"The fields are full of dead sons and husbands. Somebody wasn't discharging their duty of care to their men."

I know that the military experience of the "Muskets" is extremely limited and their understanding of it is even smaller but the above "Muskets" quote does beg the following question:

Where the hell do you get the rather woolly idea that in time of war when face to face with your enemy that anyone's armed forces anywhere in the world has a "duty of care" to their men? After all "Musket" old bean it was the "Somebody" that you refer to who was directed and ordered to deliberately and purposefully put you in harms way FFS.
