The .UNI file holds information about the units.

For each unit record, you will need to retrieve the corresponding class table entry from the class table file in order to interpret the data that follows in that unit record's data buffer in the .UNI file.

After retrieving a unit's classtable entry, read the vuClassData.classInfo[0] value, which will tell you the Domain (air=2, land=3, or sea=4) that this unit belongs to.

Then, check the unit's classtable entry's vuClassData.classInfo[2] value, which will tell you the type of unit:

 Air domain:
   vuClassData.classInfo[2]=1  -- this is a Flight
   vuClassData.classInfo[2]=2  -- this is a Package
   vuClassData.classInfo[2]=3  -- this is a Squadron
 Land domain:
   vuClassData.classInfo[2]=1  -- this is a Battalion
   vuClassData.classInfo[2]=2  -- this is a Brigade
 Sea domain:
   vuClassData.classInfo[2]=1  -- this is a Task Force

Once you know what type of unit it is, you can use the appropriate structure (Flight, Package, Squadron, Battalion, Brigade, or TaskForce) to interpret the data that follows the “unitType”.

Immediately following the data for that unit, is another “UnitType”/Data[] pair. This continues until you have read “NumUnits” records from the file.
