Army frontline air defenses ended decades of neglect this week when it delivered the first four operational Stryker anti-aircraft vehicles to Germany. The Maneuver Short-Range Air Defense (MSHORAD) Strykers are armored 8×8 vehicles fitted with an autocannon and a missile launcher capable of firing Hellfires or Stingers. They will replace the less well-armed, less mobile, and more vulnerable Avengers, a 1980s-vintage variant of the 4×4 Humvee that can only fire Stingers.
