The U.S. Defence Department has, for the first time, admitted that it carried out race-based tests on U.S. troops as part of its research about mustard gas. The U.S. Government used Black soldiers as human guinea pigs in chemical experiments during World War II, according to a new NPR report. Around 60,000 U.S. soldiers were enlisted in a classified chemical weapons testing program in which soldiers were enclosed in gas chambers and exposed to chemicals. “They said we were being tested to see what effect these gases would have on Black skins,” Rollins Edwards, a U.S. Army soldier during World War II told NPR. “You had no choice. You did not know where you were going. They didn’t tell you anything,” Edwards added.
