Of course you are right. Then again, apparently the heat of the battle makes the soldiers with some conscience get the heck out asap, some in surviving cowardice, others shocked and panicked. The step further to complete mission regardless of one´s life, very well could be accomplished with a little software/hardware combination. I mean one thing is creating super expensive supersoldiers and another cheap hardware addons for mass soldiers with clear beliefs that is not the addon, is them who are convinced.
But stop with all this war bullshit, the applications are so wide that the possibilities really depend more on the imagination to look for an specific application.
And thanks for the post, it should make all of us think a little more about what is really going on in the world.
