AppleTv alerted me of their acquisition of the WW2 Atlantic convoy movie Greyhound and I had time so I watched it. It was pretty good, especially considering none of it was shot at sea, the computer graphics were that realistic.
Then it was on to a documentary on armored tanks, called just Tanks, a history from Britain’s “Mother” in WW1 to the new Russian T-14. I noted that many German and Russian tanks were built to protect (as much as possible) the crew of three or four. American tanks of the 40s through the 60s were not. Something I learned back in 68-69 as a second lieutenant of Armor, the tanks.
