Any more after that are &quot;Additional&quot; MOSes (sometimes referred to as &#39;alternate&#39;, but &#39;additional&#39; is the formal name)<br /><br />In order to retain that MOS you&#39;ll have to keep up any training if required (i.e., hypothetical .. you need to have some specialize refresher training every three years in order to stay current) Response by COL Randall C. made Mar 16 at 2023 3:37 PM 2023-03-16T15:37:54-04:00 2023-03-16T15:37:54-04:00 2023-03-16T12:26:45-04:00
