A great example based on recent events... All these "patriots" storming the capital in their weekend warrior kit. If I was a real bad dude, I would have dressed like someone that works at congress when I went in and stole whatever electronics I thought had intel. Which btw did go missing. That is grey man, getting in getting your shit done, and not standing out, because you researched, observed, and knew what you were doing. Not your Fast Helmet & plate carrier with all your dipshit coolkid morale patches.
Showmanship doesn't equal Tradecraft, usually the opposite.
EDIT: P.S. One last thing, stow that ugly F'ing backpack in your vehicle, many places in the city won't let you carry in a backpack. If I see someone with a pack, that is the first dude I would mug/loot.
