Correct. And Cyber-based attacks are much less visible and easier to hide than overt attacks e.g. a cruise missile. But as things get more automated, the attack surface and concomitant damage will only increase. This could have very real military effects. Suppose your supply lines/defense contractors are targeted by foreign digital attackers. Even if your Military itself uses secure communications and infrastructure, if their dependents are disrupted, it will directly impact their effectiveness.
