LESSON 2
AREAS OF OPERATION/INTEREST AND TERRAIN ANALYSIS
Critical Tasks: 301-336-4000
01-3381.01-4012
01-3381.01-4013
OVERVIEW
LESSON DESCRIPTION:
In this lesson you will learn the criteria used to identify an area of operations
(AO) and area of interest (AI), procedures for assigning them, and how to perform
the terrain analysis step of the IPB process.
TERMINAL LEARNING OBJECTIVE:
ACTION:
Define the AO and AI, list the factors that impact on the dimensions of
the AO and AI, determine a named area of interest (NAI), define terrain
analysis, identify gaps in terrain data, develop terrain factor
overlays, and develop avenues of approach for both friendly and hostile
forces.
CONDITION:
You will be given narrative information and illustrations from FM 21-
23, FM 34-1, and FM 34-130.
STANDARD:
You will perform terrain analysis and determine both the AO and AI for
both forward and rear echelons in accordance with the provisions of FM
34-130.
REFERENCES: The material contained in this subcourse was derived from the following
publications: FM 21-33, FM 34-1, and FM 34-130.
INTRODUCTION
Weather and terrain have more effect on battles than any other physical factor, to
include weapons, equipment, and supplies. The terrain on which battles are fought
will present opportunities for both sides. Most battles have been won by the side
that used terrain to protect itself and to reinforce the effects of fires used to
destroy the enemy. To be effective, commanders must understand the aspect of
terrain.
