They designed deadly, silent biological dart guns and hid them in fountain pens and walking sticks. They compressed lethal bacteria into suit buttons that could be worn unnoticed across borders. They rigged light fixtures and car tailpipes to loose an invisible spray of anthrax.
They practiced germ attacks in airports and on the New York subway, tracking air currents and calculating the potential death toll.
But they weren't a band of al-Qaida fanatics, or enemies of any kind. They were biowarriors in the U.S. Army's Special Operations Division at Fort Detrick.
From 1949 to 1969, at the jittery height of the Cold War, the division tested the nation's vulnerability to covert germ warfare — and devised weapons for secret biological attacks if the United States chose to mount them.
A few years ago, its story — never before told in detail — would have seemed a macabre footnote to U.S. history.
Now, after the Sept. 11 attacks, the anthrax mailings and a steady stream of government warnings on terrorism, the fears of the 1950s have returned, and the experiments of Fort Detrick's covert bioweapons makers suddenly resonate in a new era. In the biological realm, there is little that any terrorist group could concoct that Fort Detrick's "dirty tricks department," as veterans call it, didn't think up decades ago.
But because of the division's scant record-keeping and the fast-disappearing ranks of its aged scientist-warriors, the knowledge it acquired is being lost to history.
Dead in 25 seconds
One of the few survivors is Wallace Pannier, 76, who remembers standing in a Frederick County field watching sheep shot with what the Army called a "nondiscernible bioinoculator" — a dart gun. The bosses demanded a dart so fine that it could penetrate clothing and skin unnoticed, then dissolve, leaving no trace in an autopsy.
"If the sheep jumped, that meant people were going to jump, too," said Pannier, now living a quiet life tending his flowers and shrubs in Frederick, Md.
Once perfected, the dart gun astonished those who saw it in action. Charles Baronian, a retired Army weapons official, recalls a demonstration at Fort Bragg, N.C.
"Twenty-five seconds after it was shot, the sheep just fell to the ground," said Baronian, 73. "It didn't bleat. It didn't move. It just fell dead. You couldn't help but be impressed."
The rest of the Army's offensive biological weapons program thought big: 500-pound anthrax bombs that could contaminate entire cities. But the Special Operations Division — known at Fort Detrick by its initials, SO — studied biowarfare on a more intimate scale, figuring ways to kill an individual, disable a roomful of people or touch off an epidemic.
Code name MKNAOMI
The existence of the SO Division was revealed only six years after it shut down, in a 1975 Senate investigation into CIA abuses. Senators wanted to know why the CIA had retained a lethal stock of shellfish toxin and cobra venom after President Nixon's 1969 order to destroy all biological weapons stocks. They found that the poisons had come from the SO Division under a CIA-Army project code-named MKNAOMI.
But records show that even CIA bosses were stymied as they tried to get the facts on the SO Division. "The practice of keeping little or no record of the activity was standard MKNAOMI procedure," a CIA investigator wrote. The military offered little help, he added: "The Army has no records on MKNAOMI or on the Special Operations Division."
In response to a Freedom of Information Act request from The Baltimore Sun, the Army said no records of the Special Operations Division could be found. Nor is there any mention at the National Archives, which reclassified Fort Detrick's old biowarfare records after the Bush administration ordered agencies to withhold anything that might aid terrorists.
Few SO Division veterans are still alive. Fewer still are willing to describe their work.
"I just don't give interviews on that subject," said Andrew Cowan Jr., 74, the division's last chief, who is retired and living near Seattle. "It should still be classified — if nothing else, to keep the information the division developed out of the hands of some nut."
Proud of their work
But it is possible to assemble a patchwork portrait from documents obtained by The Sun under the Freedom of Information Act, Senate investigative files and private document collections, including the National Security Archive in Washington and even the Church of Scientology, which long collected material on government mind-control research.
And a few Detrick retirees who worked in the SO Division or collaborated with it spoke sparingly about what they know. Most are proud of their work, pointing out that the Soviet biological program was much larger and also developed assassination tools.
The veterans say that if the biological devices they made were used against humans, they never learned about it. But it is impossible to be certain, they say, because the program was strictly compartmentalized: One worker didn't know what another was doing, let alone what CIA or Special Forces did with the bioweapons.
The 1975 Senate investigation revealed that the SO Division supplied biological materials for several planned CIA attacks, none of which was successful.
In 1960, the CIA's main contact with the SO Division, Sidney Gottlieb, carried a tube of toxin-laced toothpaste to Africa in a plot to kill Congolese leader Patrice Lumumba. But the CIA station chief balked and pitched the poison into a river, a congressional investigation later revealed.
Records suggest, though they do not prove, that the SO Division also supplied germs for CIA schemes to kill or sicken Cuban leader Fidel Castro, and that it came up with the poisoned handkerchief that the agency's drolly-named Health Alteration Committee sent to Iraqi Prime Minister Abdul Karim Qasim in 1963. (He survived.)
Army Special Forces also asked the SO Division to design biological assassination weapons. Fort Detrick's engineers delivered five devices — including the dart gun — collectively known as the "Big Five." But records of what Special Forces did with the weapons remain classified, said Fort Bragg archivist Cynthia Hayden.
Biowarriors were ready
If the work sounds sinister today, there were doubters at the time, too. A 1954 Army document says high-ranking officials — including George Merck, the pharmaceutical executive and top government adviser on biowarfare — wanted to shut down the SO Division because they considered it "un-American."
But Fort Detrick's rank and file rarely voiced such doubts. "We did not sit around talking about the moral implications of what we were doing," said William Patrick III, a Fort Detrick veteran who worked closely with the SO Division. "We were problem-solving."
