You’re so right. They gave us a choice of firing the 90 or the 106. I had seen the jeep carrying the 106 bounce when it fired. We had to rotate as a team. IOW, you fired the 90 once and your buddy fired it once. You were on the jeep for four firings. Easy choice. No way I wanted to ride that jeep for four shots.
That’s right...a terrible experience.
The .50 Caliber was my favorite.
