HERLONG, California (CNN) - If you need an example of why it is hard to cut the budget in Washington look no further than this Army depot in the shadow of the Sierra Nevada range.
CNN was allowed rare access to what amounts to a parking lot for more than 2,000 M-1 Abrams tanks. Here, about an hour's drive north of Reno, Nevada, the tanks have been collecting dust in the hot California desert because of a tiff between the Army and Congress.
The U.S. has more than enough combat tanks in the field to meet the nation's defense needs - so there's no sense in making repairs to these now, the Army's chief of staff Gen. Raymond T. Odierno told Congress earlier this year.
If the Pentagon holds off repairing, refurbishing or making new tanks for three years until new technologies are developed, the Army says it can save taxpayers as much as $3 billion.
