ASI: U6 school was a great course.
3 weeks in Ft. Sill at A-1/30th FA, 1 week at Fort. Drum( MATES ) site.
Was really good and self explanatory, great and easy to work with instructors. If your interested in working on a -20/-30 level with Towed-105/155mm ask your Section Chief about ASI: U6 / FA Weapons System Mainatainer Course.
