Susan Pond: This open lecture delivered by Major General (rtd) Fergus or Gus McLachlan AO FRSN is on the very topical subject of drones, smart munitions and cyber space, the 21st-century defence of Ukraine, and its implications for Australia. Gus tells me he's had a busy day, including just leaving the stage of "The Drum." Gus retired from the Australian Defence Force in 2018. He held several senior appointments in the Army, including responsibility for modernization and strategic planning. He created the first Army cyber capability, introduced reconnaissance drones, and commenced the creation of a deployable digital command-and-control system, in other words, a military Internet of things. Gus's last appointment in the Army was as commander of Land Forces Command, which comprised 36,000 women and men in roles as diverse as helicopter crews, tank and artillery units, logistics and satellite communications.
