The pin “Driver” is a symbol of the person who keeps the war machine moving, even when all hell breaks loose around them. He is invisible from the outside, but everything depends on him: speed, maneuvering, the lives of the crew. The skull in the driver's helmet with a cigarette in his teeth is an image of calm amid chaos, cold concentration, and disregard for fear.
The "Tourniquet" pin — the strap that stops bleeding in seconds and buys time to reach a hospital. A badge for anyone who knows the value of first aid.
The "M18 Smoke Red Grenade" pin — a smoke screen that covers a retreat or a maneuver when a few seconds of cover are all you need. A badge for those who know when to disappear.
