If you don't know this with a jagdwagen the driver and a hunter making a coach tour until they see game. the coach drive by close as possible to the game and the hunter dismount when near the animal.if made with some skill the coach will have the full attention of the game and it will not notice the hunter who can shoot after the coach leave. you need a horse that don't become shy by the gunshoot, of course.
