Marines come to the company from two distinct sources; prior service active duty reconnaissance Marines and newly joined Reserve Marines who contracted for the 0321 occupational field. Additionally, a limited number of non reconnaissance prior service Marines are accepted for retraining. Prior service Marines begin their selection process by contacting the I&I 1stSgt to set up an interview and review of their service record. The 1stSgt can be reached at 510.814.1608 ext: 222.
