b. Disconnect the firing device from the wire.

c. Replace the shorting plug dustcover on the firing wire connector.

d. Replace the dustcover on the firing device connector.

e. Keep possession of the M57 firing device.

f. Untie the firing wire from the firing site stake.

g. Move to the mine.

h. Remove the shipping plug priming and separate the blasting cap from the mine.

i. Reverse the shipping plug.

j. Screw the shipping plug end of the into the detonator well.

k. Remove the firing wire from the site stake.

l. Place the blasting cap into the end of the wire connector.

m. Roll the firing wire on the wire connector.

n. Lift the mine from its emplacement.

o. Secure the folding legs.

p. Repack the mine and all the accessories in the M7 bandoleer.

SOLDIER'S MANUAL CROSSWALK: This task does not differ from task numbers 071-325-4425 and 071-325-4426 in STP 21-1-SMCT pages 191 and 206 and FM 23-23 M18 and M18A1 Anti-Personnel Mine (Claymore) .

EQUIPMENT REQUIRED FOR POINT: Inert M18A1 Claymore mine, firing wire and blasting cap, M57 firing device, M40 test set, M7 bandoleer, two 1-foot stakes, stopwatch, field table, sandbags, and FB Form 20-24-R.

SITE SETUP: Place one M7 Bandoleer containing an inert M18A1 Claymore mine, an M57 firing device, an M40 test set, and firing wire with blasting cap (inert) at the test site. Drive one stake into the ground at the firing site and one at the mine installation point. The distance between the firing point and emplacement point must be no less than 16 meters. Place an aiming point 50 meters from the mine emplacement point.

INSTRUCTIONS TO CANDIDATES

"Let me have your attention. At this point, you are required to employ an M18A1 Claymore mine and recover an M18A1 Claymore mine. You will install, simulate firing, and then recover an M18A1 Claymore mine. You have 7 minutes to install the Claymore mine and 5 minutes to recover it. The simulated firing of the Claymore mine is not timed but is scored."

If there are any questions, repeat the instructions but do not elaborate on what you have read. At this time, the scorer will tell the candidate where the mine is to be emplaced, the kill zone, the aiming point, and the firing position.)

"Begin."

Point L-2 M-21 Anti-Tank Mine

M21 AT mine and components

Task 1: Install/Remove an M21 Antitank Mine

TEST CONDITIONS: During daylight, given an M21 mine (inert), M607 fuse (inert), M120 booster (inert), extension rod, M26 arming wrench, entrenching tool, and an area where the mine is to be placed.

TEST STANDARDS: Install and arm the mine within 4 minutes. Then disarm and recover the mine within 3 minutes.

SOLDIER'S MANUAL CROSSWALK: This task does not differ from task number 051-192-1008 in STP 7-11BCHM14-SM-TG.

EQUIPMENT REQUIRED FOR POINT M21 Antitank mine, M607 fuse, M120 booster, extension rod, M26 arming wrench, entrenching tool, stopwatch, field table, pencil, clipboard, and FB Form 20-25-R.

SITE SETUP: Provide equipment and material laid out at the installation point. Provide soft soil at the installation point for this test.

INSTRUCTIONS TO CANDIDATES

"Let me have your attention. At this point, you are required to install/remove an M21 antitank mine. You will dig a hole and install, arm, and camouflage the M21 antitank mine within 4 minutes. You will then disarm and recover the mine within 3 minutes. Do you understand what you must do?"

If there are any questions, repeat the instructions but do not elaborate on what you have read.

Station L Pre-Test
1. Grid coordinate GL 1234 5678, what does GL refer to?

2. You are plotting GL 1234 5678, what are the first two numbers measured?

3. What kind of grid coordinate is this?

4. An 8-digit coordinate is accurate to ___ meters?

5. You have plotted two 8 digit coordinates, you are at the first one and must land navigate to the second. How do you measure this grid azimuth with a protractor?

6. You now have a grid azimuth of 135 degrees. Why can't you use that setting on your compass?

7. Your grid azimuth is 135 degrees. You must convert to a magnetic azimuth, where do you find the G-M angle to do this?

8. Your G-M angle is 7 degrees to the west, so magnetic north is 7 degrees left of your grid north. What rule do you use to convert 135 degrees grid to magnetic?

9. What does LARS stand for?

10. If your G-M is 7 degrees to the west, and your grid azimuth is 135, what is your magnetic azimuth?
