I'll also say that there's a huge difference between IT specialist in the military and Tier 1 Special Forces Operator. One may facilitate killing, but its not a core competency, and you can spend an entire enlistment term doing absolutely nothing that might suggest your relation to a lethal machine; indeed you can do your job and never think about what you might be facilitating. The other exists to kill, and occasionally explicitly murder, and failing to make peace with that reality makes them less effective at their job. Both are ultimately necessary.

I understood the article as reminding folks to actually think about what you might be facilitating, and make your choices accordingly.
