I think you literally described the IA process.Unfortunately that's a very militaristic mindset that may not exist elsewhere.
It takes a certain level of training to make a 19 year old kid charge a machine gun nest without question in the face of their own death. And we don't hold them accountable by telling them that they are no longer Marines when they survive but couldn't do it.
Perhaps those legislative measures would help.
I, too, get frustrated when an ER doc, when an ICO nurse, says, "This isn't what I signed up for." But I would have a measured level of understanding if a Sub Nuke somehow found their way into an infantry company; and, as an officer, an understanding of when that nuke kid would be more of a liability than a help while we are clearing a house full of bad guys. "Hey kid, why don't you wait in the tree line here, if a bad guy runs past this point- shoot them. And call me if someone else shows up. Here's a radio- do you know how this works?"
Training is going to be the name of the game. Hopefully we have enough time.
