Our site houses the most recent Sgt. Shaft columns and all others dating back to 2013. Additionally we have many years of archived Sgt. Shaft columns available at this link. We are in the process of bringing them into this site and format, but it will take some time. There is a gap from 2012 – 2013. We’re working on eliminating that gap and bringing all columns to this site.
Meanwhile, year 2012 – 2013 columns (and more) are available and can be found in the Military.com archive of Sgt. Shaft columns. Their archive is current up until October of 2014.
FRA.org also maintains an archive at this link.
