GST refers to backward thinking, cheap, antiquated, flashy ‘because that’s how we’ve always done it” tactics that fail when exposed to opposition, much like knives that are purchased at a gas station. They’re flashy, colorful, look the part, and can perform simple menial tasks. But the second they’re needed in a hostile/survival situation, they crumple and break.
All tactics will are deemed functional and successful until they are tested and tried.
This is HSG’s subtle way of saying “Nah! We aint about that life!” to all the BS garbage out there.
