CHEYENNE (AP) - Seven Navy reservists from Wyoming, Colorado and Nebraska arrived in Cheyenne this week as part of a call-up to support Operation Noble Eagle.

The operation is part of homeland defense efforts.

The reservists met at the Wyoming Naval Reserve Center to finalize travel plans. They also received shots and physicals.

"When you're in the reserves, that's what the job is, to be ready to be mobilized at any moment," said Petty Officer 2nd Class Clayton Steckel.

The Mobile Inshore Undersea Warfare Unit 103 Detachment Cheyenne will report to San Diego for training before going overseas, though they could not disclose their ultimate destination.

Steckel said the reservists would support those on active duty. More reservists will eventually be called, but he said he doesn't know how many or when.

Petty Officer 1st Class Henry Gustafson said there were rumors he would be mobilized two months ago, but he didn't learn anything definite until Friday.

"Since 9/11, we've been kind of expecting it," he said.

His wife, Teresa, said the family is prepared.

"We're just looking forward to getting him back," she said.

Chief Petty Officer Steve Melia said when he received official notification Friday, he was told he would be gone for about one year. Since he'll be gone for Christmas, his family celebrated the holiday Saturday.

He had mixed feelings about getting called during the holiday season but said going overseas means relieving someone else who would have a chance to make it home.

"I'm impressed with the motivation and the readiness of the unit that is being mobilized," said Lt. Cmdr. Sean Brogan, the Naval Reserve Center's commanding officer. "And everybody's attitude is like that. They know they're going to be mobilized some time, and they know when they do get mobilized, it's their turn."
