Just read this little ditty at the bottom of the FOX news article about Secretary of the Navy Richard Spencer's resignation??
The Navy has revoked 154 Trident pins since 2011
Found a google-fu saying there are approx 2500 SEALs on active duty with 76 platoons @ 16 each or 1200+ line-studs.
So 154 revokes on a 1200 base 13%+, kinda high??
