For a small group of landlocked men, memories make all the difference.

At each monthly meeting of the USS Carbonero Base, the group stands at attention as the base commander tolls a small brass bell while the man next to him reads the fate of sunken submarines lost to the depths in that month of history.

The 23 men range in age from early 30s to mid-80s and share one common link -- they've spent months, sometimes years, on one of the U.S. Navy's military submarines.

"I never served with anybody in here, but they're like brothers to me," said Alan Syler, one of the base founders and current commander of the Chattanooga-based group.

The way Mr. Syler explains it, only other submariners know what the service was like -- the quarters, the missions, the food and the ports are shared memories.

When he and others decided to form the group -- or base, as these organizations are called in the Navy -- Mr. Syler knew there probably were a few hundred former submariners in the area.

Many who served on nuclear submarines found jobs at nuclear plants such as Watts Bar, Sequoyah and Browns Ferry after their time in the Navy, he said.

To form an official base and be recognized by the United States Submarine Veterans Inc., Mr. Sylar had to have eight members and finish a tall stack of paperwork. After about six months, the base held its first meeting on May 11. The USS Carbonero name came from the submarine one member served on during World War II.

Al Smith is the group's unofficial storyteller, an accomplishment among a room full of tellers of sea tales. He served aboard two submarines during World War II, the USS Carbonero and the USS Cochino.

At meetings, most of the base's members wear blue vests adorned with pins, patches and badges, a kind of road map for fellow veterans that tells a detailed history in a flash to the seasoned eye.

Small pins with the Vietnamese flag show that a submariner served during the Vietnam War. Other markings show the job a submariner held or ports visited.

But Mr. Smith's vest is a faded orange with older patches made of a thinner cut of cloth. During a recent base meeting, he pulled out another orange vest, also faded, also full of pins and honors. This was his wife's vest, he tells the group. She died years ago.

But the vest is his way to remind members that the wives support their husbands at sea and after their travels have ended. His display is a shorthand way of reminding the group that they are family.

Larry Paige, vice commander of the base, recounted the thousands of lives lost during America's wars when submarines were sunk. But he also noted the swift victories of those submarines against the Japanese Navy after the Pearl Harbor attacks that crippled most of the U.S. Pacific Fleet.

Mr. Paige served aboard submarines during the Cold War, when the United States patrolled worldwide waters in a deadly game of cat and mouse with the Soviet Union.

"We looked at life in that submarine. It was never the steel that we respected, it was the people we respected," he said.
