not bring shame upon myself or those with whom I serve. Spiritus Invictus, an unconquerable spirit, will be my goal. I will never quit, I will never surrender, I will never fail. I will adapt to the situation. I will gain and maintain the initiative. I will always go a little farther and carry more than my share. On any battlefield, at any point of the compass, I will excel. I will set the example for all others to emulate. At the tip of the spear, I will teach and prepare others to seek out, dismantle and destroy our common enemies. I will fight side by side with my partners and will be the first in and last out of any mission. Conquering all obstacles of mind, body and spirit, the honor and pride of serving in Special Operations will be my driving force. I will remain always faithful to my brothers and always forward in my service. CSO selection and training Screening Selection of personnel begins with a screening process designed to identify Marines for the right billet within MARSOC. Operational billets are open to males and females. Only those Marines wanting to serve as CSOs, as opposed to support, must attend Assessment and Selection (A&S); however, all Marines are screened to ensure that those joining MARSOC meet established prerequisites for duty within the command. Screening takes place in three stages: record screening, physical screening and a psychological and medical evaluation. Prior to A&S, candidates go through the Assessment and Selection Preparation and Orientation Course (ASPOC). Assessment and selection Once a Marine is qualified through the MARSOC recruiter's screening process, he will be assigned to the Assessment and Selection (A&S) Program. Phase 1 The three-week A&S Phase 1 is the first phase of selection. This phase is used mostly to determine physical fitness to serve as a Marine Raider and includes running, swimming and ruck marches. The course also incorporates classroom instruction and practical application of basic Marine Corps knowledge and MARSOC and Special Operations Forces fundamentals. Phase 1 completion does not guarantee selection. Phase 2 A&S is an evaluation that enables MARSOC to identify attributes compatible with Special Operations missions and the MARSOC way of life. Individual Training Course Marines selected for assignment as CSO attend the Individual Training Course (ITC), a ten-month program that builds multidimensional operators capable of working across the full spectrum of special operations
