MADISON CO., Ind. (WISH) — Surviving members of a highly decorated Vietnam War unit on Monday said group recognition for their service is long overdue.

Company D, 151st Infantry, was an Indiana National Guard unit that deployed to Vietnam at the end of 1968. It was the only National Guard combat unit to deploy as an intact Guard unit during the entire conflict. Unusually for a Guard unit, it had received Airborne and Ranger training. D Company became known as the Indiana Rangers.

Donnie Holland, a member of the unit, said they deployed in five-man teams deep in the jungle, sometimes behind enemy lines. They intercepted supplies and Viet Cong coming down the Ho Chi Minh Trail into South Vietnam.
