SECF - ET & FT & STS

This site is for ETs & FTs & STS who are in the submarine field. My son is an ET/COMM

New SECF-ETCOMM Mom

My son graduates BESS next week. He is SECF and got his first choice of ET-COMM. Has anyone been down this path and can tell me some details about A school and beyond? All he knows at this point is that he'll be in Groton for about a year and a half. I'd love to know more if anyone can share their knowledge and experiences. Thanks!
