http://www.slate.com/id/2111432/Soldiers have long been subjected to invidious generational comparison. It's a military rite of passage for new recruits to hear from old hands that everything from boot camp to combat was tougher before they arrived. The late '90s coronation of the "Greatest Generation"—which left many Korean War and Vietnam War veterans scratching their heads—is only the most visible cultural example.
Generational contrasts are implicit today when casualties in Iraq are referred to as light, either on their own or in comparison to Vietnam. The Center for Strategic and Budgetary Assessments, for example, last July downplayed the intensity of the Iraq war on this basis, arguing that "it would take over 73 years for U.S. forces to incur the level of combat deaths suffered in the Vietnam war."
But a comparative analysis of U.S. casualty statistics from Iraq tells a different story. After factoring in medical, doctrinal, and technological improvements, infantry duty in Iraq circa 2004 comes out just as intense as infantry duty in Vietnam circa 1966—and in some cases more lethal. Even discrete engagements, such as the battle of Hue City in 1968 and the battles for Fallujah in 2004, tell a similar tale: Today's grunts are patrolling a battlefield every bit as deadly as the crucible their fathers faced in Southeast Asia.
Economists like to quote statistics in "constant dollars," where they factor in historical inflation rates to produce statistics that allow for side-by-side comparison. Warfare is more complex than macroeconomics, but it is possible to produce a similar "apples to apples" comparison for casualties across conflicts. In a recent article for the New England Journal of Medicine, Atul Gawande (a former Slate contributor) concluded that improvements to military medicine since Vietnam have dramatically reduced the rate at which U.S. troops die of wounds sustained in combat. The argument follows a 2002 study that tied improvements in U.S. civilian trauma medicine to the nation's declining murder rate. While firearm assaults in the United States were rising, the murder rate was falling, largely because penetration wounds that proved fatal 30 years ago were now survivable. Thus, today's murder rate was artificially depressed in comparison to the 1960s.
