Chances are, the greeting, "It's Lt. Dan!" was heard more than a few times on the Naval Academy grounds this week.

Actor Gary Sinise, Oscar-nominated for playing the irascible Lt. Dan in "Forrest Gump" and -- more pertintently here -- a steadfast supporter of the U.S. armed forces, paid a visit to the U.S. Naval Academy Thursday.

While in Annapolis, Sinise toured the academy grounds and met with academy leadership, including the superintendent, Vice Admiral Michael H. Miller, and Commandant of Midshipmen Captain William Byrne, said USNA spokeswoman Judy Campbell.

Proof of Sinse's visit can be found here, on the USNA's Facebook site, where a gaggle of Sinise-touring-the-academy photos have been posted.

Sinise, who stars in CBS's "CSI: New York," does extensive work with the USO. He has also hosted the annual Memorial Day concert from Washington, D.C.
