It is with profound sadness that I announce the death of Martin Fackler, M.D. Dr. Fackler was the progenitor of modern wound ballistics. Whether a warrior or guardian, we all owe him a huge debt of gratitude. In my case, it was only through Dr. Fackler's training and mentoring while I was doing my Residency and Fellowship that I ever even got involved in wound ballistics. I hope you rest in peace.
