The unit was renamed the LRB from the former Light Reaction Company to adapt to the increase in the unit's manpower and to pursue Anti-Terrorist duties in the Philippines. In 2014, the unit was again renamed into the Light Reaction Regiment due to its heroic stand in Zamboanga in September 2013. Its elevation to a full regiment was formally sanctioned by Defense Secretary Gazmin on January 16, 2014.
