Using that article to suggest the USA gassed their own people is absolutely ridiculous.
how about this article?

The Department of Veterans Affairs has reported that military scientists tested hundreds of chemical and biological substances on them, including VX, tabun, soman, sarin, cyanide, LSD, PCP, and World War I-era blister agents like phosgene and mustard.

or this one?
When the Second World War began, there was a new urgency to research poison gases, and the work focussed intensively on mustard gas and similar chemicals. In 1941, President Franklin D. Roosevelt appointed Alfred Richards, a respected pharmacologist, to coördinate the wartime medical research. A year later, Richards wrote to the Secretaries of the Army and the Navy, asking their permission to use soldiers as test subjects. “In the study of vesicant gases, investigators are confronted by one major obstacle, namely, that the skin of man is so different anatomically from that of laboratory animals that the latter are relatively useless as subjects for experimentation,” he explained. He argued that human experiments with poison gas were necessary and could be done safely. “In the hands of competent experimenters much can be learned concerning the prevention and treatment of gas burns in men without subjecting them to more than relatively trivial annoyance or disability,” he promised.
Using a Freedom of Information Act request, The New Yorker was able to obtain his letter (click on the documents to expand):
At Edgewood Arsenal, in Maryland, the Army built a gas chamber to advance its clinical research. The chamber—an upgrade of an earlier model—occupied a corner of Building 326, which also housed the Officers’ Club. The structure’s walls, made of tile and brick, gave it a vaultlike appearance. Its door was airtight and forged out of thick metal; it had been salvaged from a First World War Navy ship, as was a porthole that served as its sole window. The chamber was a perfect cube, nine feet in all dimensions. Inside, the only source of light was a hundred-watt bulb mounted behind an explosion-proof shield. No more than seven men would be in the room at any given time. “It has been one of the guiding principles of gassing chamber design at Edgewood to have the animals or subjects occupy less than five percent of the chamber volume,” a classified report from the time, “Gassing Chamber for Human Tests: Construction and Operation,” notes. Army scientists knew from experience that too many people caused the concentration of gas to shift in unpredictable ways.
The classified report explains that the chamber’s equipment was designed to run “completely automatically,” with an attendant necessary only to manipulate the dials and to observe the glass bubblers and the pressurized containers and the ducts used to control the flow of gas. Here is a picture, taken in July, 1944, and included in the report:
