Soldiers in a unit in Alaska have a "tradition" of allowing racial slurs to be used freely on "Racial Thursdays," a soldier told the Army Times.

"When I first got to my unit, someone said we should do 'Racial Thursdays' because it's been a tradition," the soldier, a staff sergeant, told the Times. "It's something they made up where you can say any racist remark you want without any consequences. The platoon sergeant said no, but the (expletive) is still going on."

The unidentified soldier said he filed an equal opportunity complaint.

The Army Times also spoke to another soldier, who gave further details on the alleged practice.

A spokesman for U.S. Army Alaska said he was aware of the allegations and an investigation had been started.

The unit where the practice allegedly takes place is the same one where a Chinese-American soldier killed himself in Afghanistan in October 2011, after being cruelly hazed and taunted with name-calling tied to his Chinese ancestry.
