It was 2008 when the Army announced that the last 6,000 M113 varients were being replaced with Bradley and Stryker varients. This is to be done by 2014.
1,026 M113 varients are being provided to the IA under US FMS EDA program [The Iraqis pay shipping and refurbishment]:
66 M1064 120mm Mortar Carriers
68 M113A2 AMEV [Ambulance]
618 M113A2 APC
80 M577 Command Post Vehicles
192 M548 Cargo Carriers
2 M577A2 EMTV [Emergency Medical Treatment Vehicle]
By my accounting we have about 2,900 more M113 varients left to dispose of in the US Army...
Mixed feelings on these. In VN most preferred riding on top of them rather than inside. "Cookers."
