### Preparatory Phase  
The phase begins with the inclusion of exercises in the task plan which contain points; see chart below (Figure 2). This content is usually presented in paper form with attached graphics. To increase the effectiveness of the exercise and the creation of the preparatory phase, several planning tools are offered, which allow you to create an adequate plan for the preparation of tactical exercises [3; 6]. In addition to the usual MS Office tools, it is possible to use other tools, for example, PRACTIS software. This programme allows the user to design and modify processes that can also be applied in the field of population protection, crisis management, and IRS. As [PERSON], [PERSON] et al. [16] describe in their article, this is a programme that was developed by a private company, T-Soft, for the needs of the Faculty of Logistics and Crisis Management

Compared with text templates, this programme not only enables the creation of a complete scenario but also allows the addition of time intervals to individual events, their description, and the assignment of the participant's role. The simulation is then validated by its applicability to real-life situations. Common tools do not provide these options; therefore, this programme becomes a market-leading tool that can be used effectively in creating exercises. A unique advantage is a choice between the graphic form or text form at the beginning of the simulation. For use in the IRS, it is possible to simulate exercises according to typical activities for events, such as traffic accidents, fires, a person with a highly contagious disease, or a trapped explosive system, for which an example is created in the attached figures (Figures 3-11). Figure 4: Tabular view. Figure 5: Overview of activities. Figure 3: Scenario creation and graphical display of exercises. Figure 8: Information about shock wave overpressure. Figure 6: Overview of incident models. Figure 7: Initial information about the scope of the event. The user can easily use the tabular view to add exercise participants and assign them their tasks during rescue and clean-up operations. The advantage is a clear system in which it is also possible to shape and re-sequence the processes and activities. In addition to real-time, you can add game time and set a schedule for each event or progress. The game time can be simulated in the programme, and it can be checked whether all the procedures defined in the plan are or have been fulfilled. Figure 10: Programme Pathfinder working environment. Figure 9: TerEx output. Another possibility of use in planning IRS exercises is programme TERrorist EXpert (TerEx). This tool is mainly used to simulate the leakage of hazardous chemicals and explosives. Compared with PRACTIS, it does not offer so many functions, but the advantage is the overlay of geographic information systems, so the simulation can be overlayed directly on a base map. Both programmes then complement each other perfectly, so in the case of exercises focused on chemical substances, traffic accidents with leakage of dangerous substances, or explosions, they are ideal for connecting outputs. An output with a trapped explosive system was also used for the demonstration to show the interconnection of both programmes. The outputs of the simulation include the necessary evacuation, which is shown on the map with the help of a slice. This information can be used to create an evacuation simulation in the programme Pathfinder, which will be mentioned in the next part of the article. The output also includes a graph that determines the pressure of the shock wave. When creating exercises, this data can be used to determine the potential number of injured people around the scene.
