Table of possibilities and a quick comparison of water cannon and multifunction vehicles.
This paper describes the function and development of the requirements for modern and high-quality equipment and accessories and also equipment used by the specialized units of the police force of the ČR with a practical example. This is offered in the form of a draft requirement for a transport means – a multifunctional special vehicle, intended specifically to intervene in situations against demonstrators, extremists, and football hooligans. At the same time, this paper briefly describes the system of collecting information regarding other modern means used by other security forces and also those which are available on the market, which are then (if suitable and also upon experience from abroad) proposed for development and use under the conditions of the Czech Police practices.

In 2016, the Public Order Police Headquarters, Czech Police Presidium (“ŘSPP”), submitted a proposal to the establishment of working teams of police officers from regional police directorates, who are under the coordination of the highest methodical body of the Public Order Police “ŘSPP.” Following this proposal, the Police President Order No. 286/2016 was created. This act established a working team called Blesk (Lightning) , intended for assessment of the current security situation and to evaluate the current needs regarding service tactics for use by the Police of the Czech Republic (hereinafter referred to as the “Police CR”) during actions taken against dangerous crime offenders and to be included in procedures used by intervention units of regional directorates of the Police CR and also the special unit guarding nuclear power plants in the Czech Republic, Temelín and Dukovany. The next Police President Order No. 38/2017 has the same purpose, it was established by the Evoluce (Evolution)  working team and as with the previous order focuses on material security of police officers, but in the case of riot police officers (which means special riot units of police regional directorates (4) and riot units of regional police directorates (12)), taking into account the tendencies of the security situation. Police President's orders allow the coordinator and the team to invite experts from other workplaces of the Police ČR, but also consultants from companies and suppliers to meet and investigate the latest trends in this field of the market. Team workers have the opportunity to be sent to exhibitions and seminars where a particular technology is presented and where they can find out foreign products and compare them with the means which are currently available to the police. No such conceptually formed teams had existed until these teams were formed. Policemen' proposals or requirements were not often listened to or they were strongly misrepresented in other resulting documents. One of the successful projects was dependent primarily on the personal erudition of only one policeman from a special department, who created the future final document regarding the requirements of his work – (training polygon in Zbiroh ) literally in the garage.
2. Research on multifunctional special vehicle
One of the tangible proposals was the future acquisition of a service vehicle primarily intended for use by riot units. According to the Evolution Team´s proposal, this vehicle would be used also by other Police ČR units and it will be possible to be deployed for use as an Integrated Rescue System as well. The vehicles concept draft, as presented by ŘSPP, is the result of the team’s work over several years. During this preparation, the requirements of the leaders and commanders of riot units were addressed, and the possibility of vehicle production in domestic and foreign companies was discussed, including visits to riot units abroad. Upon these findings, modification possibilities of already functioning vehicles were evaluated. However, no vehicle, which would at least meet the majority of workgroup requirements, was found within this phase. Then a professional discussion with several representatives of domestic companies took place, wherein the technical possibilities of the vehicle in terms of construction were addressed. During these, professional discussion possibilities of desired vehicle construction and concerning its future activities were agreed. Several companies within the European Union would be technologically capable of developing and subsequently producing the desired vehicle. From the team's point of view, the best possible way would be through the development and production of a prototype with participation of the work team and then to the subsequent performance testing in operation service. Only then the production of other vehicles would be ordered.
