What is the new master driver course number in ATRRS?

I can't tell you what the new course number is, however I can tell you how I have been able to find courses for my soldiers. Type "Master" or "Driver" into the course title bar, or course description bar. Sift through the junk to find your course number that you need. Then copy-paste the number into the original search menue to narrow it down to just what you need. Hope that helps.
