1. A Dept.of the Army Promotion Selection Board convened on 15 Apr.'75 to consider officers for temporary, AUS (Army of the US) promotion to lieutenant colonel under the provisions of AR 624-100. You were among the officers considered,but unfortunately the board did not recommend you for promotion. Etc... 2. The board examined the entire record of each officer on an impartial basis. Factors such as the following were considered: performance reflected by efficiency reports, civilian and military training, type and variety of assignments and future potential......Hopefully, you will not allow this disappointment to discourage you from continuing to put forth your best efforts in your present assignment.
