The Association of the U.S. Army is releasing four new podcast episodes in February, including a podcast focusing on mental fitness and a look at leader development in the Airborne and Ranger Training Brigade.

First up in the “Army Matters” series is an interview with retired Lt. Col. Daniel Johnston, who will discuss the intricacies of the brain and mental fitness. An Army physician and researcher, Johnston co-founded BrainSpan, which works to help practitioners, patients and the public build and sustain healthier and more resilient lives.

The episode is available Feb. 7.

Next up is an episode featuring Command Sgt. Maj. Eric Buonapane, senior enlisted leader of the Airborne and Ranger Training Brigade. During the podcast, available Feb. 14, Buonapane will talk about leader development and leading great teams in the brigade and in the 75th Ranger Regiment.

On Feb. 21, the podcast will feature an interview with Lisa Hallett, executive director and co-founder of Wear Blue: Run to Remember. Hallett, an avid runner, founded the group after her husband, Capt. John Hallett, was killed in August 2009 in Afghanistan. Finding comfort in running, Hallett and the team at Wear Blue work to honor all service members killed in combat and help others heal from the challenges of war.

During the podcast, Hallett will talk about what Wear Blue has accomplished and discuss how setting goals, tangible accomplishments and staying healthy can help someone navigate military life.

Finally, on Feb. 28, the podcast will feature Robert Child, author of Immortal Valor: The Black Medal of Honor Winners Of World War II.

In his latest book, Child highlights seven African American soldiers who were awarded the Medal of Honor, the nation’s highest award for valor, for their actions during World War II after a 50-year campaign to deny them the proper recognition.

A military history writer, director and published author, Child has been recognized with more than 26 writing and directing awards.
