Currently there's no command to return the description of a unit (the one from the field in the editor below the unit's initialization-field, that's shown in the role selection screen).
In a lot of cases it'd be great to have such a command, as you could display not only the rank of unit or the player's/unit's name but its description as well. Currently you can only use getText(configFile >> "CfgVehicles" >> typeOf(_x) >> "displayName").

getDescription could do that, but it only gives out an array of the unit's clothing and backpack. Something like getUnitDescription should instead return a string from the unit's description-field or, if not specified, the displayName from CfgVehicles.
