Searching for my Father

I am a new member to the site and i am searching for my father who was stationed at Camp Pendleton from 1975-?? He and my mother dated, i was born in 76. my mother passed away when i was a small child and all i have are pictures and a name. Larry Hodgins he has a small cross on his right middle finger as well as a "13" tattoo on his right forearm. i have his Military photo in which he is holding an m-16 and has dark green short sleeve fatigues on. Any info to lead me in my search will help.
