Poile will be complemented by Ray Shero in the position of associate general manager and Brian Burke, who will be the director of player personnel. Shero is the general manager for Pittsburgh, while Burke is back with Anaheim as a scout after being let go by the Toronto Maple Leafs earlier this year.
"Being chosen for this position is a tremendous honour," Poile said in a statement. "When you get to represent your country, it's a special feeling. I look forward to working with our management team in fulfilling our ultimate goal of bringing home the gold medal."
The 63-year-old Poile has been with Nashville since their inception in the late 1990s, and combined with his time at Washington, has served as an NHL general manager for 31 consecutive years.
USA Hockey will hold a press conference Saturday, at which time they will introduce their coaching staff. The Americans, under the aegis of Burke, settled for silver after a thrilling overtime final at the 2010 Vancouver Games against Canada.
The U.S. also won silver in 2002 at Salt Lake City, but have finished off the podium the two occasions NHL players have participated in Olympics outside of North America.
The NHL hasn't officially secured an agreement with the International Ice Hockey Federation (IIHF) to participate in the Sochi Games, but it is believed to be a formality.
