Chaplain (Captain) Albert Taylor Tappman

The squadron's nice but ineffectual chaplain. He is kind and weak-willed, but he firmly believes in trying to save human life, particularly Yossarian's. The chaplain enjoys his isolation in the woods despite the black presence of his assistant and his questions about God, life, and creationism. Outside of his little world, though, problems arise. He appeals hopelessly to Major Major and Colonel Cathcart to stop the ongoing increase of required missions. He is also wrongfully interrogated about absurd incidents such as the theft of a plum tomato and Colonel Cathcart's insincere condolence letters.

Corporal (later Sergeant) Whitcomb

The atheistic chaplain's assistant. He tries to make his superior's life as miserable as possible by criticizing him and taking over his operations. Unfortunately, the chaplain is too weak-willed to oppose him, and eventually Whitcomb reports the chaplain's various misdemeanors to Colonel Cathcart in an attempt to gain power and authority for himself.

Dunbar

Yossarian's wardmate, who enjoys shooting skeet to kill time. He tells Yossarian about his strange dreams, which Yossarian passes on to the ward psychiatrist. After realizing that the soldier in white is empty, he is " disappeared" by the doctors.

Captain Aardvark

Nicknamed Aarfy, a constant nuisance in the cockpit. He pretends to be friends with Nately in an attempt to endear himself to Nately's rich father. He is always persuading " nice girls" not to sell their bodies, much to the anger of Yossarian and the other men. Brainless and senseless, Yossarian resents seeing him and constantly punches him when they are together in the cockpit.

Nately

One of Yossarian's co-pilots. He falls in love with a whore he meets in Rome while staying at a specially rented apartment. Nately pursues her to no avail until one night when he and his friends rescue her. After a good night's sleep, she awakens and falls in love with him, too. Unfortunately, Colonel Cathcart threatens to send Nately home without the whore unless he continues to fly more missions. Nately is killed just after he tells Yossarian that he will probably manage to survive after flying so many missions.

Admiral Kid Sampson

One of Yossarian's crew members. He turns around the plane when Yossarian claims that he cannot hear him. Later, he is sliced in half by McWatt when the latter flies his plane just a few inches above the water.

McWatt

Yossarian's pilot. He enjoys infuriating Yossarian by flying his airplane just a few inches over Yossarian's tent. Once, during combat practice, Yossarian loses his temper with McWatt and threatens to choke him to death. McWatt becomes frightened and realizes that Yossarian is indeed going insane. One day, McWatt is flying just above the beach water, and he accidentally slices Kid Sampson in half. Immediately after this, McWatt crashes into the side of the mountain and dies.
