SAG-U Commander's Action Group

from The Spear · host Modern War Institute at West Point

In this episode, Colonel Mike Rosol joins MWI's Charlie Faint to reflect on a career spanning armored warfare, multiple deployments to Iraq and Afghanistan, teaching and scholarship at West Point, interagency work, and his recent service leading the commander’s action group for Security Assistance Group–Ukraine (SAG-U). Mike describes SAG-U’s role in coordinating US and allied support to Ukraine and examines lessons emerging from the Russia-Ukraine war, including Ukraine’s rapid expansion of its military, the transformative role of uncrewed systems, the increasingly compressed relationship between reconnaissance and strike, and the extraordinary speed of technological adaptation on the battlefield. Mike also highlights Ukraine’s willingness to innovate and openly debate how it fights—and warns against the temptation to dismiss the ongoing war's lessons simply because the participants or circumstances differ from those the US military expects to face.
