Military records WWII

Hello. I'm trying to cite records scanned and uploaded to the 90th Division Association's website. These are After Action Reports and General Orders at this point. I have microfilm copies of Morning or Daily Reports also which need to be cited. I'm not sure how to cite these.

The General orders are from this part of the website: http://www.90thdivisionassoc.org/afteractionreports/frames/reportsframeunit.htm

The 90th Division was part of the Third Army in WWII.

Any help is appreciated.

Thank you!

Jennifer
