I spent much of my last year on active duty teaching CPR, Self Aid & Buddy Care, and Law of Armed Conflict to USAF communications troops preparing for deployments. Including the duty to refuse to obey unlawful orders. I would have guessed it only about 40% or so... but that was Air Force.
There is a joke about an Army General, a Navy Admiral, a Marine General, and an Air Force General in a bar at a Joint Service base. They're bragging about how brave their branches troops are.
The Army General orders one of the Privates to attack and destroy a tank passing the O-Club. Using movement and fire, the private assaults the tank with his M-16, until it runs over and squishes him. The General says, "Now that's bravery!"
The Admiral tells one of the Sailors to attack the tank. Using needle scaler and paint brush, the Sailor attacks the tank and is immediately squished.
The Admiral says, now that's bravery!
The Marine General tells one of the Marines to attack that tank! The Marine draws his Kabar, and stabs the tank track, gets dragged in and both he and his Kabar get squished.
The Marine General says"Now that is bravery!
The Air Force General tells one of the Airman to attack the tank. The airman says "&#%$ you! You're not in my chain of command!"
And the Air Force General says, "Now that's REAL bravery!"
