But the Army's Dec. 21 report, drawn from confidential interviews with operators of the vehicle in Iraq in the last quarter of 2004, lists a catalogue of complaints about the vehicle, including design flaws, inoperable gear and maintenance problems that are "getting worse not better." Although many soldiers in the field say they like the vehicle, the Army document, titled "Initial Impressions Report -- Operations in Mosul, Iraq," makes clear that the vehicle's military performance has fallen short.
The internal criticism of the vehicle appears likely to fuel new controversy over the Pentagon's decision in 2003 to deploy the Stryker brigade in Iraq just a few months after the end of major combat operations, before the vehicle had been rigorously tested for use across a full spectrum of combat.
The report states, for example, that an armoring shield installed on Stryker vehicles to protect against unanticipated attacks by Iraqi insurgents using low-tech weapons works against half the grenades used to assault it. The shield, installed at a base in Kuwait, is so heavy that tire pressure must be checked three times daily. Nine tires a day are changed after failing, the report says; the Army told The Post the current figure is "11 tire and wheel assemblies daily."
"The additional weight significantly impacts the handling and performance during the rainy season," says the report, which was prepared for the Center for Army Lessons Learned in Fort Leavenworth, Kan. "Mud appeared to cause strain on the engine, the drive shaft and the differentials," none of which was designed to carry the added armor.

The vehicle's computers are too slow and overheat in desert temperatures or freeze up at critical moments, such as "when large units are moving at high speeds simultaneously" and overwhelm its sensors.
...The main weapon system, a $157,000 grenade launcher, fails to hit targets when the vehicle is moving, contrary to its design, the report states. Its laser designator, zoom, sensors, stabilizer and rotating speed all need redesign; it does not work at night;
