I don't want to place artbrooks at the pillar but this is information I had asked for previously, i.e. do other militaries have the same problems and in what way is the US more culpable?

Here it is again:

1: For example, the first RN ship to be sunk in WW2 was the submarine HMS Oxley, sunk by another British submarine, HMS Triton - how could that have happened?

2: In 1982 in the Falklands, the battle between Company A and Company C of the 3rd Battalion, Parachute Regiment, caused least 8 casualties - who messed up there?.

3: And when British soldiers Corporal Stephen John Allbutt and Trooper David Jeffrey Clarke were killed in 2003 when their Challenger II tank came under fire from another British tank in a nighttime firefight, what did they do wrong?

Were these questions satisfactorily answered? Do the military AND the populace know how these incidents came about? Have they ensured it will never happen again?
