As the Army's 3rd Infantry Division wages war in southern Afghanistan, some of its soldiers back home at Fort Stewart, Ga., have found themselves in the middle of a different kind of battle.

Months before the Army's ill-fated 5th Stryker Brigade was to leave Washington state in the summer of 2009 for the war in Afghanistan, its commander became convinced that he needed a particular type of equipment to counter cunning bomb-makers.

The Army ordered the destruction of a report that praised the performance of an off-the-shelf software program that finds buried explosives in Afghanistan and replaced it with a revised less-favorable assessment, according to internal Pentagon documents.
