Something like 70% of military members only do one contract. Part of that has to do with it sucking at a fundamental level, but undoubtedly culture and objectives play a role in it too. Junior servicemembers are treated like shit by the institution as a matter of course, and they try to gaslight you about it being good training or whatever but it's not it's just bullshit.

And then you get out and learn that all the shit they said about people wanting to hire veterans was bullshit too. Enjoy checking that box on every job application forever and it not making any difference.