2.1 Usability of new special vehicles
The Police CR have been using a type of special vehicle with water cannon for a long time. This vehicle type had been widely used before 1989 when they served as coercive means to forcibly end demonstrations. After this year, the water cannon vehicle remained in use by the riot police, but with a strong reduction in their numbers. A lack of these vehicles was later manifested in mass demonstrations on the occasion of the meeting of the Monetary Fund and the World Bank in Prague in 2000 when other vehicles of the Czech Army and Fire Brigade had to be called. The vehicles have now been upgraded, but their numbers and technical condition are currently very low and several vehicles are immobile. Public Order Police Headquarters exploits available possibilities to communicate with other EU countries, where they also deal with legal issues of using a water cannon type vehicle as a coercive means. All neighboring states have included these vehicles in their equipment itinerary, but their use varies according to the legal framework. In this respect, the possibility of using a vehicle as a coercion mean under the Police ČR Act is at the same and often a higher level than abroad. On the other hand, we must state that massive demonstrations are taking place in all neighboring countries with significant disturbances to public order, while in our country, eventual demonstrations are less numerous and calmer. However, it is not possible to predict future developments in the Czech Republic based on this situation, especially concerning the immigration crisis and open borders within the Schengen area. It is, therefore, necessary to have such a coercion means available to protect the life and health of intervening police officers, while at the same time allowing termination or at least disrupting such unlawful conduct. Water cannon type vehicles included in the riot police service are a single-purpose vehicle, which its construction is based on the basic fire brigade special vehicle and their parameters and characteristics have not complied with the requirements of the Czech Police for several years. Their deployment is also problematic with regards to their size, maneuverability, and possible documentation of unlawful conduct. As a result of the combination of these elements and characteristics, the vehicles are mainly used for demonstrations and exercises but remain largely unused during safety or security measures. The usability of future vehicles was a key prerequisite in the development of the multifunction vehicle concept. The ŘSPP are fully aware of the duties of proper management and that is why it proposes to change the systemization of these service vehicles when these special vehicles of water cannon type will be replaced by a special multifunction vehicles with a water cannon fitted. The aforementioned amendment shall not affect the wording and interpretation of Act No. 273/2008 Coll., within the Police of the Czech Republic, § 52 let. k) a water cannon, as this is an extension of the name of the official operation transport means. The new concept drafted vehicle envisages that the scope of this act will extend the possibilities of use also for coercive means mentioned under b) tear-forming, electric or other temporarily disabling means, letter f) stopping belt, blocking the road forcibly, stopping the vehicle or preventing the vehicle from escaping and avoiding capture and letter g) forcing out using a vehicle.
In addition to the repressive characteristics of the vehicle, it is also necessary to emphasize its tactical capabilities. The technology that the ŘSPP plans to apply will allow on-line transmission of video (or sound) to the headquarters of a particular situation, documentation of unlawful conduct, making calls or communicating information, and a two-way communication with the headquarters of the situation which is being met or with the control center and intervention units. In addition to this, the vehicle will be able to transmit images from areas affected by a natural disaster, industrial accident, a polluted or otherwise contaminated area or from areas otherwise inaccessible. The ŘSPP dealt with the question of usability concerning the individual units of the Police ČR. Upon the analysis of typical and extraordinary activities performed by the Police ČR, the vehicle is required to have defined characteristics and its technical equipment was then designed. Considering that technological and technical developments are moving forward very quickly, there is a possibility for further expansion within the requirements of the live deployment of the vehicle.
The following table compares existing water cannons and planned multifunction vehicles regarding their deployment possibilities for various activities and usage (Table 1).
|Activity type||Water cannon||Multifunction vehicle|
|Safety measures||City||Yes, on main roads||Yes, even in restricted areas|
|Terrain||With limitations||Yes, almost without limits|
|Emergency||Industrial accident||As with fire brigade support only||Action headquarters support, fire brigade support, possible evacuation|
|Floods||No||Wading up to 120 cm, action headquarters support, fire brigade support, possible evacuation|
|Large fire||As with fire brigade support only||Protection from radiant heat and flames, all-terrain performance capability, action headquarters support, fire brigade support, possible evacuation|
|Mass disaster||As with fire brigade support only||All-terrain performance capability, action headquarters support, fire brigade support, possible evacuation|
|Coercive means||Water cannon||Yes||Yes|
|Acoustic or luminous temporarily disabling mean||No||Yes|
|Blocking the road using the vehicle||Yes||Yes|
|Forcing out using the vehicle||Yes, with limitations||Yes|
|Other activities||Green border surveillance||No||Yes, thermovision, night vision, image transmission|
|Soft targets||Partially||Thermovision, night vision, camera recording, calls, mobile roadblock, image transmission to headquarters|
|Large sport or other events||No, only for road spraying at hot days||Action headquarters support, image record and transmission, calls, drinking water in hot days, road spraying in hot days|
|AMOK||No||Partially, image and sound transmission to headquarters, calls, logistics background for action squads|
|Search actions||No||Logistics background for units, drinking water, lighting, electric circuits, camera surveillance or thermovision|
From the table above, it is clear that the vehicle could be used for numerous operational activities. The reason why the work team and the ŘSPP prefer a multifunction vehicle is based on two factors. The possibility of universal and frequent deployment and saving money, compared to the purchase of more single-purpose vehicles. The actual deployment (in the case of a security measure) is another decisive element that would require at least three separate vehicles with their crew, which then deprive the maneuvering space of intervention units and three crews are therefore necessary, who could have been deployed elsewhere and otherwise. It should be noted that the idea of a universal vehicle, which has been developed by the ŘSPP since 2015, instigated by discussions held by a team of professionals, is going in the right direction. Today we can already see one fire-fighting special vehicle produced by Hlučín Fire Brigade; however, it lacks the basic and essential characteristics of this police multifunction vehicle.
