Johanson victim of which hunt?

TBO.com reports that:  The mother of [Kiel M. Johanson] a Coast Guard chief who is being kicked out of the service over a hazing incident says her son is the victim of a "witch hunt" and is going to appeal his court martial.  I believe the older Navy terms included “pink belly” and “greasing.”  I seem to remember from defending such cases back in the 80’s.
