the US Army Field Manuals forbid it:
In late 2006, the military issued updated U.S. Army Field Manuals on intelligence collection (FM 2-22.3. Human Intelligence Collector Operations, September 2006) and counterinsurgency (FM 3-24. Counterinsurgency, December 2006). Both manuals reiterated that "no person in the custody or under the control of DOD, regardless of nationality or physical location, shall be subject to torture or cruel, inhuman, or degrading treatment or punishment, in accordance with and as defined in U.S. law."[10] Specific techniques prohibited in the intelligence collection manual include:
- Forcing the detainee to be naked, perform sexual acts, or pose in a sexual manner;
- Hooding, that is, placing hoods or sacks over the head of a detainee; using duct tape over the eyes;
- Applying beatings, electric shock, burns, or other forms of physical pain;
- Waterboarding;
- Using military working dogs;
- Inducing hypothermia or heat injury;
- Conducting mock executions;
- Depriving the detainee of necessary food, water, or medical care.[11]
