"guard election systems" is he saying he's going to have troops at the polls?
Edit: I still don't see any other sources reporting that this is the case and the only thing on that site resembling proof is
In a memo dated Sept. 22 and publicly announced Monday, Hegseth directed defense intelligence officials to mobilize every resource “to defend our election infrastructure from foreign malign influence and ensure that every lawful voter can cast their ballot free from foreign intimidation, coercion, or fear.”
Which doesn't say anything about troops at polls
