named area of interest(A named area of interest is a point or area along an avenue of approach or mobility corridor where activity will confirm or deny a particular course of action. Named areas of interest can be a specific point on the ground, a specific movement route, or an area. When possible, named areas of interest are placed in numbered sequence along an avenue of approach or mobility corridor. This facilitates the calculation of movement times between specific NAI, and limits confusion as to the specific avenue or corridor under consideration. NAIs may also be significant terrain features which are unknown to the commander. fas.orgPX_Ranger)
