I have uploaded a new version of DB-AWI to Google Documents (see the link above). Lots of changes, such as:
1. A Commander is now more like a DBA LH (Gen) element, rather than a DBN Commander.
2. Changing a lot of the terms, names, and acronyms.
3. Mounted Infantry and dismounting!
4. Light Cavalry push through and retreat.
5. Defining victory conditions.
Still to do (which I am trying out in my current game):
1. Changing the element's order (to and from Close to Loose, and to and from Loose to Open).
2. Scenarios (currently playing Videau's Bridge).
3. Army Lists.
Check out the new rules and tell me what you think.
