If it was to shroud an area, then it would be a Mobile Gap Generator...
And also, I've found that a mobile gap generator would be more of a liability than an asset (If you see a mysterious amount of shroud moving then common sense would make it an army going under cover, so you attack that instead of simply moving one's army around the map searching in vain.)
