A soldier in combat deals with life or death in ways which are far more direct than a Boeing aircraft sometimes having its door blown off. Soldiers in combat may choose for people to die as a product of moral vision, not accidents.

But we all know the reality of whether we expect moral pushback from the armed forces for just about anything.

Was it a good deal when hundreds of thousands of bystanders died in Iraq? It doesn't matter. It's not the place of the rank and file to question authority, regardless of constitution this or moral that. The same is true for rank and file engineers.
