ANNISTON (AP) — A defense contractor has notified 139 of its roughly 400 employees at its Anniston Army Depot site that they will be laid off in March and April.

The Anniston Star reported that General Dynamics Land Systems will employ fewer workers after April due to declining military orders for combat vehicles. The company builds and repairs combat vehicles.

Peter Keating, spokesman for General Dynamics Land Systems, said the layoffs were necessary due to a lack of work at the facility.

The layoffs are the latest in a string of cutbacks in Anniston since last year due to the drawdowns of the Iraq and Afghanistan wars. General Dynamics announced 98 layoffs at the depot in November. BAE Systems in December closed its Anniston vehicle upgrade and overhaul facility, laying off 145 people.
