@CWO:
He was definitely a lucky fellow. There was another A-bomb test back in those days which included an exercise by US tank and mechanized infantry units to test out the concept of armoured forces exploiting a breach in a simulated enemy line created by the use of a tactical nuclear weapon. The exercise, as I recall, is mentioned in Richard M. Ogorkiewicz’s book Technology of Tanks, and I think the armoured force in question was designated Task Force Razor.
I shudder to think of the price paid by our service personnel back then. In the same vein, another winning idea from the era was the “Davy Crockett atomic mortar” (actually a recoilless rifle):

The Davy Crockett’s chief shortcoming was its inability to hurl the nuclear projectile far enough to ensure the gun crew didn’t fall victim to their own weapon. Key takeaway from the article:
“Since the warhead also posed a threat to the crew firing it, the Army recommended that soldiers manning the Davy Crockett select firing positions in sheltered locations, such as the rear slope of a hill. Soldiers were also encouraged to keep their heads down to protect themselves from the warhead’s detonation.”
Not mentioned in the article is a quote from a soldier who served on a Davy Crockett crew, which I heard years ago. He said the most valuable piece of equipment in that weapon system was an e-tool, used by the crew to dig foxholes in the event they had to fire the weapon.
