Objectives: This paper describes some operational tactical procedures (OTP) and discusses the results of a 14-year-long study, spanning the period 2003–2016, conducted by the Municipal Police of Cádiz, Spain, which comprised 3 time periods: 2003–2006, when the officers were trained in traditional policing procedures; 2007–2013, when the officers were taught an innovative set of OTP in the form of a basic set of self-defense and arrest mechanisms, different from the traditional policing procedures that rely on martial arts and combat sports; and finally 2014–2016, when the OTP training was discontinued. The aim of this study was to improve policing and reduce officer injuries resulting from interventions in controversial or violent situations, such as problematic arrests. Material and Methods: The study involved 162 police officers and commanders of the Municipal Police of Cádiz, who were in street duty for their first time. There were 8 females and 154 males aged 24–55 years. Three OTP stages are shown as examples. Results: Based on the analysis of “training hours” and “physical interventions in problematic arrests,” the results were: 1) the number of sick leaves in the police was identical according to the number of arrests, and 2) data on sick leaves show remarkable differences among the 3 periods under analysis. Conclusions: The OTP-based training substantially reduced officer sick leaves. The overall reduction in sick leaves in the period 2007–2013 was observed that cannot be ascribed to a decrease in criminal acts, and hence in police physical interventions.
