Info Request

[choppinlt]

It has been over a week and things are progressing fine. While we wait for something to actually "see", I have a request. I am always trying to find good sources for various orders of battle. I have found lots of good sources for division level and down, however I have found little discussing Corps level and Army level for American, British and Commonwealth forces. Does anyone have access to any of this information? I am looking for a complete OOB, but at a minimum I would like to know transport, engineer, artillery, or any independent combat unit assigned at these levels.  Thank you in advance for any information you can share.
