Can be set to 'yes' or 'no' and determines if this object with CanDisguise=yes set disguises permanently as opposed to when it is not moving. This also tells the object to use the unit palette, as opposed to the terrain palette, when displaying its disguise, as it is assumed to tell the game that the object is the Spy, which disguises as another unit. Without this tag, the game assumes the object to be the Mirage Tank, which disguises as a terrain object and hence should use the terrain palette when displaying its disguise,