Technical specification (serving just as a base for proposal and numerous negotiations of the team).

2.3 Comments to vehicle equipment
The team has designed the vehicle so that the crew can perform the tasks asked of the headquarters while responding with security measures and mainly to support the intervening units. Its construction is designed to be robust because heavy equipment is currently missing within the equipment of the Czech Police and it is necessary to cooperate with Fire Brigade units, which is not always convenient or possible taking into account time requirements. The possibility of using LRAD devices as a safety measure should be highlighted. This equipment is already in use by the police and its deployment greatly facilitates and at the same time improves the performance regarding challenges and the transmission of information. It should also be mentioned that the device can be used as a coercive means with a temporary disabling effect. A camera system allowing documentation of unlawful conduct, which allows the transmission of up-to-date information of the staff during these measures direct from the place of the intervention and thus providing surveillance of the situation to commanders of the intervening units is another element. The vehicle itself can safely move directly on the site of the intervention without any risk of its significant damage (unlike current camera cars). At the same time, the commander shall be a part of the vehicle, who may analyze on-the-spot the evolution of measures concerning unlawful conduct and provide the headquarters or the intervening units with this information. Lastly, but not least, is the use of a water cannon (monitor) with continuously variable pressure and shape of the water jet. The monitor itself will be equipped with a rangefinder and camera, so the operator will be able to control the monitor using controls from the cab, but at the same time, he will precisely see where the water stream exactly hits. Another advantage is that the use of the water jet against a specific perpetrator can be automatically documented. The whole device will allow the tear-forming agent to be mixed into the water stream and sprayed over a large area within a second or a short impulse to cover a small space. Marker paint admixture is less aggressive, it serves as a clear identifier for intervening police officers that an individual is likely to have committed an offence and can be apprehended to explain themselves after the cessation of such a measure and compare camera images within a particular proceeding. Especially in conditions of reduced visibility, a so-called light curtain can be used, which may serve as a coercive means (painful stimulus when looking into the light), but at the same time allows for good illumination of the targeted site and its main purpose is to hide the activities of units behind the vehicle.
The general advantage of this vehicle is that it is not necessary to have the monitor in a standby position during normal measures, but that the vehicle acts only as a camera car. If the vehicle is used outside this measure, it will allow the units to create a background with utilities (light, electricity, water, transport of other materials, transport, and a heavy trailer) even to places where other police vehicles can get into problems or not be able to reach at all. The possibility to remove obstacles from the road by either pushing or by use a winch is another important feature. If necessary, the vehicle can travel through water with a depth of approx. 120 cm, even with an unpaved watercourse bottom.
Enumerating all deployment possibilities is very difficult because it will depend on the ability of commanders to utilize the maximum potential of this vehicle. It is clear that this vehicle meets the requirements of modern trends and concepts of security forces within the EU and the world.
This paper presents the function and development of requirements for modern and high-quality equipment and for equipment of special units of Police ČR with a practical example, which comes in the form of a draft requirement for a means of transport – a multifunctional special vehicle, intended to intervene against demonstrators, extremists, and football hooligans. No such vehicle exists now in the Czech Republic, of which its development and proposal for future possibilities of its use which has been created by a team of police officers who perform daily service in the streets within security measures, so it would be quite unique in its purchase and production, but the authors do not have the ambition to describe in this paper the details of the future steps of the vehicles development or its purchase. The authors describe the means and idea of creating working teams, consisting of ordinary police officers, who thanks to the work of such a team, can from their own experience suggest its optimal means, which, in their opinion, is missing in practice and would be useful. At the same time, this paper briefly describes the system of collecting information on modern means used by other security forces and on the market, which is then (if suitable and also upon experience from abroad) can be proposed for development and use under the conditions of the Czech Police practice.
