Good point, Rob: The only vehs in 71 Bty with permanent C/S were the gun tractors, the CP (command post), and, I think, 29's (the Battery Commander's) jeep. Most other vehs were borrowed from the Third Herd (3RCHA) for weekend ex's.
(parentheses added for the jargon impaired!

)
Cheers! Mike
P.S: Rob: amazing work you're doing on the 105mm C1!!! I bow in admiration and jealousy!
