Lowest rated episode of the series as of September 2021
The soldier zombie that Daryl kills is wearing an M81 woodland BDU, which was retired by the U.S. Army in April 2008. This means that either the soldier has been dead for many years, or that he's wearing old clothes.
When Daryl is about to put the first MRE food he found off the Soldier, he stops for a moment and says "Nice!". Probably a nod to the Youtuber Steve1989MREInfo that reviews MRE and food rations from 1963 to current dates since 2015, famous for saying "Nice!" in his reviews.
