U.S. Army

The U.S. Army is presented as both the immense operating machinery behind the Tokwe Atoll test and the authority that regulates access to its secrets. Its facilities make the test site function like a self-contained settlement; its badges, guards, and security personnel determine who may approach the laboratory and the shot tower. The contrast between impressive logistical capacity and tightly controlled information gives the U.S. Army a defining place in the narrator’s experience of the atoll.

Scope and logistical reach

At Laboratory Field, which Americans shorten to Lay Field, the U.S. Army has transformed one island of Tokwe Atoll in ninety days. The installation accommodates piloted and nonpiloted aircraft and includes an airfield, athletic fields, movie theatres, a chapel, a clothing store, officers’ and enlisted men’s beach clubs, a library, hobby shops, a maintenance hangar, a landing pier, a mess hall, a dispensary, a post office, a laundry, and a power plant. Quarters for the Commanding General stand among these facilities. The scale is not just architectural: the post has ninety baseball teams in ten leagues, a telephone exchange capable of handling more than 6,000 calls per day, and a mess serving 9,000 meals daily. Buses and a radio station operate around the clock. The narrator, comparing the organization to London, registers a military system able to provide ordinary civic services on an extraordinary scale.

Access to the test and its technology

The U.S. Army controls the credentials that let the visiting party move through this extensive installation. The narrator, Dalby, and Jean wear plastic badges bearing their photographs and descriptions; a large Q grants them entry even to secret laboratory areas. The badge makes access explicit and conditional: they may observe because the military has authorized them, not because the facilities are open to outsiders.

An Army major accompanies the visitors and explains the device scheduled for the test. He describes a fractional critical bomb: high explosive compresses a small sphere of uranium-235 or plutonium so that a smaller quantity can produce the required explosion. He also discusses ways of dispensing with tritium and refrigeration, changes that make the bomb cheaper and easier to produce. The explanation places the U.S. Army inside the practical, technical presentation of the test, while the narrator’s limited interest in the lecture’s scientific details marks the gap between official exposition and what he is trying to understand.

Perimeter and military security

The shot tower is surrounded by a security landscape of cables, pipelines, cameras, and armed protection. A twenty-foot electric fence encircles it; white-helmeted police stand watch with Alsatian dogs, while a white amphibious jeep waits beside the sole gate with a machine-gun mounted through its modified awning. Farther out, small figures adjust automatic cameras across the flat sand. The tower itself carries red-painted girders and equipment associated with the test, and a three-man lift travels down its structure. The U.S. Army’s presence is therefore not confined to offices or explanations: it shapes the physical conditions under which observation takes place.

The narrator’s later encounter with an elderly man in a brigadier’s uniform brings military authority into a more personal register. In a room marked Medical Officer Security Division, the Brigadier sits behind a desk with breakfast set out and gestures the narrator toward an armchair. He later displays a deportation order said to bear the Secretary of State’s signature and tells the narrator that he is being exchanged for two airmen who know senators, but sent back to Hungary rather than England. The scene connects a uniformed security environment with the narrator’s confinement and threatened removal, though the order itself is attributed to the Secretary of State rather than presented as an Army document.

Intelligence, exchange, and the Army beyond the atoll

The U.S. Army also enters the book through the narrator’s use of documentary cover. To protect Grenade, he arranges for a contact with access to U.S. Army documents to insert a paper portraying Grenade as an Army agent investigating forged U.S. military scrip. The narrator then leaks that information to an American Express detective and a senator’s second secretary; after charges against Grenade are dropped, the forged papers are destroyed. This is a fabricated identity built from the credibility of Army records, not evidence that Grenade actually served the U.S. Army. The episode shows how institutional documentation can be turned into an instrument of espionage and protection.

The Army’s appearance extends into the book’s supplementary material: the cocktail recipes are reproduced by permission of Master-Sergeant J. B. Revelli, U.S. Army. Among them are the Tokwe Twist and the Manhattan Project. That brief credit links military life to the ordinary rituals surrounding the test, while the recipes’ names carry the setting’s wartime and atomic associations into an otherwise domestic form. Across the installation, the security scenes, and the appendix, the U.S. Army is rendered through systems of provision, authorization, force, and recordkeeping.
