CRITICAL TASKS: 01-5701.07-0002
In this lesson, you will learn about the sources, types, and effects of
TERMINAL LEARNING OBJECTIVE:
Define and describe the sources, types, and effects of EMI.
Given this lesson material, pencil, paper, and no supervision.
To demonstrate competence, you must achieve a minimum of 70
percent on the subcourse examination.
The material in this lesson was derived from the following
publications: FM 24-2, FM 24-18, and AR 105-3.
Maintaining command, control, and communications (C3) in an electromagnetic
environment is a major challenge.
Commanders who try to control and
manipulate the environment gain an advantage for their side to the detriment
of an enemy. The frequency spectrum is very crowded because it has finite
Thus, C3 tasks are harder due to the number and capabilities of
enemy emitters, jammers, and various non-communication emitters. They are
also harder due to unintentional interference by friendly forces. You must
be aware of the effects of EMI and EMP.
