Hey, Dinosaur, if you’re looking for additional piece ideas, there’s a whole world of HO-scale infantry miniatures to work with, just in cheap plastic… for Chinese, for instance, Caesar Miniatures just came out with a set of WW2 Nationalist Chinese infantry that look pretty good. They’re in blue, and I’m no painter, but serendipitously, that’s a color that works for me… since you paint, that probably isn’t a problem for you. For my A&A variants, I often use HO’s from companies like Airfix, Revell, ESCI, etc. for various types of elite units (like German paratroops or British Commandos) or minor nations (like the French, Italians & Chinese). Yeah, I just couldn’t go with using a red Russian for the Chinese, either… I used them for elite Soviet “Red Guards” instead, so they would have an option that could go toe-to-toe with those German “SS Panzergrenadiers” (I sometimes use old-edition gray for standard infantry and new-edition black for those SS troopers).
Anyway, if you’re interested in trying some HO sets and want to save a little research time, I’d be happy to give you some hints on what’s available and where you can find them.