And if the orders came to unleash the weapons, Fort Detrick's biowarriors were ready.
During the Vietnam War, William Walter, who supervised anthrax production at Fort Detrick and worked with the SO Division on projects, asked British intelligence agents for blueprints of the office occupied by North Vietnamese leader Ho Chi Minh. Plotting a covert germ assault is easier if the room's cubic footage and ventilation system are known, he says.
"We thought if the president of the United States wants to kill somebody, we want to be able to do it," said Walter, now 78 and retired in Florida.
No way of knowing
A gun or a bomb leaves no doubt that a deliberate attack has occurred. But if someone is stricken with a sudden, fatal illness — or an epidemic slashes across a crowded city — there is no way of knowing whether anyone attacked, much less who.
That was the key conclusion of the Pentagon's Committee on Biological Warfare in a secret October 1948 report on covert biowarfare.
At the time, the United States feared a shadowy global enemy, organized in secret cells overseas and on U.S. soil: Communists. Echoing today's fears, the report said the United States "is particularly vulnerable" to covert germ attack because enemy agents "are present already in this country [and] there is no control exercised over the movements of people."
Although it emphasized the threat to America, the report called for offensive capability. "Biological agents would appear to be well adapted to subversive use since very small amounts of such agents can be effective," the report said. "A significant portion of the human population within selected target areas may be killed or incapacitated."
Seven months later, in May 1949, the Special Operations Division quietly opened at Fort Detrick.
Even within the tight-lipped world of Fort Detrick, the SO Division's secrecy was extraordinary. "Most of the people [at Fort Detrick] didn't know what was going on in SO," Pannier said. Fanning out across the country, SO Division officers played the role of bioterrorists in an era before the word had even been coined. Their usual mock weapons were two forms of bacteria, Bacillus globigii (BG) and Serratia marcescens (SM).
Scientists thought both were harmless, though later research found that SM could cause illness or death in people with weakened immune systems.
In an elaborate 1965 attempt to assess how travelers might be used to spread smallpox, SO Division officers loosed BG in the air at Washington National Airport and at bus stations in Washington, Chicago and San Francisco, then tracked its movement using air samplers disguised as suitcases.
Tracking travelers' routes, Fort Detrick scientists plotted on a U.S. map the smallpox cases that would result from a real release.
The next year, without alerting local officials, SO Division agents staged a mock attack on the New York subway, shattering light bulbs packed with BG powder on the tracks.
"People could carry a brown bag with light bulbs in it and nobody would be suspicious," Pannier said. "But when [a bulb] would break, it would burst. The trains swishing by would get it airborne."
The SO Division's report concluded that "similar covert attacks with a pathogenic agent during peak traffic periods could be expected to expose large numbers of people to infection and subsequent illness or death."
Understanding U.S. vulnerability may have been the main purpose of such experiments. But defensive findings had offensive implications. No one had to tell experimenters that Moscow, too, had a subway.
If the subway tests could be explained as defensive, there was no such ambiguity in the SO Division's development of covert biological weapons.
Mysterious characters from Fort Bragg and the CIA came and went at the SO Division, leaving wish lists and checking progress.
Most CIA records on the SO Division apparently were destroyed in 1973 by Gottlieb, the agency's liaison to Fort Detrick. But declassified invoices the division submitted to the CIA give a sense of the work.
Germ dispensers could be concealed in many objects, such as the exhaust system on a 1953 Mercury. ("It might look like a smoky, oil-burning car," Pannier said.) There were invoices for fountain pens, even "1 Toy Dog, 98 cents."
And there were supplies for a "Buster Project." One plan for the dart guns was to knock out guard dogs so U.S. agents could sneak into foreign facilities.
But dogs were not the primary target of the SO Division's creative efforts. "The requirements of the Army Special Forces were the driving force defining SOD activities, and Special Forces' interest included a number of weird things, definitely among which was assassination," a CIA retiree told an agency investigator in 1975, according to a declassified report.
Devoted to assassination
The former CIA man referred to the arsenal that came to be called the Big Five. "The Big Five program was devoted to assassination," said Patrick, who worked closely with the SO Division as chief of product development at Fort Detrick. He calls it "the most sensitive program we ever created at Detrick," and says its details should still be kept secret because they might be useful to terrorists and "embarrassing to the United States."
Detailed descriptions of the Big Five remain classified. But documents show that they included at least one version of the biological dart, dipped in shellfish toxin and fired from a rifle using a pressurized air cartridge.
Among the other Big Five weapons: a 7.62 mm rifle cartridge packed with anthrax or botulinum toxin that would disperse in the air on impact; a time-delay bomblet that would release a cloud of bacteria when a train or truck convoy passed; and a pressurized can that sprayed an aerosol of germs. The fifth is described in unclassified documents only as an "E-41 disseminator."
Of all the old bioweaponeers, Patrick is the only one who still has ties to U.S. biodefense programs, working as a consultant and trainer. But he said the government has made little effort to learn from the work of the Special Operations Division and the larger biowarfare program.
Although bioengineering today could produce more virulent pathogens, "nothing has changed" in the most challenging part of covert biological attack: delivering germs so that they infect people, Patrick said.
"The problem today is there's a huge disconnect between what us old fossils know and what the current generation knows," Patrick said. "The good doctors at CDC [the national Centers for Disease Control and Prevention] don't have a clue about aerosol dissemination, and the military is not much better."
Walter, in Florida, agreed with Patrick's diagnosis. But he said it's fine with him if the dark lessons of Fort Detrick's early days are lost forever.
"When we all die off, that's it," he said. "If anybody with bad intentions got hold of the things we had, it would be disastrous."
