thanks for the TO&E's microgeorge and GHQ. They were instantly useful!
I see a number of 'stand units with "*" after them but no note at the bottom of the page explaining why it's there. For example look at the Germ. Inf. Battalion '42. Some of the transport units like limbers and trucks have an asterisk and some don't. Why?
In other organizations, there are marks after the unit name (like tank platoon*) and there are explanations of this at the bottom of the page so those are clear.
I found the answer to my own question. On other organization pages, the asterisk after the transports means they are optional. the page I was looking at must not have had that note added. Mistakes happen, no worries.
