AM General Corp. plans to lay off 250 workers from its Humvee plant in northern Indiana because the U.S. military is buying fewer of the vehicles.

United Auto Workers Local 5 official Don Taber says about 70 workers won't return when the Mishawaka plant reopens from its Christmas shutdown on Jan. 4. He says 180 workers are expected to be laid off during January.

Workers were told last spring that the company might cut jobs if it didn't receive additional orders by year's end.

AM General vice president Carter Hamilton says the plant is assembling 64 of the military vehicles a day, down from its previous 85 vehicles a day.

The company has about 2,300 workers in South Bend and Mishawaka, where it also builds the Hummer H2 consumer truck.
