Battles are won or lost through the effective or ineffective use of communications. The enemy
can derive valuable and critical data from the disclosure of military information. Through the
effective use of communications security, we are able to surprise the enemy as well as reduce
susceptibility to enemy attack against our forces. This lesson will teach you how to achieve
communications security as a radio operator. This lesson, as in Lesson 1, is presented in frames.
