We've seen images and video from the front lines of war. During that time, sketches and artwork were also used to illustrate conflict. It originated during World War I and continued in Vietnam. That's when a young Minnesotan worked as a combat artist.
In the Army, Les Fordahl spent just over a year embedded with a brigade, capturing daily life on base and during combat. He says most of his combat art is in the Library of Congress.
"I've turned the whole house into my art studio and gallery," Fordahl said.
Fordahl started studying art at age 8. His first commission came just a few years later. That passion for capturing real people and places would follow him into his time in the Army.
"They needed a draftsman for communication systems in Vietnam," Fordahl said.
