An Order of Battle normally shows the organization of a higher organization with subunits attached. Commanders names, when known, are commonly included, but detailed information about the units equipment is normally not.
Not all OOB's include both sides forces or even the entire organization from the top to the bottom. It could be an OOB for an entire Army Group or just that of a platoon. Normally OOB's don't go down to squad level but if they are broken down into fireteams they can be shown as well.
At times the overall equipment type may be shown for the unit as well. There can also be information about deployments and if the entire unit was deployed or not. This information may or may not be included in an OOB.
An example of a common OOB is the one for Operation Bagration in June 1944:
