Horrible comparison. First, it's not uncommon (historically) for bad soldiers to have been executed. In Russian history alone, I can find examples of that (Trotsky's decimation in the Red Army, based of course on the Roman practice). Second, in this case the poor performers aren't executed. They're let go, usually after being put on a pip (which can be viewed as a notice to look for another job). They can improve their performance in another job (if someone is smart, but doesn't get these things done it's a wake up call for them to establish better discipline). Similarly, in the military poor soldiers aren't usually sent into front line battles (being delegated to secondary roles).
