Having read the memo--which is basically meeting minutes between the DoD and DHS-- it's seems to be missing an understanding of how much Trump is disliked up and down the ranks. They ultimately did almost nothing in LA. The birthday military parade had clear signs of everyone phoning it in on purpose. Signalgate convinced all but the most diehard MAGA soldiers (not as big a group as you might think) that this leadership is a bunch of clowns.
What this means is that the White House still overestimates how much the military is in their pocket. Good.
From Ur-fascism:
Fascist governments are condemned to lose wars because they are constitutionally incapable of objectively evaluating the force of the enemy.
What's missing from the analysis is that they can't objectively evaluate their own forces, either. As much as they go on about strength and fighting and war, they're actually really bad at it.
100k is the number usually cited for this. Not sure how that calculation is done, though.
