Madness.

The Army has deleted a tweet posted Thursday afternoon referring to “chinks” in the armor of its Special Operations capabilities after receiving numerous accusations of racism.

The tweet read: “Chinks in special ops’ digital and physical armor poses challenges, experts say.” It included a link to an Army news release with a similar headline that has since been changed. A search on Google Friday morning still showed the old headline.

The Army, whose main Twitter account has 589,000 followers, used the definition of the word that means a weakness or vulnerability — a common expression when discussing security issues. The Washington Post, New York Times and other major publications all use it on occasion, including recently.

But the word “chink” also can be used as a racist term referring to individuals of Chinese descent, as numerous people pointed out to the Army on Thursday night.
