The latest Utahns activated in the military reserves are 24 firefighters of the 419th Tactical Fighter Wing, stationed at Hill Air Force Base.

They were called up Thursday in support of Operation Desert Shield. "They will remain at Hill AFB on active duty," said Capt. Tess Cowan, spokeswoman for the 419th.Ten of them have been working at Hill in a volunteer status since August. The firefighters are from Utah and Idaho.

They are assigned to the 419th Civil Engineering Squadron, a 192-person unit.

Cowan said another of the tactical fighter wing's units at Luke Air Force Base, Ariz., also recalled 24 firefighters.

The call-up came on the heels of an announcement by the Pentagon Monday that Defense Secretary Dick Cheney increased by 63,000 the maximum number of reservists who can be ordered to active duty. The new limit is 188,000.

In early November the overall ceiling was 50,000.
