Here's what's on the radar in military life this week. Navy Secretary John Fallon is out effective immediately. His departure comes during a high-stakes moment with U.S. naval forces actively operating amid tensions with Iran. Taking over, at least for now, is Undersecretary Hung Kao, a retired Navy combat veteran. It's the latest in a series of leadership shake-ups across the Pentagon. Annual flu shots are no longer mandatory for service members. Under new guidance, the vaccine is now voluntary for active-duty reserves and civilian personnel. Leaders say it's about personal choice, but the move is already raising concerns about force health, readiness and the potential for outbreaks in close military environments. Meanwhile, a new executive order from President Trump is fast-tracking research into psychedelic therapies for veterans with PTSD. Backed by $50 million, it aims to study treatments like ibogaine, offering potential hope for those who have not found relief elsewhere. But concerns remain around safety regulation and long-term effects. The Pentagon has upgraded Valor Awards for Marines who stood guard at Abbey Gate during the 2021 Kabul attack. Officials say earlier awards didn't fully reflect the extreme risk they faced and the lives they helped save. For many, it's long-overdue recognition. And over on Veteran Life, apparently we all still feel the need for speed. Top Gun is headed back to theaters for a limited time to celebrate its 40th anniversary. And it's not over yet. Top Gun III officially in development. Maverick may end up being the oldest aviator in the history of the Navy. That's your briefing. Make sure you follow along so you never miss what's on the radar.
