Are you bound to follow illegal orders? No.
This is correct. I have never received deployment orders since obama has been in office. Other orders I’ve received (ie day to day functioning) would have been given regardless of who was in office. All orders I’ve received have been within the battalion and thus I see them as legal orders.
Any order coming from obama would be invalid.
All Command Authority is derived from the commander-in-chief.
Uphold your sacred oath.
