Nearly every one of our episodes focused on humans' interactions with a particular type of inanimate object on the battlefield, sometimes the way in which the object is wielded by others, sometimes the actions those humans have to take in order to survive the ordeal. It's not just inanimate objects, though, that have found their way into militaries, but animals besides humans that have been used for most everything from hauling weapons to carrying troops to serving as weapons themselves.

In this episode, Staffer and Adin are joined by Hannah Palsa, a PhD student at Kansas State University studying WWII's Dogs for Defense program.
