-088

The essay deals with the concept of total force policy concept and its implementation. Some facts related to the history, implementation and development of this construct are presented in context of the Czech White Paper on Defence released in 2011. In order to improve capabilities of the national armed forces system, and as well as to diminish risks related to lack of human and financial sources in face of impeding population ageing, the author suggests a return to total force concept in the Czech Republic. He admits that the experiences with this policy before 1990 will be inoperative, as there is no chance of reintroducing of compulsory military service or the re-establishing of such paramilitary institutions such as e.g. the SVAZARM used to be.

The Current State and Trends in Space Security

Ing. Vladimír Šilhan, CSc., MSc.

Vojenské rozhledy / Czech Military Review Nr. 1/2012, Vol. XXI. (LIII.): 132-147 | DOI: 10.3849/2336-2995.21.2012.01.132-147

Space applications and use of satellite data became an important tool for production and development of many companies and institutions, as well as indispensable part of our daily lives, when using e.g. satellite navigation or TV broadcasting. Proper functioning of those services, however, requires the security of space assets at the orbits, their ground stations and the transmition links. The basic threat for space assets is the growing number of debris at the orbits. Space Situation Awareness has a growing importance and sharing information among all main space actors becomes a pre-requisite. Efforts to agree on common guidelines to mitigate possible risks related to outer space activities are made both within the UN and the EU as well as among all space agencies.

Vojenské rozhledy / Czech Military Review Nr. 3/2011, Vol. XX. (LII.): 146-161

The article deals with the problems of current "military engineering" in Czech Army, which arose during drawing up the "Doctrine for land forces operations". The content of this article consists mainly of three parts. The first one has to characterize some doctrine development aspects from the engineer's contributor point of view. Secondly, to adduce requirements for the content of a doctrine which are consequent to NATO main military engineering documents, e.g. MC 0560, AJP-3-12(A) and ATP-52(B). Thirdly, this level has to evoke resourceful discussions on topical military engineering within military community and to contribute to the mutual opinion consensus achievement.

Roughly since the 80's of the last century, in worldwide scope, new accelerated processes and heavy globalization tendencies have been manifested. Such phenomena forced classical economists and financial managers to change their thinking. Conventional methods of management have been replaced by new, modern approaches towards the issue. One of most modern methods of the political economy of defence spending around the world is the famous outsourcing and its variants fitted for the army.

The authoress deals with the question of financial resources the AČR will be able to spend on issues tied with state defence, i. e. for the needs and demands of defence department. In fact, its sources represent the main base for the support of the Czech armed forces. To predict the volume of financial means allocated for the forces is problematical, questionable. We must be prepared for further budget cuts, we must prepare B-scenario for the worst situation.

General View by Doc. Dr. Jiří Nedbal, CSc. When we prepare activities/exercises of military units, we can make use of theory of asymetric information that offers wide scope of decision variants. We can use PERT method which is not very difficult to understand. This can help us to disclose hidden reserves, sources, problems. We also could take over experience from other armies. It is important now, when percentage allocated from defence budged is still shrinking.

First, we must define applied terms, such as state of danger, emergency, state of state emergency, state of war, sovereignty, democratic principles. Our national reserve consists of compulsory reserves and active reserves. The author enumerates with the use of vast tablets and charts their numbers, together with numbers of military occupational specialities, and explains terms extraordinary service in time of eminent danger, during military exercises, in time of proclaimed state of emergency. He also cites numbers available for conscription (draft). Last but not least, he quotes arguments and conditions under which a reserve soldier can refuse call up order. Defence Act specifies all conditions of national military service, which also includes calling up women, except for those who are e.g. pregnant or are raising children up to age of 15 years.

NSIP-NATO Security and Investment Programme presents an outstanding field of cooperation among Alliance nations and are the fundamental pillar for planning their common defence. The programme serves for securing necessary sources for investments in building, renovation and establishing air and navy bases, strategic depots, core radar systems, and the like. It also supports individual national commands. The article shortly summarizes the history of NSIP, cites examples of its implementation and formulates proposals how to better utilize common sources of this programme. The Czech Republic belongs among states that still enjoy benefits from common funds, particularly in the connection with the building backbone NATO airports. The genuine contributors are Canada, the U.S., and Belgium; at the head of benefit states are Turkey, Greece, and Portugal. It is recommended for Czech representatives at the HQ Allied Command Transformation to increase number of them in decisionmaking staff elements to prevent administrative complications with allocation of approved investments.

Vojenské rozhledy / Czech Military Review Nr. 1/2007, Vol. XVI. (XLVIII.): 153-159

The first part of the article defines notions of the competence, the power, and the authority. Next part of the article deals with the assertion of the power and authority. Those terms are not the same. Whereas the power is universal, the authority of a commander is performed only within the Army of the Czech Republic (ACR), it does not go beyond. The authority presents the "right" or "duty"; the power is the capacity to implement authority, to fulfil intentions. Business, labour, educational, governmental and military systems depend on a hierarchy to carry out specialized tasks. Therefore the authorities are tied with individual levels of mentioned hierarchies. In the professional forces the formal authority is not enough. Professional warrior is an expert that can't be managed in ways the soldiers used to be, in the former conscript army. It is necessary for the commander to exercise natural authority, based upon knowledge, skills, all-round proficiency. Formal aspects of his authority are only secondary.

