I am no great fan of the Army’s M1126 Stryker infantry combat vehicle (ICV), the eight-wheeled battle taxi hastily adopted by the Army in 2001 to provide an air-transportable vehicle offering more protection and carrying capacity than a HMMWV. It’s too big (at 23 feet long and 9 feet wide, it’s the size of a bus) and too heavy (about 20 tons in fighting trim) to fit comfortably on a C-130 Hercules transport plane or to be dropped by parachute. Its cross-country mobility leaves something to be desired. It is under gunned, normally armed with either a .50-caliber machine gun or a 40mm grenade launcher (the Mobile Gun System, a fire support version armed with an auto-loading 105mm cannon has run into a host of technical problems). And, at something more than $2 million per copy, it is grossly overpriced for the mission it is supposed to accomplish–carrying nine infantrymen across the battlefield in the face of small arms and artillery fire to a place where they can dismount and fight on foot.

But I had not heard any complaints about the Stryker’s armor protection or survivability during the five years it has been deployed in Iraq. With ceramic appliqué armor fitted over a 6-8mm high hard steel shell, the Stryker can resist hits from 14.5mm armor piercing rounds and high velocity artillery fragments. Its armor can be penetrated by the shaped charge warheads of rocket propelled grenades (RPGs), but the bulky, heavy slat armor normally fitted to the vehicle is generally quite effective at defeating that threat (in Iraq, one Stryker was hit by no fewer than nine RPGs in the course of one patrol, but was able to continue back to base under its own power, the crew suffering only minor injuries).
