*It might be good to cross-list it with "mil", which is more commonly used.  Also, it might be easier to grasp if it were defined in terms of range and size, like 1 yd sideways at 1,000 yds range, or 1 inch sideways at 1,000 inches range.  The key is 1/1000.  Not to be confused with Milly Radiants, which is when a girl named Milly is really cute.
