The pictured medal is the U.S. Armed Forces Antarctica Service Medal.  It is NOT a BSA medal and may not be worn on the scouting uniform.  Though a military service medal awarded by the Department of Defense, it is frequently awarded to civilians for research work done for a minimum of 15 consectutive days below 60 degrees south latitude.  The medal is a one-time award, though for serving a full research winter entitles the recipient to a 'wintered over' disc on the ribbon or bar on the medal itself.

The shown square knot is also NOT official BSA issue.  It is an aftermarket production woven on the same looms as BSA knots.  The BSA has said that they will not recognize it as an official knot due to the miniscule number of scouts/scouters that earn it and the high cost of adding such a rare knot to the insignia inventory.

As it is not a BSA knot, no decision has been made in distinguishing between scouts/scouters who earn it through the BSA program, or all other means.
