although i never had a chance to actually serve next to abad,me and abad were in the same platoon during basic. words cannot express how big of a heart this man had. I just found out myself and i cannot begin to express how deeply saddened i am. abad was a great inspiration for all of us during basic. he never wore a frown and was one of the most motivated soldiers i have met. it's hard to believe he is gone from this world bit i know he is up there smiling down on us everyday. rip sergio. you will truly be missed by all.
