The program, which is taught by Tactical Energetic Entry Systems (REES), examines a wide spectrum of breaching options. It addresses the correct and efficient use of the more common tools and also innovative gear and tactics. Techniques for using the various tools are taught, along with the circumstances that warrant the use of specific tool types. The range of breaching techniques taught include mechanical breaching (ram, Halligan, and sledgehammer); saw entry (chainsaws and rescue saws); ballistic breaching (shotgun); and thermal breaching (torch for cutting heavy metal). The curriculum incorporates breaching options beyond the initial entry point, recognizing that there may be fortified doors inside the building or other exterior obstacles that must be overcome before reaching the entry point. The program gives attention to the analysis of various types of targets and construction materials/techniques. After learning proper tool handling and when to use various tools, students are assigned various exercises in which they face simulated breach points that require them to decide which breaching tools to use and how they are to be used, followed by the effective and safe use of the tools in making breaches. The article advises that formal training in breaching will not only lessen an agency's exposure to liability, but also makes a team more efficient at gaining entry and increases the probability of a safe, effective conclusion of the mission.
