From Wikipedia, the free encyclopedia

Hunter-Killer teams of armored fighting vehicles are scout vehicles and tanks operating in concert, suited respectively as "hunters" and "killers". For instance, in U.S. land forces, the 19D (cavalry scouts) of a team go in search of enemy positions, and flush the enemy into a designated kill zone where the 19K (armor, i.e. Abrams tanks) are waiting to inflict more damage on the enemy than the "hunters" alone could hope to.
