The Congressional Gold Medal, presented in 2024 to three centenarian veterans, was a recognition not of a precise military accounting but of a kind of service that deserved acknowledgment: creative, courageous, performed under conditions of genuine risk, and kept secret for so long that most of the men who performed it died before the recognition arrived. The rubber tanks have deflated. The speakers are silent. The radio operators who could imitate a stranger’s fist are gone. What remains is the record, now public, of what they did.
## The Equipment Catalog
The physical inventory of the 23rd Headquarters Special Troops was unlike any other American unit in the European theater.
The 603rd Engineer Camouflage Battalion maintained supplies of inflatable rubber equipment that included Sherman tanks, half-tracks, artillery pieces, jeeps, and trucks. Each Sherman tank replica was made from neoprene-coated fabric, designed to be deployed and inflated by a small crew in under twenty minutes using a gasoline-powered compressor. Deflated, a single tank weighed approximately 93 pounds — light enough for two men to carry. Inflated, it stood at the same height and presented roughly the same visual profile as the real vehicle it was imitating.
The care that went into the visual design of these replicas reflected the purpose they served. They would be observed from aircraft and from a distance on the ground. At 2,000 feet altitude, a photographic interpreter looking for evidence of tank concentrations would see what appeared to be armored formations in assembly areas. The rubber tanks cast shadows consistent with their apparent size. They were positioned in ways that matched the tactical logic of real unit assembly, with spacing and orientation that suggested operational readiness rather than random placement.
