This is insight of the characters General Dreedle and General Peckem of the novel Catch-22.

Both characters are the same.
Power hungry, care for no one else but covering their own bums, will do anything to get what they want.
Neither character is mentioned without the other.
They are similar and parallel even though one is casted out.
The twos carelessness to take care of the squadron end up traumatizing Yossarian. And even the other generals add to that trauma.
Moral of the story is, you can be too greedy in life and you can't have everything you want or else we'd all be rich and without war but it isn't bad to strive for a better position for yourself. Just don't overdo it.
Both are impossible char packers to communicate with and are paradoxes. All the generals are paradoxes.

Peckem is a very selfish man trying to constantly get higher in position.
He is a General that was once in special ops but left thinking he'd get ahead in promotions but ends up failing.
He left special operations throwing all his work and sucking up out the window.
He's a fool that tries to make himself sound so sure by using big words that most uneducated men wouldn't get.
He battles with General Dreedle for his position.
He gets Dreedle out of position but the man once under him then took the spot he fought for.
All the generals are the reason why the men are needlessly killed off. Neither of the generals care, they just don't want to look bad.
Peckem's fate was doomed from the beginning by his shady ways. You can only be so greedy in life before Karma gets you.
Heller uses Peckem as an example of how some people in power are and how they'd act.
Peckem is a satirical character but I also believe he could be thematic in a life lesson kind of way.
Peckem is what anyone would thing of a selfish man full of greed. He's careless and sometimes clueless. He thinks so high of himself but the reader would think he's a low down dirty general that cares nothing of the war but more for pretty pictures. The man should've just been a photographer a professional photoshop artist.
"Just pass the work I assign you along to somebody else and trust to luck. We call that delegation of responsibility. Somewhere down near the lowest level of this coordinated organization I run are people who do get the work done when it reaches them, and everything manages to run along smoothly without too much effort on my part. I suppose that's because I am a good executive." (Heller 330)

An old man in charge of Yossarians squadron in Pianosa as Superior Commanding Officer of Pianosa.
General Dreedle is a selfish and just as cocky old man as Peckem. The two mat no each other well yet India out smarted. Sadly it was Dreedle.
Dreedle has a son-in-law Moodus he keeps close and loves to taunt with a hot nurse. Just making sure he doesn't cheat on his little girl.
Constantly Dreedle is getting petty attacks from Peckem and soon is out of position and replaced by Scheiskopff.
Dreedle does his job for the most part but the way he carries them out Is unforgivable. He cares less if a man dies. A man in power only cares if you've done the job and if you've done it right.
I believe Dreedle was removed to represent a point. Yes the more educated get what they want yet the greedy can only go so far.
"You Mean I can't shoot him?" (Heller 221) is the defining sentence of Dreedle's character and shows how heartless and careless he is as a general. Just because Major Danby couldn't synchronize the boys watches and moaned out of place. Dreedke thought he had absolute authority. Scary how he's a general and thought he was God.
