For DefaultUnitType, is this just the basis for comparison for other units within that table?

<GameData>
    <Table name="UnitCombatInfosEx">
        <Column name="CombatClass" type="text" reference="UnitCombatInfos(Type)" default="NULL"/>
        <Column name="DefaultUnitType" type="text" reference="Units(Type)"/>
        <Column name="IsDefault" type="boolean" default="false"/>
    </Table>

The display for recon units is broken so I am hoping that UNIT_PATHFINDER as initial default would fix. What is the XML looking for?

    <UnitCombatInfosEx>
        <Row>
            <CombatClass>UNITCOMBAT_RECON</CombatClass>
            <DefaultUnitType>UNIT_SCOUT</DefaultUnitType>
        </Row>
