text: This tactic has been around a while, hence the reason we roll with 'sterilized' gear (i.e. no logos, tapes/tabs or anything like that) in public. In urban areas call signs are typically semi-normal sounding. My personal favorite is guitar brand names. (Gibson, Washburn, Paul, short for Les Paul and so on.) To anyone not in the know, it sounds like people just using their own last name and creates a bit of a hurdle for them to really try to find out things. Having experience in OSINT has really benefitted us in the way we conduct ourselves.
