Editing Agent handling (section)

==Training==
Agent training often includes techniques of tradecraft such as clandestine [[communication]], including [[cryptography]], the use of [[one-time pad]]s, the construction of [[concealment device]]s, and the employment of [[dead drop]]s. Other elements of tradecraft include elicitation, [[surveillance]] and [[countersurveillance]], photography and the emplacement of audio devices, sensors, or other transmitters. Case officers generally train agents one at a time, in isolation, including only those elements of tradecraft needed to penetrate the target at hand. Case officers will also teach agents how to develop ''cover for status'', and ''cover for action'', meaning how to establish credible pretexts for their presence and behavior while engaged in collection activities. A well-trained and competent agent can conduct his or her clandestine tasks while under close surveillance, and still evade detection. More advanced agent training can include resistance to [[interrogation]].
