APPENDIX B
GUNNERY TESTS
There are three gunnery tests: a diagnostic gunnery test, an intermediate gunnery test, and a gunnery skills test. The instructor is responsible for the conduct of all tests, and must ensure that sufficient scorecards or answer sheets are available.
B-1. DIAGNOSTIC GUNNERY TEST
This test is given before and during preparatory training. It is a written test that evaluates the trainees' knowledge of the MK 19 as well as the instruction given. Training units prescribe procedures for the test, and announce scores of those who satisfactorily complete the test. If this test is used, it should be given before range firing. It has a possible score of 100 points. To satisfactorily complete the test, 80 points are required.

B-3. GUNNERY SKILLS TEST
This is a test guide for unit commanders to standardize and maintain MK 19 gunnery skills. It is a nonfiring hands-on test given at the end of MK 19 training. It may be held indoors if facilities are available. Seven stations are used for the skill tests. The test is graded on a GO or NO-GO basis.
a. Instructions for the Gunner's Examination. The following is a guide for giving gunners the skill test.
(1) To organize for testing, assemble the entire unit in one area and orient them as follows:
DURING THE NEXT ____ HOURS YOU WILL TAKE PART IN A PERFORMANCE-TYPE EXAMINATION TO TEST YOUR KNOWLEDGE OF THE MK 19 MACHINE GUN. STAY WITH YOUR ASSIGNED GROUP DURING THE ENTIRE EXAMINATION. INITIALLY, EACH GROUP WILL BE ASSIGNED TO A SPECIFIC STATION. AT EACH STATION, AN ASSISTANT INSTRUCTOR WILL EXPLAIN EXACTLY WHAT TASK OR TASKS YOU ARE TO PERFORM. AFTER BEGINNING THE TASK, IF YOU DO NOT KNOW A STEP OR STEPS, ASK THE ASSISTANT INSTRUCTOR FOR HELP. HE WILL TELL YOU HOW TO PERFORM THE STEP, DEDUCT THE NECESSARY POINTS FROM YOUR GRADE, AND YOU MAY CONTINUE TO WORK. SEVENTY PERCENT IS THE PASSING SCORE.
(2) Organize the unit into seven equal groups that rotate from station to station until all individuals have been tested. Helmet and LBE will be worn for this test. Assign enough assistant instructors to each station to grade and critique each gunner's performance. For ease in marking, give score sheets to each grader and collect the sheets immediately after the test.
(3) At the end of testing for each group, have each grader assemble the soldiers he graded and give them a thorough critique (five minutes).
b. Testing Stations. There are seven stations for gunnery skills testing. All stations except one, six, and seven have intermediate training objectives.
c. Scoring. For tasks at stations one, six, and seven score the soldier GO if all steps are passed (P). Score the soldier NO-GO if any steps are failed (F). If the soldier fails any steps, show what was done wrong and how to do it correctly. For stations two through five, score the soldier GO on a task if he receives no more than one intermediate training objective NO-GO.
