PRACTICE EXERCISE FOR LESSON 3
You have just finished reading the instructional material for lesson 3. This lesson covered how to
operate the M3A4 smoke generator. We discussed how to fuel and perform before-operation safety
checks, starting procedures, and during-operation checks, and stopping procedures with after-operation
services on the M3A4 smoke generator. Also covered were the procedures for operating the M3A4
smoke generator under unusual conditions. It is now time to check your understanding of the lesson.
This is done by completing the practice exercise below. All of the questions are multiple-choice and are
intended to measure your understanding of the procedures used in performing the task. There is only
one correct answer to each question. Try to answer all of the questions without referring to the lesson
materials.
When you have completed all of the questions, turn the page and check your answers against the
correct responses. Each correct response is referenced to specific portions of the lesson material so that
you can review any questions you have missed or do not understand. When you have completed this
practice exercise, you should review all of the subcourse material before starting the examination.
