Exactly. Obama purged many General officers during his reign of terror that didn't agree with his liberal philosophy.
NG troops are not constitutional purist that have been put on by some in this thread. Most don't' even remember taking the oath and they are into it for the education and monthly paycheck.
Kent State in the 70's comes to mind when NG troops opened up with live fire on protesting students,killing some.
As posted in the past, we have had Army Reserve troops on our range for live fire qualification. Some of the new one's have issues figuring out which part of the magazine goes into an AR and which part goes forward. Goes to show what the training level has gone to.
There is also the "Bonus Army" Demonstrations/Riot. General Douglas McArthur ordered an attack on the Bonus Army (Men from WW1 that were promised cash payments and never received **** until they said F*** YOU and marched on Washington)
The Regular Cavalry unit was lead by non other than General Patton (at that time a Major). While in his Memoirs, he stated how much he detested the whole affair, he non the less carried out his orders and charged the demonstrators with sabers drawn. There was also a Company of tanks and 3 Companies of Regular Infantry.
So much for Posse Comitatus....
