Welcome! If you haven’t seen it yet you might be interested in my YouTube tribute to the 287th. I pasted it together from still photos when the 287th was reactivated to go to Baghdad with the Big Red 1. You can find it by searching in the YouTube search field for “Berlin 1969 – Part 1”
There are further Parts 2a, 2b, 3, 4, 5, 6. Each is about ten minutes long and is about a particular aspect.
