Aim:
The aim of the study is to determine the effectiveness of psychological preparation methods for future specialists in the security and defense sector in extreme conditions, specifically evaluating emotional and cognitive reactions to stress factors, and exploring the potential of human resources in these conditions to enhance the effectiveness of professional activities

Material and methods:
The study involved cadets from Dnipro State University of Internal Affairs, divided into two groups: Group 1 (control, n=120, mean age 18.86±1.25) received standard training, while Group 2 (experimental, n=120, mean age 18.73±1.19) underwent 10 months of specialized training for extreme conditions

Results:
A special training program with crisis models, such as "Technogenic disaster in a combat zone," led to a statistically significant difference between the control and experimental groups (p<0.05) after using the Stress Resistance Scale. The Cattell test (16 RF) showed that the experimental group had a higher emotional stability score compared to the control group. Emotional stability test results revealed lower anxiety levels in the experimental group (p<0.01). A framework for "Human Potential Development through Assessment and Adaptation" was developed, focusing on emotional and cognitive reactions. Practical recommendations were provided to improve training programs and enhance psychological resilience for future specialists in the security and defense sector.

Conclusions:
Improving special training programs for future specialists in the security and defense sector should integrate physical, cognitive, and psychological aspects, considering individual traits. A systemic approach, including psychological preparation and stress management skills, will enhance psychological resilience, essential for success in extreme conditions
