Cheyenne C. Willey, 36
Willey was with his sister in the delivery room when she gave birth to her younger daughter, buoying her spirits with characteristic humor. "He kept saying, 'It's OK, I'm not looking,' " she said, laughing at the memory. "But he was there for me the whole time." His family had a tradition of military service and after Sept. 11, the pull of military service became almost irresistible.
