This flag determines how fast vehicles with the subterranean locomotor will travel vertically, i.e. when submerging to or emerging from the ground. Together with the unit's setting, it also affects how fast the unit rotates as it begins to burrow. Higher values indicate faster speed.Note: This flag does not control how fast units move horizontally when underground, nor how fast they rotate when emerging from the ground – the former setting is hardcoded, while the latter is solely controlled by the unit's .
