They fought together in Vietnam, but recently two veterans groups battled each other over a symbol both respect, the Vietnam wall.
Both have built replicas of the Vietnam Veterans Memorial in Washington. The replicas consist of two walls constructed more than a decade ago by a Michigan group, and replica a Florida group unveiled last year. In the past few months, both groups have fired off volleys of e-mails over a trademark dispute and threatened each other with legal action.

The Michigan-based Vietnam Combat Veterans Limited said Florida's group has used its name, "The Moving Wall," on a commemorative coin and other literature. The Florida group, Vietnam and All Veterans of Brevard, said any use was a mistake and it has stopped selling the coins.
