Abstract
<jats:p>The increasingly dynamic and complex nature of service in law enforcement agencies, particularly the armed forces and internal affairs agencies, places heightened demands on the professional training of personnel, including their physical and psychological fitness. The effectiveness of soldiers and internal affairs officers in fulfilling their assigned tasks is largely determined by their ability to confidently operate under conditions of ever-increasing cognitive load, which must be countered by the strength of their cognitive ability to demonstrate a sustainable state of vigilance adequate to the challenges of the time and demands of the day. In this regard, the quality of psychological work, which enables law enforcement officers to effectively manage typical sources of cognitive load at the tactical level, is undoubtedly noteworthy. These include complex human-machine interfaces, equipment with inconvenient control procedures, the particular sophistication of criminal intent, and the persistent desire to implement these plans. Under these conditions, strengthening the psychological foundations of vigilance is essential to ensure precise maneuverability and the appropriateness of decisions by military personnel and law enforcement officers. Particular attention should be paid to factors negatively impacting the cognitive abilities and, consequently, the vigilance of military and law enforcement personnel, as well as the nature of stress factors associated with the performance of assigned tasks (time pressure, uncomfortable and dangerous service conditions, the complexity of incoming information, etc.). These circumstances indicate the need to rethink and subsequently improve the level of training of military personnel and law enforcement officers for performing tasks in the most challenging conditions, as well as to deploy specific tools to measure human vigilance and equip military and law enforcement personnel with appropriate recommendations for considering the psychology of vigilance in the context of increasing cognitive load.</jats:p>
