Caasi,
The recruiter will likely not be super transparent with the cons side of enlisted life, especially as a crew chief. It’s a hard job, but a fun one. I did it for 7 years as USAF active duty.
Here’s what I will also give as advice: Do NOT share your goals to fly with for your unit until you have given them a few good months of hard work. I have seen time and time again that aircraft maintenance will absolutely bury you under the hangar if they feel like you are “using” them as a way to get into ops. Give them a few good months of high performance then open up about your desire to fly. Once you have a good reputation, people will move mountains for you.
Hit me up if you have more questions/concerns about enlisted crew chief life.
