We can do so much more together than the other way.  

I served with many soldiers over a 20-year period.  In barracks, the racial differences sometimes got a little crazy during that time frame.  

Mostly, though,  it was about as serious as references to Micks, Polacks, Squareheads, Honkies, Red Necks, Poor White Trash, New Yoricans,  'Doing the Dozens' and such.  

18-20+-something kids are not too 'politically correct'!   Particularly not the enlisted ones.  

When it was important, however, it got closer to 'The Band of Brothers" thing.  

"I don't care what race PFC Washington is; he is one of us and you do not get to 'F.....k with him!"  "Not unless you want to take on the rest of us!"

And the band played on while the issue was resolved.  Almost no one had to go the medics.....usually!
