Thanks, Larry, I appreciate that (and it's nice to know someone's reading the thing).
My layout concept is for a light Army participation on a 3-foot line in the South during WW2. The only Army rolling stock will be a Whitcomb switcher (a Backwoods miniatures kit which drove me nuts trying to build it, 'drop right onto the frame' my eye, you have to re-engineer the entire kit and the donor running gear to make it fit together!) and a single Army-marked boxcar. I had an extra Bachmann box lying around and I decided to make Army decals for it from blank decal stock. I made the build date from WW1 and painted it grey (a common color back then for the Army) with the instruction block of, "when empty, return to Army control - Camp Eustis, Virginia". I didn't want to go nuts and have all-Army trains, tempting as that is. I'll have some Jeeps on flatcars and 55-gallon drum and jerry can loads for some gons, stuff like that. I also have a couple of dozen GI figures all painted up, including several who will be huddled around a card game behind a depot.
I 'play' with 1:1 scale Army stuff often, but all WW2 now. I had fun with 'army stuff' on active duty when I was an officer in the late 90s-early 2000s...
This weekend, I'll be displaying stuff at a local airshow, my WW2 display group always puts on a good show there:
