What was your slang name for the generic motivated new guy and/or screw up in each service?

Could you fine ladies and gents please share some of the slang that you can remember about what you called the young motivated boots or the screw ups in your respective services?

In the Marines, I heard "LCpl Schmuckatelli" used for both the motivator as well as the screw up example of "who not to be like" all the time. For you more senior Marines, I believe "Gomer Pyle" was used as mostly derogatory but I didn't hear that as often.

In the Air Force I know they use the name "Airman Snuffy" based on the legend of Maynard Smith.

Not sure about Army, Navy, and Coasties. Could anyone share what their slang names were? Also if you have any additional ones for USMC or USAF, please feel free to speak up.

Looking for names specifically. Not like, for example: "PFC F***stick"

If you need a reason, historical interest, posterity, traditions, etc.
