Invisible Battlefields is a podcast meant to engage with the Chemical and Biological defense community and is another platform providing a voice highlighting the continuous collaborations that the DTRA JSTO program explores with industry partners, academia, and other government agencies concerning chemical and biological threats and protecting our Joint Force against them.
