Specialist Hall’s lawsuit is the latest incident to raise questions about the military’s religion guidelines. In 2005, the Air Force issued new regulations in response to complaints from cadets at the Air Force Academy that evangelical Christian officers used their positions to proselytize. In general, the armed forces have regulations, Ms. Lainez said, that respect “the rights of others to their own religious beliefs, including the right to hold no beliefs.”

“They don’t trust you because they think you are unreliable and might break, since you don’t have God to rely on,” Specialist Hall said of those who proselytize in the military. “The message is, ‘It’s a Christian nation, and you need to recognize that.’ ”

Major Welborn declined to comment beyond saying, “I’d love to tell my side of the story because it’s such a false story.”

But Timothy Feary, the other soldier at the meeting, said in an e-mail message: “Jeremy is telling the truth. I was there and witnessed everything.”
