This article analyzes the impact of length of service on the tactics of using physical force by police officers during interventions with individuals exhibiting non-standard behaviours resulting from mental disorders or intoxication. The primary objective of the research was to determine how professional experience differentiates the choice of specific techniques and the attitudes of officers. The study was conducted in 2025 using a diagnostic survey method on a sample of N=303 prevention police officers from the Silesian garrison. The results confirmed that length of service is a crucial variable determining the safety and professionalism of actions. Officers with the shortest service record (1–3 years) statistically more frequently employ high-risk techniques, such as torso compressions or striking techniques. The analysis revealed a process of evolution in professional attitudes: while the „warrior” archetype focused on dominance prevails in groups with up to 9 years of service, the „guardian” archetype, characterized by restraint and a tendency toward de-escalation, crystallizes after 10 years of service. Professional experience facilitates better recognition of medical risks and a reduction in unnecessary violence. The findings highlight the necessity of modifying training programs for novices to eliminate dangerous tactical habits.
