"You can't beat recruiting here in the Marianas, in Micronesia," said First Sgt. Olympio Magofna, who grew up on Saipan and oversees Pacific recruiting for the Army from his base in Guam. "In the states, they are really hurting," he said. "But over here, I can afford go play golf every other day."   Here, where "America starts its day," the Army recruiting station in Guam has 4 of the Army's top 12 "producers." While small in real terms, enlistments from Guam, Saipan, and American Samoa are the nation's highest per capita. Saipan, with a population of about 60,000 American citizens and green card holders, has 245 soldiers in Iraq.  [American Samoa, population of 67,000, has lost six soldiers in Iraq, most recently Staff Sgt. Frank F. Tiai of Pago Pago on July 17. Guam has lost three. Saipan has lost one.]      "I see yellow ribbons everywhere," Staff Sgt. Levi Suiaunoa said by telephone from the Army recruiting station in Pago Pago, capital of the territory. " 'Come home safely' signs almost litter the streets."   Despite the casualties, poverty and patriotism fuel enlistments.
