The Advanced Law Enforcement Rapid Response Training organization (ALERRT) made up  of representatives from the Texas State University, the San Marcos Police Department, and the Hays County Sheriff’s Office came into existence as a direct result of the Columbine High School tragedy in 1999. This incident demonstrated a need for increased training for first responders and civilians alike in active shooter response. Since its inception in 2002, the ALERRT organizations has become a national leader in civilian response to active shooter events (CRASE) training. In 2013, the FBI adopted their model and began providing “train the trainer” courses nationwide for law enforcement personnel. The program is designed around the simple acronym ADD, which stands for AVOID, DENY, and DEFEND.

In 2020, Patriot Defense Training became a subject matter expert in this program and has since been offering this valuable training to schools, churches, business, and organizations community wide. Patriot Defense Training reinforces the ADD acronym through offering several unique blocks of instruction. These stand-alone training blocks can be taught independent of each other or as a collective whole depending on the needs and interest of those requesting the training.
