DI SSgt Gaither was quite simply, the meanest and scariest MF I have ever met in my life.
Sir.
I remember "Full Metal Jacket" to be very close to the experience I had at Boot Camp in 1959. About the only thing missing in the movie was the physical violence that was inflicted on us on a daily basis.
The black DI in the photo is Sergeant (E-4) W.W. Almond, and I still remember in vivid detail the ass-whippings he delivered.
