Colonel Cathcart

A ruthless, cold-blooded, ambitious officer. His goal in life is to become a general. He is determined to get attention for himself, and he continuously raises the number of missions that the men must fly to obtain leave. In the end, he makes a dirty deal with Yossarian to try to cover up his illegal number of missions.

Major Major

A shy, awkward boy misnamed by his cruel father. This Henry Fonda lookalike is promoted by Colonel Cathcart to squadron commander and is banished away to a trailer where he is forced to sign piles of useless papers. Eventually, he pretends to be " Washington Irving" and pits the two C.I.D. men against each other for his own amusement.

Sergeant Towser

Major Major's assistant.

Captain Black

Another cold-blooded officer. He starts the Glorious Loyalty Crusade to get back at Major Major. Eventually, his idol, Major -- de Coverley puts an end to such foolishness.

Colonel Korn

Colonel Cathcart's competitor and sometimes sidekick. He is just as cruel as Colonel Cathcart, although he is more inclined to admit to his stupidity sooner. He also joins Colonel Cathcart in trying to coerce Yossarian into making the dirty deal to cover up the illegal number of missions.

Nurse Cramer

A puritanical nurse who diligently cleans the soldier in white. Yossarian suspects that she killed the soldier in white because she is the one who discovers that he has died. She is a good friend of Nurse Duckett, but she strongly disapproves of Nurse Duckett's love affair with Yossarian.

Nurse Duckett

One of the nurses in the ward who is a good friend of Nurse Cramer. She despises Yossarian at first, but later, she pursues a passionate fling with him. She enjoys flirting with the other men, but she eventually leaves Yossarian for a doctor.

The Soldier in White

A soldier encased entirely in white bandages. He is attached to two zinc jars, one to feed him and one to collect his waste. When the latter is full, the jars are switched. Both Nurses Cramer and Duckett vigilantly watch over him. Nobody talks to him except the overfriendly Texan, and the soldier in white never replies. When he dies, Yossarian suspects both the Texan and Nurse Cramer of murdering him. He reappears a second time, much to everyone's alarm, and when Dunbar claims that no one is inside, the doctors " disappear" him.

Giuseppe

The soldier who sees everything twice. Yossarian imitates him to avoid leaving the ward. After he dies, Yossarian impersonates him.
