After enjoying years of the Air Force dominating the skies in the fight against the Islamic militants in Afghanistan, Iraq, and Syria, the Army is beefing up its short-range missile-defense capabilities to counter the rockets, missiles, and weaponized drones that are increasingly becoming staples of foreign arsenals. And while the return of active-duty maneuver SHORAD battalions for the first time since the end of the Cold War is part of Chief of Staff Gen. Mark A. Milley’s strategic emphasis on a “combined arms, multi-domain capable” Army, the tactical implications are far more appealing: a bunch of new, explosive toys to play with.
