Coast Artillery Qualification Exam - Level:  Marksman

The coast artillery qualification exam is designed to test knowledge of basic and advanced coast artillery principals and theory.  Upon completion, this test is submitted to Fort Miles command for review and grading.  You will be notified via mail if you have passed the test, and you will receive the "coast arty" qualification tab for wear on the appropriate level of qualification.  If you do not know an answer, you may skip the question and come back to it at a later time.  Passing requires a grade of 85 percent or higher (at least 106 points out of 124 possible).  Study material can be found in the manuals available at the download section.
