Generals in BDU’s on TV?

[Foosinho]

I understand that the top Army General declared that all soldiers were to wear the field uniform in support of those in the combat zones, sort of a "We're all on the same team." gesture.

I don't know the validity of that; it's just what I've heard.

Correct. I worked at a USAF base for the first half of this decade, and the "uniform of the day" switched from blues to BDUs shortly after we went to war. The official directive from the chain-of-command that it was a bit of a "solidarity" thing with deployed soldiers during a time of war. It would not surprise me if other branches did the same thing.

And, to reinforce what JohnsonK noted, the USN khaki uniform is generally considered a "work" uniform, as opposed to the summer white dress uniform. Similarly, during the winter they've got the dark blue "work" uniforms to offset the black (or is it navy blue?) dress uniforms. The USN apparently has a new digital camo pattern (presumably in ACU cut), but that's a newer development than when I was in USAF ROTC 15 years ago, so I don't really know much about it.

When we did flag details at football and basketball games when I was in ROTC we wore our blues. I noticed at Ohio State's last football game I attended that the cadets were wearing BDUs/ACUs. Even the Navy cadets - they were either wearing MARPAT or the old Woodland (Navy and Marine cadets both drill under the auspices of the Navy, so I'm guessing future Navy officers wore the Woodland pattern, while future Marine officers wore the MARPAT).

Bradley over Eisenhower or Marshall, except that Bradley dressed appropriately to the occasion or local.
Montgomery over Brooke, except that Montgomery dressed appropriately (arguably) to the occasion or local.

I’m not there, but if I were. I think that I might resent non combat-zone field uniform as not much more than General's vanity.
Home HQ's and staff and bases are very important to the mission, but they are what they are and they are where they are.
