Active Cameo

The ideal of camouflage is invisibility. However, this is unachievable with current technology, and is difficult to believably maintain while talking/interacting with local people during covert operations. This idea preserves anonymity while allowing normal interaction with local people. The idea can take two forms:

1) Hire celebrities: A military organization should hire celebrities from the area to be invaded to work for them in a part-time capacity. Celebrities who have extensive experience avoiding the public eye should be chosen.

2) Look like celebrities: Solders attempting covert operations should adopt the features and mannerisms of locally-known, rich and reclusive citizens. That way, if they are ever stopped by police while stealing secret documents, they can believably tell the police that they were "indulging an eccentricity" and probably have the authority to do whatever they were doing. Then, they can pull out a late-model cellphone and call their "private helicopter" to extract them before the local police are able to fact-check that it is indeed the celebrity.

edit: this is not normal spying technique because spies try to hire/impersonate nondescript, ordinary individuals rather than celebrities. Celebrities to be hired/impersonated should have instant name- and face-recognition among most of the public.
