Business is not really like this. First, if everyone doesn't go home, you're going to have a major problem with OSHA. Next, there is rarely a singularity of purpose around a strategy and viable, co-operative alternatives are possible. Next, crushing all your competition would lead to an un-beneficial monopoly, so it's not really a worthwhile fight. Finally, war, and specifically combat are high stress and traumatic experiences that are not sustainable for more than a few months at a time. Humans can act in this way, and maybe the CEO is in this pure fight/ flight/freeze/posture mode, but it's not great to lead a major company there.
That said, there is a lot we can learn from the military, but this "business as war" analogy is pretty absurd. Does it mean the workers are mercenaries? If a worker leaves the company, are they a traitor? Maybe I'm reading too far into it, but let's leave war to the military!
