Which branch of the US military has the most difficult basic training?

I've been researching the military as a possible path after graduation, but it seems like the intensity of basic training varies per branch. In terms of physical and mental challenge, which branch's basic training is considered the toughest?

Determining which branch of the military has the most difficult basic training can be somewhat subjective, as it depends on individual strengths and areas of focus. Nonetheless, many potential military recruits and veterans often point to the United States Marine Corps as having the most challenging basic training regimen.

Marine Corps Basic Combat Training—commonly known as boot camp—is known for its rigorous 13-week program. The training includes rigorous physical conditioning, combat water survival, marksmanship training, and various field training exercises. It also emphasizes core values, team building, and leadership skills. The Crucible, a grueling 54-hour test of a recruit's physical, mental, and moral fortitude where recruits are deprived of sleep and given limited nourishment, is a defining part of Marine Corps training.

That said, each branch's training programs are designed to equip its members with the skills, knowledge, and mental resilience necessary to fulfill their particular roles in the military service. For instance, Navy SEALs on the Special Operations side have incredibly demanding training too. Keep in mind that all this information is to give you an idea – it would be best to speak with a recruiter to get a more detailed idea of what to expect. It's an important decision, and you should take the time and effort to consider your options thoroughly.
