The Custer Memorial consists of a bronze statue at the site of George Armstrong Custer's birth, the foundation of the house in which he was born, and an exhibit pavilion. George Custer (1839–1876), known as a daring cavalry brigade commander of the Civil War, and his division blocked General Robert E. Lee's retreat during the Appomattox Campaign. Post Civil War, within the army, Custer was defeated and killed in the Indian War's Battle of Little Bighorn (1876) by a Native American coalition (primarily Sioux, Cheyenne, and Arapaho) led by the Sioux Crazy Horse, Gall, and Sitting Bull.

The memorial offers an exhibit pavilion.

The Fort Laramie National Historic Site commemorates Fort Laramie. Originally constructed in 1841 as a privately owned fur trade fort, the settlement was known as Fort John. It acquired its new name in 1849, after the U.S. Army purchased the outpost in order to protect travelers on the Oregon Trail from the local Native American populations. The United States and the Plains Indians honored the Treaty of 1851, which demanded peace from both parties, for only three years. During the 1860s, fort soldiers were primarily concerned with maintaining nearby telegraph wires. Collections include 19th-century frontier artifacts.

The fort offers an 18-minute introductory film, exhibits, Junior Ranger activities, and an audio tour for rental. The audio tour includes narration, readings from primary source documents, and soundscapes. The website offers a virtual tour.

From Crazy Horse to the cavalry to the K-9 Corps, Fort Robinson played host to them all. Visitors to the site can experience the long and varied history of this outpost on the Plains. The museum at Fort Robinson is located in the 1905 post headquarters building. Museum exhibits trace the history from the post's role guarding the Red Cloud Agency (1874–77) through the housing of World War II German POWs (1943–46). Among the many fascinating objects in the museum's exhibits are the only known dog kennel from the K-9 Corps of World War II; marksmanship medals earned by Caleb Benson, a Buffalo Soldier at Fort Robinson between 1902 and 1909; and 19th-century Sioux objects related to the Red Cloud Agency. Visitors can explore more than a dozen historic structures and sites such as the 1904 blacksmith shop, the 1908 veterinary hospital, the 1887 officers' quarters, the 1875 guardhouse and adjutant's office, and the old post cemetery.

This site preserves a military post built in 1867 and used continuously as a military reservation until 1890 when it became a boarding school for Indian children. The brick buildings, which replaced an earlier log fort, appear much as they did when built of locally made brick in 1868. Original buildings are now being used to house museum exhibits. Fort Totten served American Indian policy from 1867 to 1959. Constructed as a military post, it became an Indian boarding school, Indian health care facility, and a reservation school.

The site offers a short film, exhibits, tours, and occasional recreational and educational events.

The Fort Assinniboine Historic Site preserves the site of what was once the largest military fort west of the Mississippi River, with 104 structures over 700,000 acres. Founded in 1879, the soldiers of Fort Assinniboine protected settlers from Sitting Bull's Lakota Sioux and other Native Americans. Other responsibilities included patrolling the U.S.-Canada border and preventing the Blackfoot Confederacy, Montana Indian Reservations, and Canadian Native Americans from acting against Euro-American settlers. The fort's location was selected as the nexus of several Native American trails. The site currently serves as an agricultural research center.

The site offers guided tours. Reservations are required for groups.

Known historically as "the Gateway to the Dakotas," Fort Abercrombie was the first permanent United States military fort established in what was to become North Dakota. It was also the only post in the area to be besieged by Dakota (Sioux) warriors for more than six weeks during the Dakota Conflict of 1862. During the Dakota Conflict, Minnesota Volunteer soldiers manned the fort when area settlers sought shelter there. The "regular" U.S. Army soldiers had been withdrawn during the Civil War and had been replaced by the Minnesota Volunteer Infantry. The fort was not protected by blockhouses or a palisade during the seige, but these defensive structures were constructed soon afterward. The fort guarded the oxcart trails of the later fur trade era, military supply wagon trains, stagecoach routes, and steamboat traffic on the Red River. It also was a supply base for two major gold-seeking expeditions across Dakota into Montana. Fort Abercrombie served as a hub for several major transportation routes through the northern plains.
