Chapter XI. Information, Please!

* * * * *
There is much information in the preceding ten chapters. All of it is valuable to the men in "amphib" who man the LCM(3) and the LCVP and it cannot be mastered in just one speedy reading. Certain sections in particular, such as the ones dealing with the boat and engine checks, will stick with you only if you make a real effort to remember them.

To help you review the subject matter more easily this "quiz chapter" has been prepared. Questions on the contents of the book are listed below. Some of the questions are true or false, others are multiple choice, matching, or completion type.

Correct answers to the questions are given at the end of this chapter.
