Main effort
Unit assigned to the most critical action
From Wikipedia, the free encyclopedia
In maneuver warfare doctrine, the main effort is the unit assigned responsibility for accomplishing the action most critical to the overall success of a command's mission. It serves as the focal point upon which converges the combat power of the force, and receives priority support of any kind when requested. While a commander always designates a main effort, it may shift during the course of an operation as events unfold.[1][2]
