CAST

Corporal Walter Eugene "Radar" O'Reilly

Corporal Walter Eugene "Radar" O'Reilly comes to the 4077 as a naive farm boy. Fond of animals, he raises several during his tour of duty.

Gifted with seemingly super-human abilities to hear incoming helicopters, he is given the nickname "Radar." Starting out overwhelmed by his role as clerk, he eventually becomes indispensable to the unit, keeping it running like clock-work.

Radar has hero worship for Hawkeye and often conspires with him, Trapper John and later, B.J. Hunnicutt in their daily pranks. Radar's love life often becomes the obsession of his fellow troops. One of Radar's most difficult assignments is delivering the news that his beloved Col. Blake's plane was shot down over the Sea of Japan. He soon becomes close with Col. Potter and gifted him with a mare, "Sophie," that he, Hawkeye and Hunnicutt rescued.

Upon the death of his Uncle Ed, Radar receives a discharge and is sent back home to help run the farm. Leaving a boy, but returning a man, Radar leaves his teddy bear behind.
