America's front line of missile defense is straining under the demand of global threats | CNN...

"The US Army’s air defense units are among the most overworked in the US military, manning missile systems across the globe to provide around-the-clock deterrence against adversaries including North Korea, China, Iran and Russia.

In describing the problem to CNN, the Army’s most senior air defense officer, Lt. Gen. Dan Karbler, recounted something an Army sergeant told him recently: “Sir, it’s simple, pure math. We have more missions than we have air defense capability.”

As demands stack up with the war in Ukraine and amid looming concerns over a potential conflict with China, service leaders have been sounding the alarm that these critical missile defense units could be stretched too thin.

“It could get out of whack in a hurry if it’s not managed properly,” Maj. Gen. Brian Gibson, commander of the 94th Army Air and Missile Defense Command in Hawaii, told CNN." [. . .]