Theory of Defence, or Security Science? (Keynotes for Scientific and Research Activities in the field of State Defence and Security)

Nonreviewed - Research

Doc. PhDr. Jan Eichler, CSc.

Vojenské rozhledy / Czech Military Review Nr. 4/2006, Vol. XV. (XLVII.): 19-26

In the early 21st century defence research can be discussed in two ways: we can stay either within existing discipline "theory of state defence", or we can set up new academic specialization concentrating more on the notion "security" and its individual aspects, including their inner ties. In the former case, there are spheres in which civil and military experts can complement each other, whereas other spheres of studies ought to stay exclusively in the domain of military experts. Mutual cooperation between civilian and military experts can be concentrated on systematic studies of security threats, predictions of potential conflicts, analyses of security cooperation between the Czech Republic and NATO, the EU and the OSCE, economy support of state defence. On the contrary, military specialist ought to focus on e.g. major regional conflicts, low intensity conflicts, military operations other than war. As the term "security science" is not used in NATO nations, the author suggests, it would be more useful to preserve academic discipline "defence theory" to make full use of military experts.

Intelligence in Asymmetric Operation of US Army

Vojenské rozhledy / Czech Military Review Nr. 4/2006, Vol. XV. (XLVII.): 81-86

In today's conflicts, such as the Global War on Terrorism in Iraq and Afghanistan, the threat is more difficult to define; in fact, there are often multiple threats working against our forces concurrently. Our army lacks first-hand information from current battlefields, so that the author must make use of mediated experiences. The paper is therefore based upon articles from foreign military magazines, namely Intelligence Synchronization on a Nonlinear Battlefield (Military Intelligence Professional Bulletin 4/2004) and Intelligence in Peacekeeping Operation (International Journal of Intelligence and Counterintelligence 1/1997). It is not a mere translation or compilation, but ingenious summing up of discussed ideas. In this study, the author thinks over intelligence synchronization and proposes a new way of looking at it. Methodology heads from priority intelligence requirements towards specific information requirements, via indicators, and so on. The purpose of intelligence synchronization is to focus efforts to build, refine, or clarify the commander's understanding of the battlefield and the threat.

Vojenské rozhledy / Czech Military Review Nr. 3/2006, Vol. XV. (XLVII.): 71-86

Economy of production, economies to scale, in civilian sector are quite different than economy pattern in defence sphere, as specifying the allocation of sources for the Army of the Czech Republic is not based on exact calculation of costing, payments as we could not observe the substantial terms of comparable partial and overall expenses. At present, we are not fully able to compare defence outputs, nor effecitivity of spent sources.

Doc. Ing. Oldřich Horák, CSc.

Vojenské rozhledy / Czech Military Review Nr. 4/2010, Vol. XIX. (LI.): 49-54

This paper deals with aspects of intelligence analysis that very often influence the quality of intelligence information utilized by end users. Such analysis requires not only analytical thinking, but also specific experiences of all personnel exploiting collected information. The same body of information may result in multiple analytic products, with different security classifications, time scales, and level of detail. The result of this process is an analytical product - evaluation without any idle speculation and pseudo prophecy. Evaluation and interpretation must describe up-to-date conditions and demonstrate the clusters of future images with alternative developments. Reasonable evaluation reduces uncertainty and makes user's decision easier. At the end the author concentrates on rules of analytical team control and management.

Vojenské rozhledy / Czech Military Review Nr. 4/2010, Vol. XIX. (LI.): 121-131

Since 1990, members of ACR forces have taken part in 29 foreign missions, some of them continue even today. A total of 24,171 soldiers have participated. The authors with regret state that in spite of the fact of 20 years of foreign missions, no military manual dealing with methodology of building military bases was approved. This article tries to bridge this gap. It depicts fundamental components of military base and enumerates six principal wholes of such base, further 23 basic types of elementary sections. The article was written within the limits of defence research project "Technology Support to Projection, Construction, Maintenance and Dismatling ACR Bases in Mission Abroad, with the Use of REACH-BACK Concept", which was elaborated at the Department of Engineer Technologies, in cooperation with Department of Combat Support Management, Defence University, Brno.

Opinions, controversy

Pplk. Ing. Bohuslav Pernica, Ph.D.

Vojenské rozhledy / Czech Military Review Nr. 4/2009, Vol. XVIII. (L.): 114-123

The important part of the forces transformation deals with the problem reducing in numbers of officers, namely field officers and general corps in the Czechoslovak Armed Forces and lately the Army of the Czech Republic. The main cause of this reduction was new concept of military career, as before the transformation it used to be a lifelong profession. The downsizing started in 1990 and it ought to have been finished by the end of the first period of the Czech Armed Forces Reform, as of 2008/12/31/, but it appears that downsizing is endless. The author quotes figures concerning numbers of officers; several rank charts and tablets with corresponding NATO and Czech grades respectively are used to demonstrate veracity of his statements. According to Lt.Col. Pernica, the downsizing is going to continue but no one knows how many officers for the all-volunteer Czech armed forces will be enough.

