The Human Rights Watch report—as well as accounts given to Senate staff—describe officers as aware of the abuse but routinely ignoring or covering it up, amid chronic confusion over U.S. military detention policies and whether or not the Geneva Convention applied. The Captain is quoted in the report describing how military intelligence personnel at Camp Mercury directed enlisted men to conduct daily beatings of prisoners prior to questioning; to subject detainees to strenuous forced exercises to the point of unconsciousness; and to expose them to extremes of heat and cold—all methods designed to produce greater cooperation with interrogators. Non-uniformed personnel—apparently working for the Central Intelligence Agency, according to the soldiers—also interrogated prisoners. The interrogators were out of view but not out of earshot of the soldiers, who overheard what they came to believe was abuse.
Specific instances of abuse described in the Human Rights Watch report include severe beatings, including one incident when a soldier allegedly broke a detainee's leg with a metal bat. Others include prisoners being stacked in human pyramids (unlike the human pyramids at Abu Ghraib, the prisoners at Camp Mercury were clothed); soldiers administering blows to the face, chest and extremities of prisoners; and detainees having their faces and eyes exposed to burning chemicals, being forced into stress positions for long periods leading to unconsciousness and having their water and food withheld.
Prisoners were designated as PUCs (pronounced "pucks")—or "persons under control." A regular pastime at Camp Mercury, the report says, involved off-duty soldiers gathering at PUC tents, where prisoners were held, and working off their frustrations in activities known as "F____a PUC" (beating the prisoner) and "Smoke a PUC" (forced physical exertion, sometimes to the point of collapse). Broken limbs and similar painful injuries would be treated with analgesics, the soldiers claim, as medical staff would fill out paperwork stating the injuries occurred during capture. Support for some of the allegations of abuse come from a sergeant of the 82nd Airborne who served in both Iraq and Afghanistan. Human Rights Watch quotes him as saying that, "To 'F____ a PUC' means to beat him up. We would give them blows to the head, chest, legs, and stomach, pull them down, kick dirt on them. This happened every day. To 'smoke' someone is to put them in stress positions until they get muscle fatigue and pass out. That happened every day. Some days we would just get bored so we would have everyone sit in a corner and then make them get in a pyramid. This was before Abu Ghraib but just like it. We did that for amusement.
