Does the exercise take place over a period of time, or just in a day as you would with gas chamber training? Or has that training changed as well?
It has similar results.Panic, feelings of suffocation ,confusion etc. Gas chamber is painful though, burning eyes,skin, mucous membranes. Waterboarding is not painful like the gas chamber. It gives the sensation of suffocating, it is a psychological modality used when urgent and /or lifesaving intel is necessary.Other modalities such as sleep deprivation, isolation and being kept wet, (hosed down periodically) takes time to develop therefore not useful when time is of the essence.
I understand your aversion to waterboarding, much of it is due to mis-information stemming from media bias.
Ask yourself this question: If one of your loved ones was being held by some psychopath, who threatened rape, torture or murder and police had one of his/her accomplices. Time is running out to save your loved one a gruesome death. To what level would you authorize the police to extract information from the accomplice that might save your loved one?
