Hundreds of billions of dollars have been spent arming, supplying and beefing up the U.S. military to fight the wars in Afghanistan and Iraq, and yet the Obama administration feels the need to divert money from “lower-priority” operations to temporarily boost the strength of the Army. Officials in the Defense Department want to shift $1 billion from programs affecting all four branches of the armed services to increase the Army’s size from 547,400 to 562,400 by next year, and eventually to 569,000 beyond that.
