Let's roll through Korb and Ogden's argument.
"In July an official report revealed that two-thirds of the active U.S. Army was classified as ‘not ready for combat.' When one combines this news with the fact that roughly one-third of the active Army is deployed (and thus presumably ready for combat), the math is simple but the answer alarming: The active Army has close to zero combat-ready brigades in reserve."
This is all true, but is not quite as meaningful as Korb and Ogden suggest. The Army is clearly strained and the fall-off in readiness is alarming. The result is that most Army brigades are not rated "ready" - a complex metric that includes troop strength, equipment levels, and so on - until right before they deploy. In particular, units that have just rotated out of Iraq this summer are inevitably rated "not ready." But that is not to say that no brigades could be gotten ready fairly quickly to go to Iraq or elsewhere.
"The second place to seek new troops and equipment is the Army National Guard and Reserve. But the news here is, if anything, worse."
The National Guard is indeed a mess. But you're not going to pull National Guard brigades for sudden deployment anyway.
"Already, the stress of Iraq and Afghanistan on our soldiers has been significant: Every available active-duty combat brigade has served at least one tour in Iraq or Afghanistan, and many have served two or three."
This speaks to a strain, no doubt. But just because a combat brigade has served once in Iraq or Afghanistan, it doesn't mean that it can't go back. The same is true for brigades that have been there more than once. This is a hardship, but I'm guessing if you asked most soldiers if they'd rather avoid the strain, or win in Iraq, they'd take the strain and the victory. (Which is just one of the reasons why they are so amazing.)
"Thus the simple fact is that the only way for Kristol and Lowry to put their new plan into action anytime soon without resorting to a draft … is by demanding even more from our soldiers by accelerating their training and rotation schedules."
Yes, this is true. And it manifestly is not impossible, so why do Korb and Ogden pretend it is?
"The equipment shortage that the U.S. Army faces at the moment is making it difficult to train troops even at current levels."
Again, this speaks to a strain, and there might not be enough equipment for another 100,000 troops in Iraq, but increases in troop levels short of that can make a difference.
"Increasing the number of deployed troops would compound this readiness problem and leave the Army with little spare capacity to respond to other conflicts around the globe that might demand immediate and urgent action."