Social Engineering in Czech Armed Forces behind the Risk Edge: Results of 15 Years of Experiments with the Creation and Implementation of Career Rules

Opinions, controversy

Pplk. Ing. Bohuslav Pernica, Ph.D.

Vojenské rozhledy / Czech Military Review Nr. 1/2009, Vol. XVIII. (L.): 76-80

This highly critical article, the author opens with a statement that 15 years of changes, implementation of rules, professional career advances do not fulfil expectations. The problem is more serious as the armed forces do not compete effectively in labour marked, with the implication of wasting public money (from defence budget). The whole situation is demonstrated on pay and career stratification of career officers and soldiers. Among others, in comparison with civil sector, military pays have low level of competitiveness. The article is supported by several graphs and tables.

Effective operations of institutions within public sector presuppose obtain necessary knowledge how those institutions operate in the scope of their responsibility. Collected data could be used for making use in higher levels of command and control. The data might be acquired via the audit of activities of examined institution. This study tries to outline main basic steps how to accomplish the audit of institutional activities with the stress on a level of administration and management. By definition, audit is inspection and verification of the accuracy of financial records and statements. Internal audits are conducted by a company's own personnel to uncover bookkeeping errors and also to check costeffectiveness of labour. An external audit is used to give the public a true statement of an institution's financial position. The auditors inspect real estate, buildings, and other assets to see if their value is overstated.

Vojenské rozhledy / Czech Military Review Nr. 1/2009, Vol. XVIII. (L.): 100-109

Evaluating offers of contestants for public contracts belong to key and critical moments of public tenders and the whole acquisition process at all. Variety and comprehensibility of numerical and rating methods shouldn't prevent applicants from understanding conditions and terms of contract/agreement. The transparency principle of evaluating is only slowly pushing forward in our legal system. We move from mere subjectivistic and unverifiable impressions to the unbiased comparing of best offers, together with the requirement of transparency, as a part of the process of comparing, ranking, and assessing offers, by the use of specific qualitative or quantitative factors, such as prices, feasibility, collateral risks, time plan or other conditions. The final step is called amalgamation, when we merge individual classifications in one complex appraisal.

The Centre of Gravity is a Cause, "Matter", not the People

Informational pages

Vojenské rozhledy / Czech Military Review Nr. 2/2008, Vol. XVII. (XLIX.): 125-128

As the military's current fight against terrorists and insurgents does not follow the templates of the past, it requires innovative, adaptive thinking. This article summarises the main ideas of the essay "We the People are not the Center of Gravity in an Insurgency" by Maj. Mark P. Krieger, published in Military Review No. 4, 2007. A COG could be characterized as a source of power from which a military force derives its freedom of action, physical strength, will to act. The definition is important namely when military planners try to identify enemy COGs. There is a single COG at the operational level; the tactical level of war has decisive points. COGs organize and direct critical capabilities, physical or psychological. An insurgency's case is its strategic COG, its organization is operational COG, and the people are a decisive point at the tactical level. The population is important in an insurgency, because the people are a tangible to target, but it is not a COG. Attacking an insurgency?s organization will weaken the strategic COG that becomes vulnerable to attack and destruction.

In NATO, here are many common items in welfare benefits, and there are different ones. Authoress depicts military social welfare in the CR, Slovakia, Germany, France, Poland, Hungary. The final part of this article compares systems of military benefits of mentioned countries. The authoress enumerates various conditions to be fulfilled, so that soldiers were entitled for welfare or retirement benefits. In nearly all countries, veteran?s pensions are regarded as the substitute for deferred, postponed pay. Retirement pays have its source in the last soldier?s salary. In the Czech Republic, retirement pays are based upon serviceman?s average best income in a calendar year, before he leaves the army, the time he served in the army, and its real income. Czech veteran?s social security scheme is separated from general (civil) social security system, as there some special military benefits that can?t be taken over by civil authorities.

The authors depict the development of outsourcing methods in US armed forces, its origins, and sources. Collected data are accompanied by experiences from British and German armies. The American Office of Management and Budget (OMB) issued in 1966 Circular No A-76 (lately several times revisited) to define procedures how to set rules which commercial activities are to be done within the frame of armed forces or in private sector. Backed by a number of literatures, magazines and newspapers (Air Force Journal of Logistics, Air Force Magazine, Armed Forces Journal, Defense Nationale, Washington Technology, Wehrtechnik, etc.) authors analyse several outsourcing processes. They present both positive and negative results, including open or hidden problems of A-76 policy (e.g. business process outsourcing). For the Army of the CR they recommend to overcome above mentioned problems by creating the corrective authority, similar to the British PPPU (PublicPrivate Partnership Unit).
