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) COL Randall C.
