In Pocket Casts go to the Discover tab.
Searching by Inside Battlefield or EA or any search term will not work. Instead enter the URL for the Apple iTunes page:
Searching by that URL in Discover should bring up the podcast and allow you to subscribe. Note: this does not work for all iTunes podcasts so I am sure there is more to why it works for this one and not others.
Hope this finds someone in need and solves the same problem I had. Enjoy!
