1. 2 Types of Compasses M2
Lensatic - USMC standard
2. 2 Types of Compass Errors Variation: angular difference between true & magnetic north
Deviation: deflections from a vehicle/electrical equipment
3. Finding Magnetic Azimuth measure angle between Magnetic North and the direction you
are heading.
4. Converting Magnetic Az- Subtract G-M angle
imuth to Grid Azimuth
Grid North = direction of North line on the map's grid
Magnetic North = use compass
5. Steps in Land Navigation us- 1) Orient map and mark your position
ing a map 2) Measure magnetic north to the unknown position
3) Convert that measurement to 0 grid azimuth
4) Move to 2nd position where unknown position is visible and
then orient.
5) Repeat at the 3rd position
6) Draw lines from each unknown position to the known position
creating the "Triangle of Error" or your likely position
6. Column fire team formation Favors flank & maneuverability
Vulnerable to front fire; least amount of front fire provided
7. Wedge fire team formation Flexible; most often used when enemy contact present
8. Skirmishers (Diamond) fire Max firepower to front
team formation Enemy location known
9. Echelon fire team formation protects flanks

10. Tactical Wire Entanglements Used parallel to & along friendly side of final protection line
(XXXX) Breaks up enemy attack formations
Holds enemy in areas covered by defensive fire
11. Protective Wire Entangle- Prevents surprise assaults from points close to defense area
ments (X-X-X-X) Day/Night observation locations
Prevents grenade use
12. Supplementary Wire Entan- Directly in front of Forward Edge of Battle Area (FEBA)
glements (X=X=X=X) Conceals/Break up exact line of tactical wire
Encloses defense positions by connecting protective wire
13. Triple Standard barbed-wire durable obstacle wire
14. Double Apron barbed-wire Easy set-up obstacle wire
15. Low wire entanglement prevent crawl invaders
16. Tangle foot entanglement prevent lane cutting/tunneling; slow down enemy
17. Establishing a Landing Zone 100ft x 100ft; level surface; 5 times height of tallest tree in dis-
(LZ) tance away from said tree
18. Code of Conduct Article 1 I am an American, fighting in the forces which guard my country
and our way of life. I am prepared to give my life in their defense.
19. Code of Conduct Article 2 I will never surrender of my own free will
20. Code of Conduct Article 3 If captured, I will continue to resist by all means available. I will
make every effort to escape and aid others to escape. I will accept
neither parole nor special favors from the enemy.
21. Code of Conduct Article 4 If I become a POW, I will keep faith with my fellow prisoners. I
will give no information or take part in any action which might
