* Generally Required: A high school diploma or GED is the *standard* requirement. This demonstrates a basic level of education and maturity needed for the rigors of military training.
* Specific Programs: Some programs might have higher education requirements, demanding an associate's degree or even a bachelor's degree. These are usually for more specialized roles.
* Waivers: In rare cases, waivers might be granted for individuals who don't meet the standard educational requirements, but this is uncommon and depends on various factors including demonstrated skills and experience.
In short, while not impossible to join without a high school diploma, it's highly unlikely. Having a high school diploma or GED significantly increases your chances of acceptance.
