Tip o’ the pileus to Dorothy King for alerting us via twitter that Adrian Goldsworthy had given a lengthy talk in May at the New York Military Affairs Symposium on the topic of Roman warfare. Here’s a link to the audio:
Goldsworthy appears to be the first to talk on something ancient there (or at least in regards to the podcasts that are online), but if you have a hankering for military history, there are a pile of interesting things at Audio Podcasts of Friday Evening Talks.
