The Operation Steel Trap Badge is a cosmetic item for all classes. It is a gray disk featuring a bald eagle facing right with its wings open and a bomb hanging on two chains.
This item is awarded to players when they complete their first mission of the "Operation Steel Trap" Tour of Duty in Mann Up mode. It tracks a player's progress through the various Mann vs. Machine missions, and its level increases based on the number of Tours completed.
