T. Tappman Tappman is a naïve Anabaptist minister from Kenosha, Wisconsin , who is tormented throughout the novel by his rude, manipulative atheist assistant, Corporal Whitcomb. Easily intimidated by the cruelty of others, the chaplain is a kind, gentle and sensitive man who worries constantly about his wife and children at home. ● Colonel Cathcart Further information: Colonel Cathcart A full colonel, Chuck Cathcart is a group commander at the U.S. Army Air Corps base in Pianosa and is obsessed with becoming a general. As such, he does whatever it takes to please his superiors, in particular, by repeatedly raising the number of missions the men have to fly to complete a tour of duty beyond that normally required by other outfits. This becomes the bane of Yossarian's life, as every time he comes close to obtaining the target number of missions for being sent home, Colonel Cathcart raises the number again. ● Doctor Daneeka Further information: Doc Daneeka Dr. Dan Daneeka is the squadron flight surgeon and a friend of the novel's protagonist, Yossarian. Doc Daneeka's main motivation is for his own welfare, whether that be making money or protecting his own life. He generally forgets his moral duty as a physician except in the most extreme of circumstances. Doc Daneeka feels the military is responsible for him being drafted into the war effort and putting him in harm's way, because they were distrustful of him when he lied on his drafting papers about his health. He is constantly scared of upsetting his superiors who may see fit to then ship him off to the far more dangerous South Pacific. Already he sees it as military cruelty to have been assigned to the Air Corps even though he is scared of flying. ● Milo Minderbinder Further information: Milo Minderbinder First Lieutenant Milo Minderbinder is the mess officer at the U.S. Army Air Corps base and he becomes obsessed with expanding mess operations and trading goods for the profits of the syndicate (in which he and everyone else "has a share"). Milo is a satire of the modern businessman, and beyond that is the living representation of capitalism , as he has no allegiance to any country, person or principle unless it pays him and profit is generated. Milo even begins contracting missions for the Germans, fighting on both sides in the battle at Orvieto and bombing his own squadron.
