Advanced M134D Operator/Maintainer – 5 Day Training Course

Dillon Aero offers an advanced training course that is designed to train users in comprehensive Operation and Maintenance of the M134D System, and covers much more than the basic weapon familiarization course. In this course, each individual student is allotted extended time for practical hands-on exercises with the M134D System, under direct Dillon Aero Instructor supervision until 100% competency is demonstrated, and instructor-confirmed.

Once a student completes this course, they will have the ability to effectively demonstrate safe and effective operation, as well as operator/intermediate-level maintenance, of the weapon system in accordance with Dillon Aero published manuals and guides.

This course will aid, and is intended for those seeking to become an M134D System Instructor at their respective Unit or AOR. Training is comprised of 4 days of in-classroom instruction, and 1 days of live fire instruction. Course instruction consists of detailed explanation, demonstration, and individual student hands-on participation. Dillon Aero provides live weapons, training aids, tool kits, special tools, fixtures, linked inert dummy ammunition and linked live ammunition for live fire range for use during the course.
