7
   

3. PRINCIPLES OF CAMOUFLAGE

8-9

a. Gaining concealment (choice of position, camouflage discipline, construction)
8

(1) Choice of position --

8a

 

(a) Fire mission (field of fire, observation, communications) (b) Other factors (concealment -- background, natural cover, defilade, space, landmarks-cover, obstacles)

 

 

(2) Camouflage discipline

8b

 

(a) Visual (including light and smoke)

 

(b) Sound

Construction --

8c

 

(a) Choice of materials (natural, artificial)

(b) Correct use of materials

b. Camouflage methods (hiding, blending, deceiving)

9
   

4. HIDING AND BLENDING

10-42

a. Natural materials (vegetation -- live and cut -- debris)
10-14
b. Artificial materials (issue materials, flat-tops and drapes, garnishing)
15-20
(1) Flat-top garnishing --
17a
  (a) 80% of center, thinned at edges; 55% of net area
17b
  (b) Application (patterns -- Greek key, u, special)
18
(2) Flat-tops (materials, labor)
19
(3) Color percentages for garnishing
21
(4) Drapes, garnishing (complete to edge; 65% of net area)
20
c. Drapes, flat-tops, screens
22-37
(1) Drapes (substitute for hasty flat-top; conceals type not presence) --
22
  (a) Sizes --
22a
  (b) Use pregarnished nets
22b
(c) Use props to break up form, natural material to blend
22c
(2) Flat-tops (type of screen; conceals presence when correctly erected and tied in) --
23-37
  (a) Erection (parallel to ground, 2 feet above object, extend past concealed area twice height above ground)
27-30
  (b) Types (T/E and Class IV)
26
  (c) Holdfasts
31
  (d) Maintenance and folding
32-33
(e) Embrasures
34
(3) Screens --
35-37
  (a) Slope
35
  (b) Other types
36
  (c) Smoke
37
d. Reduction of tone contrasts (color -- background and distance; texturing -- background)
38-39
e. Disruption of form (irregular outlines)
40
(1) Disruptive patterns (general, vehicle)
41-42
  (a) Vehicle (protective coloration for vehicle not in motion and in well-selected site, where drape is impractical )
42
  (b) Tie in dark part of pattern to shadows of site
42

 

(c) Darker on top, lighter below
42
   
5. DECEIVING
