A method comprising attenuating, while involved in a human adversarial situation, one's own emanated electromagnetic field at frequencies less than about 1 gigahertz by wearing one or more articles of apparel that include an electromagnetically shielding fabric, which shielding fabric comprises a substantially continuous system of conductive fibers combined with a non-conductive fabric and attenuates the emanated electromagnetic field at frequencies less than about 1 gigahertz, wherein said attenuating one's own emanated electromagnetic field at frequencies less than about 1 gigahertz decreases the likelihood of one's own emanated electromagnetic field alerting or cueing a human adversary and thereby decreases the likelihood of that emanated electromagnetic field affecting progress or an outcome of the human adversarial situation.
