    Chapter 1

    Basics

    CCD is th e u se o f materials an d te ch niq ue s to h id e, b len d, d isg uise, d ec oy , o r d isru pt th e

    appea ranc e o f m ilita ry ta rg ets and /o r th eir b ackg rounds . CCD help s p revent an enemy

    from detecti ng o r identi fy ing f ri endly t roops, equ ipmen t, act iv it ie s, o r in sta lla tions .

    P ro perly d esig ned CCD te ch niq ue s tak e a dv an ta ge o f th e immed iate en viro nmen t an d

    natu ra l a nd a rtific ia l mate ria ls . One o f th e impera tiv es o f curre nt m ilita ry doc trin e is to

    con se rv e frie nd ly stre ng th fo r d ec is iv e a ction. Such con se rv ation is a id ed th rough sound

    ope ra tions s ecurity (OPSEC) and p ro te ction from a tta ck . P ro te ction in clude s a ll a ctions

    th at make so ld ie rs , e qu ipmen t, a nd units d iffic ult to lo ca te .

    DOCTRINAL CONSIDERATIONS

    1 -1 . CCD deg rade s th e e ffe ctiv enes s o f enemy re connais sanc e, s urv eilla nc e, a nd ta rg et-

    acquis iti on (RSTA) capab ilit ie s. Sk ill ed observe rs and sophis ti ca ted senso rs can be

    defea ted by obscu ring te llt ale s igns ( signatu re s) o f uni ts on the battl ef ie ld . P reventing

    dete ction impairs enemy e ffo rts to a ss es s frie nd ly ope ra tiona l p atte rn s, func tions, a nd

    capabilities.

    1 -2 . CCD enhance s frie nd ly surv iv ab ility by reducing an enemy s ability to d ete ct,

    id en tify , a nd engage frie nd ly e lemen ts. Surv iv ab ility encompass es a ll a ctions ta ken to

    con se rv e personnel, fa cilitie s, a nd supplie s from the e ffe cts o f enemy weapons and

    actions . Surv iv ab ility te chnique s in clude u sing phy sic al measu re s su ch a s fighting and

    p ro te ctiv e pos itio ns ; nuc le ar, b io logic al, c hemic al (NBC) equ ipmen t; a nd a rmo r. The se

    actions include in te rr ela ted tacti ca l counte rmeasures such as d ispe rs ion, movemen t

    te chnique s, OPSEC , commun ic ations s ecurity (COMSEC), CCD, and smoke ope ra tions

    (a fo rm o f CCD). Impro ved su rv iv ab ility from CCD is n ot re stricted to combat

    ope ra tions . Benefits a re a ls o deriv ed by denying an enemy th e colle ction o f in fo rmation

    about f ri endly forces dur ing peace time .

    1 -3 . D ecep tio n h elp s mask th e rea l in ten t o f p rimary combat o pe ratio ns an d aid s in

    a ch ieving su rp rise . Decep tion counte rmea su re s c an delay e ffe ctiv e enemy re ac tion by

    d isgu is ing in fo rma tion about f riend ly in tentions, capab ili tie s, obj ec ti ves, and loca tions o f

    vuln erable units a nd fa cilitie s. Conve rs ely , in te ntiona lly poo r CCD can p ro je ct

    mi slead ing informat ion about f ri endly ope ra tions . Success fu l tactical decep tion depends

    on s tringent OPSEC .

    1 -4 . Smoke and obs cu rants a re e ffe ctiv e CCD tools and g re atly enhance th e e ffe ctiv enes s

    o f o th er tra ditio na lly p as siv e CCD te chnique s. Smoke and obs cu rants c an change

    RESPONSIBILITIES

    1 -5 . Each sold ie r is re spon sib le fo r c amoufla ging and conce aling h imse lf a nd h is

    targ et. Add itio nally , a th oro ug h knowled ge o f CCD and its g uid in g p rin cip le s allows a

    soldier to easily recognize CCD as employed by an enemy.

    1 -6 . A commander is resp on sib le fo r CCD o f h is u nit, an d n on comm issio ned o fficers

    EVALUATION

    1-13. CCD tra in ing should be re alis tic and in te gra te d w ith a unit s tra in ing eva lu ations.

    Employ th e fo llow ing te chnique s to enhance tra in ing eva lu ations:

    .

    Hav e small-u nit lead ers ev alu ate th eir u nit s CCD effo rts from an en emy s

    view point. H ow a position looks from a few meters aw ay is probably of little

    importance. Evalua to rs should consider the following:

    . C ould an approaching enem y detect and place aim ed fire on the position?

    . From w hat distance can an enem y detect the position?

    . Which CCD principle w as ignored that allow ed detection?

    . Which CCD technique increased the possibility of detection?

    .

    Use b in oc ulars o r n ig ht-v isio n o r th ermal d ev ice s, when p ossib le , to sh ow a unit

    how it w ould appear to an enem y.

    .

    Use pho to grap hs a nd v id eo tap es, if av ailab le, o f a u nit s d ep lo ymen ts an d

    positio ns a s a me thod o f s elf-e va lu ation.

    .

    Incorpo ra te g round- su rvei llance- rada r (GSR) teams in t ra in ing when possib le . Le t

    the troops know how GSR works and have them try to defeat it.

    OTHER CONSIDERATIONS

    1 -14. Wa rfa re o fte n re su lts in p ers onne l lo sse s from fra tric id e. F ra tric id e compels

    1 -1 6. When emplo yed co rre ctly , e xp ed ien t CCD coun te rmea su re s are o ften th e most

    AVO ID ING DETECTION

    identi fy ing a t arge t. S imp ly avo id ing iden tif icati on i s o ft en suf fi cient to increase

    detection or identif ication:

    .

    Id en tify th e e nemy s d ete ctio n c ap ab ilitie s.

    .

    Avo id dete ction by th e enemy s routin e surv eilla nc e.

    .

    Take counte rmeasure s aga in st th e enemy s s en so rs.
