That was a very, very tame version of waterboarding.
I was captured during the evasion portion of SERE, handcuffed and a hood placed over my head. We were loaded onto a truck and driven a mile or so to another place where I heard shouting and screaming.
Two men laid me down on my back, onto a board and tightly strapped every part of my body to it. Ankles, knees, waist, chest, and two places along my arms. Heavy straps, and I found them unbreakable.
Then the hood was removed and I saw a man dipping a large beach towel into a bucket of water. Beside him was another with a waterhose. The towel was folded several time then suddenly placed over my entire face and was held very tight with the man kneeling over me, his hands on either side of my head holding the towel very tightly over my face.
I could not breath. I could not move. All the while the other man was pouring the waterhose over the towel. After what seemed like eternity they released the towel and I gasped for breath.
Then they started asking another man, "what aircraft do you fly? what was your mission?" etc.
When he refused to answer, they placed the towel over my face again and started pouring water over it.
On the fourth run, I lost consciousness.
When I awake there was a Corpsman or doctor checking my pulse and ensuring my airway was open...then to "the boxes" where I was awarded my War Criminal number.
The man was awarded a 100% PTSD disability.
Such an experience will permanently rewire your brain.
