It may be a little late for MTW/VI, but once the criteria and format are established, they could be easily adapted for RTW and beyond.

What am I talking about?

Unit Flash Cards.

The backs could have a horizontal screen shot of the default size unit in the field. On the front, the unit name, icon and specs, including costs of upgrades. There could be by faction-by era availability deck sets, which I think would be most useful, or an all on one card for each unit type.

The object is to provide a fast way to learn to identify units at a glance, to help memorize unit types and specifications, and a tool to help in making troop purchase decisions.

Anyone interested in development of this tool, please post below.

Or if you would just like to have a set, if and when they are finished, please post also.
