Soldier
Individuals may also enlist for part-time duty in the Army Reserve or National Guard. Depending on need or fitness to serve, soldiers usually may reenlist for another term, possibly receiving monetary or other incentives.
In the U.S. Army, career soldiers who have served for at least 20 years are eligible to draw on a retirement pension. The size of the pension as a percentage of the soldier's salary usually increases with the length of time served on active duty.

In media and popular culture: Since the earliest recorded history, soldiers and warfare have been depicted in countless works, including songs, folk tales, stories, memoirs, biographies, novels and other narrative fiction, drama, films, and more recently television and video, comic books, graphic novels, and games. Often these portrayals have emphasized the heroic qualities of soldiers in war, but at times have emphasized war's inherent dangers, confusions, and trauma and their effect on individual soldiers and others.
