During my time at the White House Situation Room, it was normal practice for military officers to wear the more formal service uniforms when attending meetings there. They never would wear their less formal combat uniforms. /1
A search for images of Chm of the Joint Chiefs of Staff GEN Milley at the White House would suggest that this tradition continues today. /2 
That makes it even more unusual, but more importantly INTENTIONAL, that GEN Milley wore his Army Combat Uniform to the White House today, as seen in pictures of him accompanying @realDonaldTrump on his St John's Church photo-op today. /3
Am I making too much of this? I welcome comments from my military colleagues. /4
