A spectacular collection of military artifacts is housed at the 45th Infantry Division Museum in Oklahoma City. Exhibits in the museum present these fascinating objects to narrate the military history of Oklahoma's own 45th Infantry Division of the National Guard, also known as the Thunderbirds. The museum highlights other aspects of American military history as well. Outside on the grounds of the 45th Infantry Division Museum is Thunderbird Park. Some of the larger artifacts of Oklahoma's military history are located there, including tanks, aircraft and large guns.
