This episode continues our Kokoda Campaign Podcast series. This episode looks at Jungle Warfare Doctrine Development, with Dr Adrian Threlfall, an expert in how the Australian Army learned to learn about combat in the jungles of Malaya, Singapore, Papua, New Guinea, and many other islands to the north of Australia. We look at how the soldiers prepared for combat in the Jungle against the Imperial Japanese Army.  What were the barriers to the lessons learnt process?  We look at the British Army and allies in Burma, the Marines on Guadalcanal and the Australian Army in New Guinea. Check out the  show notes for the podcast for all of the information that we cover in this episode as well as the images and other details that didn't make it into the podcast.
