More than $725 million was spent by the Army on a high-tech network for tracking supplies and expenses that failed to comply with federal financial reporting rules meant to allow auditors to track spending, according to an inspector general’s report issued Wednesday.

The Global Combat Support System-Army, a logistical support system meant to track supplies, spare parts and other equipment, was launched in 1997. In 2003, the program switched from custom software to a web-based commercial software system.
