Making Recruiting Great Again
According to Wikipedia (not sure if that is the most trustworthy source. Hence, my questions here), a prospective SEAL must first attend 8 weeks of Naval Special Warfare Preparatory School in Great Lakes, Illinois (it's not clear from the entry if this prep school is applicable to officers/usna grads), then 24 weeks of BUD/S, and the another 26 weeks of SQT before being awarded the Trident (and presumably designated a SEAL). So, that's about a year and half after USNA graduation. Assuming there is a break between graduation and the commencement of training, it works out to more than a 5 year commitment from commissioning.
This is for enlisted not officer.
